Restrictions in the exhaust system robs horsepower and torque especially on turbocharged cars.  Thus, removing as much exhaust flow restrictions will increase horsepower and torque significantly.  The factory catalytic converter found in the factory downpipe is a big culprit of this and is a major exhaust flow restriction. The factory catalytic converter is made up of catalyst material formed into "honeycomb" weaves. Exhaust gas must pass through these tiny "honeycomb" weaves on their way to the exhaust system thus causing a major exhaust flow restriction. It also causes turbulence after the catalytic converter which causes the exhaust flow to slow down (which increases restriction). By replacing the factory downpipe/catalytic converter with our Sports Series 4" High Flow Metallic Catted Downpipe, more power is unleashed! 

The factory catalytic uses a 900 cell ceramic core. What the 900 cells means is that per every inch, there are 900 "cells" that the exhaust gas must pass through. We use a 200 cell metallic core. By having less cells per square inch, these individual "cells" are bigger in size thus allowing exhaust gas to pass through it more easily. Thus, the lower the cell count, the higher the flow. Higher flow = more power, faster turbo spool up (less turbocharger lag) and better throttle response. Bottom line, faster. The benefits of a metallic catalytic converter vs a ceramic like the factory is that it can take higher temperatures and is more durable (last longer). They are also lighter than their ceramic counterparts.

Our Sports Series 4" High Flow Catted Downpipes is constructed out of 100% 304 grade stainless steel and utilize mandrel bent piping.  They are 100% TIG welded by our in house fabricators and built in the USA.  The factory turbocharger turbine housing utilizes a 4" V-Band flange which we have duplicated and CNC machined cut out of billet 304 stainless steel.  Stainless Steel CNC machined O2 sensor and laser cut brackets are TIG welded using stainless steel rods.  The O2 sensor is positioned at the factory location.  Since the outlet of the turbocharger is 4" and the factory exhaust system is 3", the factory downpipes reduces size using short transitions from 4" before the catalytic convert and 3" afterwards.  Due to space needed for the cataylic converter, the factory downpipes reduce in size using very short transitions.  Since our catless downpipes delete the cataylic converter, we have more space.  Thus, we use very long transitions.  These longer transitions allow the exhaust gas time to smoothly transition from the larger piping to the smaller.  This results in less exhaust turbulence and backpressure which again improves throttle response and increase turbocharger spool times (less turbocharger lag). 

The factory downpipe utilizes a flex bellow section that allows the exhaust system to move.  This eliminates undue stress on the exhaust components like the exhaust system, downpipe, turbocharger and exhaust manifold.  Many of our competitors do not feel it is important to keep this.  While you do not see any adverse affects right away, over time, the stresses caused by not having a flex section and having a rigid exhaust system will cause premature wear and tear.  Any stress failures like cracks will form quicker than usual on exhaust manifolds and exhaust components.  Also, without a flex section, the exhaust system cannot properly deflect impact.  Especially on lowered cars, whenever the exhaust system contacts the ground, the entire system gets pushed up.  Without a flex, you can imagine how much stress is put into exhaust components like the exhaust manifold when the exhaust is pushed upwards.  We fully understand that durability of our products is important.  Thus, like BMW, we incorporate a flex section into our downpipe.  Our flex sections are 100% stainless steel (cheap flex sections only have stainless steel center braids and steel caps) to ensure corrosion resistance.  

xDrive (AWD) Version

On xDrive all-wheel drive models, there is a driveshaft running from the transfer case to the rear differential that the standard front wheel drive cars do not have. This driveshaft sits right underneath the downpipe and blocks the removal.  On a typical installation, you would need to disconnect the driveshaft (requires special driveshaft tool) or lower the front subframe to give enough clearance to remove the downpipe.  This adds significant installation time and complication to the installation.  Our solution is the 2 piece xDrive version allows you to remove and install the downpipe without removing the driveshaft or lowering the front subframe.  This will save you considerable time (money) on installation and allows quicker, easier servicing.

OPTIONS

Ceramic Thermal Coating - The purpose of ceramic coating downpipes is to keep heat from the exhaust gases inside the downpipe from radiating out. This keeps underhood temperatures lower and less heat absorption by nearby parts/surfaces.  Another added benefit is that by keeping in heat (energy) in the exhaust gases inside the downpipe, exhaust flow velocities stay up, resulting in lower backpressure. The ceramic coating also adds additional corrosion resistance. We utilize the best ceramic coating possible. Our thermal coating can resist up to 2000F of heat. It is available in black only (all the other colors cannot withstand the high levels of heat).

Additional O2 Sensor Bung - An additional O2 sensor bung can be added so that you can easily add a wideband O2 sensor and gauges for you to monitor air/fuel ratios. The additional O2 sensor bung will come pre-installed with a plug so that you do not need to run the O2 sensor right away.  This is not required for a normal standard installation.

Optional EGT (Exhaust Gas Temperature) Bung - An additional 1/8" NPT bung can be added so that you can easily add a EGT sensor and gauge. The optional EGT sensor bung will come pre-installed with a plug so that you do not need to run the EGT sensor right away.  This is not required for a normal standard installation.

Nice mask! Caviar
Scent: PDRN, Size: 4 Count (Pack of 1), Scent: PDRN, Size: 4 Count (Pack of 1)
The first 3 pictures were taken after the first hour and a half. The second 3 pictures were taken at 2 hours. The mask had a hard time dissolving underneath my eyes and around my chin area mostly but everywhere else it hardened within the first hour or so. I will try to wear it for longer than 2 hours next time. To see if that changes, but my skin feels really nice right now. It's a little sticky, but it looks healthy and has a nice glow. Application is easy. I love that its separated into 2 parts. Doesn't fit well around the nose between the eyes and doesn't cover my entire face but its a great mask. I tried the caviar one this time. I have the collagen ones as well but these have better reviews. They seem to work effectively, for a nice glow and self pamper session.

My Favorite Mask
Scent: Collagen, Size: 4 Count (Pack of 1)
I’ve been really impressed with this Bio-Collagen hydrogel mask! It feels incredibly cooling and soothing on the skin, especially after a long day. The overnight wear is a huge plus—you wake up with your skin feeling noticeably more hydrated, plump, and smooth. It doesn’t feel heavy or sticky, and it stays in place better than most sheet masks. After a few uses, I’ve noticed my skin looks more refreshed and even, and my pores appear a bit more minimized. It’s a great option when your skin needs a little extra boost or before an event when you want that “glow.”

Love ❤️ this product! 100% recommend!
Scent: Collagen, Size: 16 Count (Pack of 1)
My initial encounter with these was until TikTok but I ordered them from Amazon for myself and my daughter for convenience and Prime shipping. There were two choices I think the one is a four-pack and the one I got is a 16 pack. The 16 pack will last you 4 months if you're doing it once a week as instructed. I open the top and two sides when I'm doing it just to have accessibility and to be able to use the remnants liquid in the pack after I'm done applying the facial part I put the liquid in the pack on my neck and chest. They are a little slippery when you take them out. I watched a video on how to apply it and did the bottom part first and then the top part sometimes I have to snip the top part near the nose to get it to fit properly but you don't have to in general. There are three pieces that are left over the two eye pieces and the lip piece. You can put them below your eyes or above your eyes on your brows and then put the mask over them which is what I do. Or you can put them under your eyes and put the mask over them but I find it doesn't absorb all the way in that location due to the double thickness I guess. The lip one you can put over your lip or put it on vertically over your throat where the skin can get a little saggy. Once you have it on it's best to sit back and relax for 30 minutes or so at about a 45° angle so it doesn't slip off. After about 10 to 15 minutes it doesn't slip around as much and after 30 it's obviously started absorbing and tends to stay pretty well. I haven't noticed any staining on the pillows or anything like that from it and by morning actually by 4 hours later it's completely absorbed and all you have left on your faces the plastic that it was attached to. You just pull that off and throw it away. It's white when you put it on and it's clear when it absorbs. I definitely noticed an improvement in my skin quality and the collagen sinks in easily and less about a week. I am a redhead with delicate skin and I haven't had any reaction to this product at all I know that other masks have caused problems for friends but I've used this one for over a year now and I love it. My daughter and I both use it weekly and they're easy to take with you if you're traveling great way to pamper your skin after a day outside on the beach. The price is reasonable for what it is and what it does. I've gotten several compliments on my skin and I'm over 60 so that saying something for the results! All in all this is a very good product, it doesn't smell and doesn't seem to have any impurities like some others. My skin isn't irritated by it and looks great afterwards. If you're wondering if it washes off once it's soaked in you can wash your face all you want but you're just going to have beautiful glowing cheeks. I wouldn't hesitate to recommend this or give it as a gift!

Great Lotion for the price
Size: 32 Ounce (Pack of 1)
I recently picked up the Queen Helene Cocoa Butter Hand & Body Lotion, and I have to say, it’s quickly become a staple in my skincare routine. The first thing I noticed was the rich, creamy texture. It glides on smoothly and doesn’t leave that greasy feeling that some lotions do, which is a huge plus for me. The cocoa butter scent is delightful but not overwhelming. It reminds me of a warm, cozy day, and it lingers just enough to be pleasant without being too much. I usually apply it after my showers, and my skin feels so hydrated and soft for hours afterward. I also appreciate that it comes in a big 32 oz size. I feel like I’m getting good value for my money, and I don’t have to worry about running out anytime soon. Plus, it’s versatile—perfect for both my hands and body. Overall, I’ve enjoyed using this lotion, and it’s definitely helped to keep my skin feeling moisturized, especially as the weather gets colder. If you’re looking for a budget-friendly option that really delivers on hydration and has a lovely scent, I’d recommend giving this one a try!

Queen Helene Cocoa Butter Hand and Body Lotion
Size: 32 Ounce (Pack of 1), Size: 32 Ounce (Pack of 1)
As someone who typically shies away from using lotion due to its heavy and greasy feel, I was initially hesitant to try the Queen Helene Cocoa Butter Hand and Body Lotion. However, after ordering a large bottle for both my husband and me, I can confidently say that I am pleasantly surprised by how much I love it. One of the first things that struck me about this lotion is its delightful scent. With every application, I feel like I've been transported to a serene beach setting, enveloped in the comforting aroma of cocoa butter. It adds a touch of luxury to my skincare routine and leaves me feeling refreshed and rejuvenated. What truly sets this lotion apart for me is its lightweight texture. Unlike other lotions I've tried in the past, this one absorbs quickly into the skin without leaving behind any greasy residue. I appreciate how effortlessly it spreads and how it doesn't weigh down my skin, allowing me to go about my day comfortably. Additionally, I've noticed that the Queen Helene Cocoa Butter Hand and Body Lotion provides ample hydration without feeling heavy or cloying. It leaves my skin feeling soft, smooth, and moisturized, without the need for constant reapplication throughout the day. I would highly recommend this lotion, especially for those with mature skin. Its lightweight, non-greasy formula makes it a joy to use, and the beach-like scent adds a delightful touch to the skincare experience. Overall, I'm thoroughly impressed with the Queen Helene Cocoa Butter Hand and Body Lotion and plan to continue incorporating it into my daily routine.
