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 Competition Series Catless Downpipe, more power is unleashed!  You will feel the difference instantly. 

Our Competition Series Catless 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 3.5" 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. The factory donut flange design is retained.  100% bolt on.

Our downpipes are designed to fit perfectly with either the factory exhaust system or your aftermarket exhaust system.  There are no compatibility issues whatsoever.  The downpipes will come by default with brushed finish.

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).

A royal pain to install
The width of this item is such that it CANNOT be attached to the wall studs. That is unsafe for something that is intended to hold heavy items like liquor bottles. THEN the anchors that come with it are flimsy so we used a heavier different style anchor (threaded). That said, I like the way it looks, and the light effects.

New Bourbon Shelf
I just got done putting it together and hanging it on my wall. It took approximately 35 minutes to put together and another 15 minutes to hang up. I had to use my own larger wall anchors and screws. I tried the ones that came with it but they didn’t do the job. I am happy with it other than that. Good value and quality materials. As you can see from the picture it holds several bottles and room for more if I want. I think the LED lights look great as well.

The Last Cutting Board You’ll Ever Need – Bamboo Perfection
Color: Glue-Free Surface - Round, Set name: Set of 3 (S, M, XL)
I’ve gone through plastic, cheap wood, and even a couple of “premium” boards that warped or cracked within months. These bamboo cutting boards are in a league of their own. From the moment I unpacked them, the quality was obvious — smooth, dense, and beautifully finished with a warm, natural grain that looks gorgeous on the counter. Performance is flawless: Knife-friendly – No deep gouges, even after heavy chopping. My blades stay sharper longer. Gentle on hands – Lightweight but sturdy; easy to maneuver, yet doesn’t slide around. Zero warping – I hand-wash and air-dry, and they still look great after daily use. Juice groove actually works – Catches liquids without overflow (perfect for carving chicken or juicy fruits). Bonus: They’re sustainable, eco-friendly, and naturally antibacterial — peace of mind when prepping family meals. I bought the 3-piece set (small, medium, large), and it covers everything from quick garlic mincing to full meal prep. No odor retention, easy to clean with soap and water, and they double as stylish serving trays for charcuterie night. If you cook even semi-regularly, treat yourself to these. Durable, beautiful, and built to last a lifetime. Worth every penny — and then some!

Excellent Buy
Color: Glue-Free Surface - Round, Set name: Set of 3 (S, M, XL)
We are in an ongoing process to reduce our dependence on plastics. These bamboo cutting boards are stunning, very well made, and easy to care for. I do recommend a wax to keep the surface shiny. Delighted with this purchase!
