YOUR STEREO IS OBSOLETE

Make your presence known with the feral sound of the iE Catback for your Audi B9 S5. Thanks to iE’s innovative and proprietary DroneTrap technology, enjoy unrestrained ferocity without the annoying drone. Engineered with mandrel-bent stainless steel, TIG welding, multi-point reinforcements, and oversized quad tips, it’s a beauty and a beast all in one.

LEADING FEATURES

  • Say it loudly -Aggressive, yet refined exhaust note
  • DroneTrap Technology -Proprietary no-drone resonator
  • Aggressive look -90mm slash-cut quad tips 
  • High flow design -Dual 2.5" piping for any power output
  • Easy Install -No cutting, no welding, no hassle
  • 50 states legal -No check engine light & emissions compliant

iE DRONETRAP TECHNOLOGY

iE’s advanced DroneTrap technology utilizes mathematically tuned resonators to cancel out the sound waves that cause drone, leaving the audacious, feral waves free to conjure deep, satisfying roars and rumbles.

QUAD SLASH-CUT 4" TIPS

Add a dash of non-stock flair with oversized, 90mm quad slash-cut exhaust tips. These aggressive-looking tips fill the factory exhaust cutouts, creating a high-end, sporty look.

BUILT TO ENDURE

Sound may be the primary feature of iE’s Catback Exhaust, but durability and reliability play a significant role. This catback is made from mandrel-bent T304L stainless steel, featuring hand-TIG-welded joints and several structural details for added strength and integrity. The stamped, multi-wall muffler prevents warping, while reinforced hangers ensure a secure mounting. Strength-boosting bridged piping distributes weight, reducing stress and vibration. Wide-width stretch clamps ensure tight and leak-free connections.

INSTALLATION

The installation process is straightforward, without any permanent modifications or installation hassles. You’ll need standard mechanic tools, and an auto-lift is highly recommended.

AVERAGE INSTALLATION TIME: 3-4 HOURS

Great facial moisturizer
I use the cream every day as my daily facial moisturizer. It is amazing. I even use it before going to bed as a night cream. Definitely recommend this. I’ve seen a difference in the texture of my skin as well as how well my makeup goes on.

Best Baby Sunscreen ☀️
Size: 6 Ounce (Pack of 2), Style: SPF 50 Spray
Putting sunscreen on a one year old is never an easy task. So I learned very quickly that the spray was a must. I’ve tried several different kinds and have had issues with eye irritation because I’m sure as y’all all know (that I definitely did not know) the first thing they do when you put sunscreen on their face is rub it immediately in their eyes. Although this one is not completely irritation free, I have noticed much less irritation to her eyes (or maybe she’s finally learning not to rub her eyes after I put it on idk 🤷🏼‍♀️). Regardless this is a great safe, easy to apply sunscreen for babies!
