YOUR STEREO IS OBSOLETE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

Fits 2001 325i
Material Type: Carbon Fiber
I love my 2001 E46 (325i), but one challenge is that the plastics no longer remain "dry" in the summer heat, instead becoming a sticky mess. Picked this up to replace my existing cup-holder. I was optimistic that the black carbon fiber mesh would blend in with my otherwise black interior, but it's not the same shade of black, so the new part looks a bit out of place. No worries, I just need more carbon fiber replacement components! This fits perfectly, snaps into place, and is definitely an improvement over ~25-year old plastic. Great value too, an inexpensive upgrade that has real functional improvements -- items in the cupholder no longer get discolored with "sticky" plastic in the sun.

Works as expected
Style: HEPA
This filter fit just right on my FJ cruiser. Snuggle fit and no issues. You can't tell this apart form other cabinair filters. Smells like the same clean smell when you first change it.

Super tight fit
Style: PUREFLOW
It fit but only barely in my 2006 Subaru Outback, I had to bend it to cram it in so it creased up a good bit.
