The CTS Turbo High-flow Cat for BMW N55 (Electric Wastegate) is made to maximize exhaust flow for the highest power gains. Do not compromise performance and sound with factory parts – unleash your BMW’s potential!

Designed using the latest in CAD technology; this part is made to fit perfectly in place of your factory downpipe. Manufactured from T304 stainless steel, hand TIG welded and back purged to ensure years of reliable performance.

Product Details:

  • Precisely designed and tested on a real car in the real world
  • T304 stainless steel, TIG welded back-purged construction
  • Replaces restrictive factory downpipe

Forge intake pipe

Some slight modifications to the car and the cold air heat shield was needed but otherwise it fit great. Can really hear her breath now!

Very nice!

Love my new side markers - very clean looking and unique in how they flash when turning left or right. The only suggestion I’d make is provide instructions for both installing them and for being very careful with the wire once you disconnect the old light housing Left side went in ok, but I lost the right side into the fender black hole which required me to remove the tire and unscrew most of the lining so I could find the wire!

Much better braking

I was considering just upgrading the brakes altogether, but I decided to try red stuff brake pads first. They are exactly what I needed.

Works great

I’m using these in my 8J TT with some Defi gauges. It requires some disassembly of the stock pods to use with these pod adapters, which was the most complicated part of install. Works great. The pod adapters push the gauges out a little further than the photos represent but I found it acceptable.

Works great

Have had one of these on my 8J TT RS for a few years now. Works great. Installation takes just a few minutes. I only needed to use one of the three available tap ports; I used blue loctite to help ensure the plugs don’t back out (or fall in).

I like them!

This product is fantastic! The smoked side markers look incredible, and the sequential leds are a huge upgrade. Installation was a breeze truly plug-and-play and I had them on in minutes without any hassle. They really modernize the car's look. Highly recommend!

Perfect Upgrade for My TT Mk1

Totally transformed my 2005 TT Mk1! This German Auto Stuff carbon spoiler looks incredible and was a perfect fit. The quality is outstanding. Installation was quick and easy. My car looks sharp! Highly recommend for any Mk1 owner looking for a premium upgrade!
