Description Fitment Guide

CTS Turbo Mercedes-Benz M177/W213 E63S High-Flow CATS are made to maximize exhaust flow for highest power gains.

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

In addition to unleashing the power and performance of your 4.0 Twin Turbo, our downpipe will make your vehicle sound like it really should. When installed with factory exhaust it produces a louder and deeper growl with much more pronounced exhaust “crackle” on downshift. While up-shifting you will enjoy a confident “punch!” as you bang through all the gears. The sound will be even louder if you already have an aftermarket exhaust system.

Product Details:

  • 70mm/2.75″ stainless steel pipes
  • Cast T304 stainless steel, TIG welded back-purged construction
  • Replaces restrictive factory catalytic converter
  • Fits within OEM heat shields
  • Great power upgrade with uncompromising performance
  • Incredible sporty exhaust sound, subtle when cruising
  • No drone with factory exhaust

To remove the CEL that will occur, proper stage 2 tuning software must be used.

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!
