Greetings all,
We just wanted to share some pics and a quick video of a recent exhaust install we did a customer's 2011 AW E92 M3.
The original customer review thread can be found in the below link.

The customer had already installed RPi Section 1 ( cat delete) and Section 2 (X-Pipes) and Section 3 (GT Race) previously, but wanted to try out the new GTM system, which eliminates the "rasp" issue that was prevalent with RPi's earlier iterations of their exhaust system.
The fitment was very good and bolted right up to the existing RPi X-Pipes. It totally eliminated the “rasp” noise that the customer was not too fond of.
The end result was a sound unlike any other, very aggressive and opens up the true sound of the powerful S65 V8 engine. Check it out yourself in the video below.
