I think it sounds really good! :twoup:

:twoup: That is a beautiful sound...

Whatever the sound, I would never buy from that company. I don't know if this is an original design exhaust from them (GT Haus) or another rip off like when they first copied the Eisenmann design for the E60 M5 exhausts and even put the Eisenmann name on their Meisterschaft exhausts to trick customers, but trust is gone. :thumbsdown:

I'd like to hear the exhaust on the street, and not in a garage, without the help of the echoing off the walls...

Love the GTR and their M3! :drool:

Sounds good. Too bad only #2 and #3 tips are functional.

+1

Some flybys would be nice also. :D

The exhaust sounds nice but would like to see a dyno sheet. Agreed with to Tony.

I think I read on the video it was 90mm piping which is around 3.54in? That is too big I think.

Super cool, but yes, it would be better to hear it in the wide open than hearing it in a garage or a shop where there is so much echo
