Invidia CBE with Motordyne ART pipes and AEM cold air intake.
If you don't want a raspy sound stick with stock cats lol, the least raspy and loud test pipe set up would be something with the ART pipes imo. A lot quieter and less raspy than normal resonated test pipes. I've been through only a couple of exhausts but went back to Invidia at the end. Definitely one of the cleaner and less raspy sounding exhausts with test pipes.
