How best to mod tips? W216 AMG
My question is this. If I want to get a bit more growl without sacrificing passing CA smog or obnoxious volume, would you guys recommend cutting off the secondary cats and running a straight pipe from the primary to the tips?
Has anyone done this on here with a 6.3? Please try to describe the differences in tone I could expect with the elimination of the cat.
Thank you in advance for your input.
