I'm trying to decide on a new cat back exhaust for my coupe, the three that I like are the ark grip, invidia Gemini, and the stillen. I've heard about fitment issues with the ark and ividia and I don't want to spend hundreds at a muffler shop. If anyone has any experience with these exhausts input is much appreciated, thanks

 

Stillen is overpriced for what it is.

Just my .02.

 

Judging the exhaust systems you chose, you price range is up to $1300? Fast Intentions is the way to go for that price, considering it's only $200 more than the Stillen and same price as the ARK.
