anyone have the Stillen cat-back exhaust on their vert? Another post suggest this is the only onle that bolts on without modifications.

 

I do have the Stillen Catback dual exhaust. I unfortunately, in this case, bought the car with it on. So I don't know about fitment issues, but it looks like it went on pretty smoothly. Sounds quiet at low rpms and growls around 3500rpms+

 

I have it on my 2012 Vert. Sounds great. No problem with installing. Then added Berks high flow cat. Sounds even better

 

I ending up going with ARK. Installation required some modifications, but it sounds great!

 

what kind of modifications?
