Ok im thinking about buying the Stillen Cat Back Exhaust for my g35 coupe. I think its one of the best if not the best performance wise. I was just hoping that people that already have the stillen exhaust in their g35 coupe tell me how loud is it on the coupe? Ive heard many different answers. Some say its not that loud and some say there is this annoying droning on the stillen exhaust. I just want to kno which one is true and if the the sound of the stillen exhaust is annoying or not?? It would really help if somebody that responds has heard of the stillen exhaust on the coupe or owns a stillen exhaust on their coupe and not just heard of it from a link. Because it can be hard to tell hearing it from your computer. Thank You.

 

I have the stillen, however, it was installed along with a set of high flow cats so I am not sure I can comment on stillen alone. The stillen + cats is definitely louder than stock. Too loud? I think it is a matter of preference. I do not notice a "drone" (for instance, my old flowmaster set up on my 5.0 Ford used to rattle the interior at 2,000 rpm) but it is noticeably louder than stock. It does not bother me but it does bother older passengers sometimes once it gets above 3k rpms or so. Not too long ago I also added headers, which kicked the sound up a notch also. Hope this helped!
