I must say I am a little dissappointed at Stillens dual exhaust for the coupe. It's not as loud as loud as my old Stillen dual exhaust for the sedan. The sedan even had a soft backfiring rumble to it when down shifting. I had the sedan for about a year and traded it in for an 05 coupe. The tone on my coupe with the stillen exhaust picks up a bit and is more aggressive in the midrange rpm but virtualy has no rumble when downshifting and almost to quiet for my taste at idle. I even have Stillens CAI installed and its not any louder. At least the polished muffler cans looks good with polished tips. I don't think it was worth $1300 in my opinion.

Unless they have changed it lately . Mine is loud enough . Did you get the new more quiet one ?

 

did you feel any gains??? supposidly Stillen dynoed the highest results

 

yeah...stillen is the heaviest yet the top-notch gains in terms of hp.
due to its weight, most ppl go w/ HKS...no?

 

i've had mine for about 4 months now.... i actually love the fact that it's quiet when it's low rpm and rumbles when i hit the gas.... keeps the oink off of me.....

 

How long have you had it? The more you drive it the louder it gets. Mine is as loud as hell, but when I first got it it was quiet. Just give it some time. THe intake gets louder too.

 

I've also had mine for about 4 months and I love the way it sounds.

 

Got my car 2 months ago and got the Stillen dual exhaust about 2 weeks ago. I have not really noticed any improvement on acceleration, but it does seem to have a more aggressive tone under hard acceleration. I will just have to break it in some more.

 

I've had the Gen1 on for over a year, probably 20K+ miles. It is still loud but manageable to me. My experience is you need to get the RPMs to 4K and above to get the kick. Coupled with the spacer, above 4K is a fun place to play.
