are the stillen exhaust worth it?

 

Is?

It all depends on what you want. Sound, performance, weight, etc. What do you want?

Personally I love it.

 

Which one ... daul or single?

 

Really enjoy mine. Looks good, sounds great, honest RWHP gains.

 

Agreed! Definitely worth the money IMO.

 

I'd watch for a used one and pick it up for around $700-800. They look good, sound good, and aren't restrictive. I'm making over 500whp with mine.

 

installed my Stillen Y-pipe yesterday.....took about an hour DIYdirect bolt-on.
Best mod so far besides the UR pulley. You can actually feel the hp gain and it sounds much better wot. DEFINITELY WORTH IT.
BTW its lightweight also.
