Did a search, couldn't really find anythign for what I was looking for specifically, so here goes:

Right now, my GSR is bone stock with the exception of an Injen CAI and a NX kit. I need a better exhaust/header. Now - I want to STAY AWAY from loud exhaust/headers, maybe I've seen 2 many ricers around but I don't want that typical annoying buzzing sound coming out of my GSR at all RPM's. I do want the addition of power, so my question is..

What is the best/most quiet exhaust/headers out there right now, for an ALL-motor application with some juice...

Thanks!

 

your exhaust is what will make the bulk of the noise so look into a'pexi ws or usdm ITR... header, it's all a matter of what you want out of the car. 2.5" collector seems to be the new craze. i stick with the carb leagal stuff cuz of smog in CA. but then again, my GSR is a daily driver. i have other projects ( other makes)

 

I would go with the 5zigen exhaust. it's pretty quiet when your daily drivin it and can be loud when your rippin on it. Pretty inexpensive too. Any JDM header is great!!

 

apexi WS exhaust

 

just get a silencer

 

Apexi WS


My friend is selling his, it's brand new in thebox for like 375 or something....

 

If you want the most performance and just as quiet as chambered aftermarket exhausts, you should be looking at twinlooped exhausts... otherwise a quiet and modest gain look at the apexi ws and similar designed mufflers.

 

DC Sports 4-1 header, Greddy SP exhaust seem to be a good match.
