I want to upgrade the exhaust on my 4 door GSR and do not want anything loud. Has anyone heard anything good or bad about the apexi world sport exhaust? Any other brands you recommend that are relatively quite?

 

I have one, and love it. It's barely louder than stock inside the car, and a little louder than stock outside. Well built, the tubing is not stainless steel (aluminized steel), but the muffler is stainless.

Butt-dyno says more midrange, at about 3.5k - 6k rpm it feels a little stronger than before.

For the money I think it's great.

Cheers,
Roy

 

DC Sports has a good exhaust also....it's not too loud. But it can get loud when you're revving.....and it's a deeper sound, not like a lawnmower...

 

Apexi WS is dope YO!

My brother has it on his 4dr and I like the sound. Good looking exhaust too.
