Hey, Im looking to get a quiet catback. My warpspeed y-pipe should be coming tomarrow I was thinking about gettin a warpspeed y-pipe and dynomax turbo muffler but I rather have something that will bolt right up. Which catback will be quieter out of the Greddy, Apexi WS and OBX. I searched but I cant find a good answer. Any info would be great...thanks!

 

unless im mistaken (wouldn't be a surprise) but i think the apexi ws is the quietest of the 3 that you posted. not sure about all the others.

 

i've heard greddy sp1, and i have obx (greddy style), they sound very similar and very quiet to me. The apexi i never heard but has a lot of great reviews.

 

I want something looking more classy and quiet too, but I don't know how much longer I'm going to keep modding my max, since I got a project car coming.

 

With a y-pipe you can forget about anything being quiet. The WS is stock quiet without the ypipe, with it it's loud. Unless you add a resonator or 2 nothing will be quiet.

 

whoa, that sux, better keep my muffler stock then

 

Is the Greddy SP2 louder than the SP1? If I cut the 4" tip off any of these mufflers and welded a 3" on there, would that make any difference in sound? I dont really like the huge tip and every catback I see has a 4" tip.

 

bump bump...
