what kind of setup would give me the least restrictive and quietest setup. I dont want to draw too much attention i have a s/c 355 that dynoed out at 625hp at the flywheel that i am swapping in.

A friend of mine just dropped a 383 into his porche 944 and put Magnaflows on it to keep it quiet. Its a real sleeper. Those I think are your best bet.

BTW: He also has a 250 shot of nitrous He is going to rip me apart on the track. Has blown 2 transaxles so far.

 

what does your friends car run in the 1/4? I put a 305 in a mazda rx7 and that thing is pretty crazy, I'm gonna rebuild the motor this summer(350) with 75hp shot of NOS.

 

I agree with the magnaflows. The exhaust shop that i got mine at had flow tests on a bunch of mufflers, and the magnaflow was just about tied at the top with the slp and borla mufflers. Its a lot quieter too. It still has a nice low pitched growl and isnt to loud. Im very happy with mine so far. The only problem is my exhaust shop couldnt find a whole kit, so I had just get 3" mandrel bent pipe, and mandrel bent outlet pipes separately to go with it. I got the whole thing installed for $300.

 

He hasn't gotten his car to the track yet. I can't wait to see the numbers myself.

 

I would get a dynomax Super Turbo muffler. Flows very well and sounds stock. Magnaflows sound good, but they have the "chambered" sound to them, which to me, made my cam sound lopier than it sounds with a turbo muffler. A 600 horse 350 is gonna need all the help it can get to not attract attention to itself.

 

i think SLP is pretty good and quite, flows realy good.
