Exhaust choice???

rocknroll · Jan 28, 2008

Hi all,

I'm new to this forum, just bought my first sn95, a 96 GT.

My question is what kind of exhaust should I run?

The car currently has longtubes w/catted h-pipe and a Flowmaster catback. I think it's just obnoxiously loud. I've had a foxbody with Flowmasters and an off-road h-pipe that wasn't this loud. I'm wondering if the longtubes are the cause?

Also the car is running an Allen supercharger so I need something that flows pretty well while at the same time having a mellow-er tone.

Any suggestions?

Thanks

It's the longtubes. Really the only thing to quiet it down would be some 50 series Flows? Not really sure.

The only way to really get a "mellower" tone would be to get something more restrictive :dunno:

I've been looking into the MAC pro chambers, a few posts where people quieted down their exhaust with them. Might start there and then swap out the catback if it's still too loud.

I've never heard a catted setup that was obnoxiously loud, especially with chambered mufflers. Are you sure the cats aren't gutted?

They may be. There's actually a rattling coming from the h-pipe and I think it's a piece of one of the cats that came loose. Probably from someone trying to gut them. The guy who had this car before me was a hack so I wouldn't be surprised.

I know a guy who actually lost a motor from a plugged cat under high boost.

Flowmaster 50's aren't that restrictive. They are huge though, since they are meant to go under SUV's and whatnot.

I had flows on my blown 97gt, I switched to regular magnaflows and it got more flow and was MUCH quieter.

yea my prochamber isn't that loud unless your getting on it and its o/r . also, you could try sticking a stock set of mufflers on there... they really aren't that restrictive.

I was looking at the Magnaflows, I might go that route. I listened to the exhaust clips on their site, they seem to still have a nice tone to them without being too loud.

Thanks for the input guys, now I just need it to get warm again so I can start working on this thing...
