by far and away the SLP dual/dual is one of the best flowing and definately quietest stock catbacks out there.

How about a v6 muffler, 4 cats, a bullet in the I pipe and a supertrapp at the exhaust tip. lol..

Just run the stock exhuast if you want quiet.. anything else will be louder.

SLP dual/dual. Not only is it really quiet but you get all the power gains of an aftermarket exhaust.

im also on the bandwagon ....for stock exhaust....even with just cutouts, youll see a significant gain, and itll still be pretty quiet....

Hands down SLP single side. I absolutely love mine. Power numbers boost, plus quiet smooth sounding ride. What else could you want?

i only gained 5rwhp and lost 1rwtq from stock exaust to open cutout. at the time the car was mostly stock.

Another vote for the hooker, but I know the SLP is quieter

I'd want to get performance out of whatever choice I make, regardless of cutouts. Plus I don't like cutouts, I would rather go true duals. The Bassani true dual kit is very refined, and not much louder than stock until you get on it. But if you have to choose a catback, I would go with performance and sound: Magnaflow.
