so i recently got a 3 in y-pipe with cut outs and to have it installed along with the most restrictive/stealthy cat back I can get my hands on. I have a 100% stock long block with a crappy "slow master" catback that I hate, so I figure with the cut outs, i can have silence when I want for the sleeper appeal, and open the cut outs for go

On my 98 trans am, I had a crate LS6 with lt's and ory with a cutout and then the stock catback. Sounded just like stock when closed but was f'n loud with the cutout open...I liked the setup so much that I am going to do it again on my camaro now...

Stock is going to give you the the most sleeper appeal, but my flowcrapper is pretty quiet.

I love my SLP D/D muffler setup, but a stock non-SS exhaust would be the quietest.

thanks guy, the stock cat-back seems to be the winner, I just have get some dual/dual tips.

Kingc8r, love the sig, Z/28 FTW!

V6 exhaust would probably be the worst flowing and quietest, but the single outlet with the turn down would look pretty gay. I think some v6 rs camaros or something of the sort came with dual exit mufflers, with turn downs however, but tips would be an easy fix.

You need to get a dual/dual muffler. It's just as quiet as a stock muffler, but flows a LOT better.

Stock. I have Kooks 1 7/8ths, 3" Y, 4" flowmaster merge, 4" cutout, and stock catback. This thing is unbelievably quiet when the cutout is closed!

Cool, I was thinking of getting lts with an ory and just mating it to the stock I pipe catback (I have a cutout). I'm happy now that I can be stealthy still.
