Guys thats running a single 3.5" exhaust what muffler are you runnning? Id like to have the best flowing but not to to loud. I redid my y pipe and trying to decide if I want to run a cutout with a catback or just dump a single 3.5" muffler. Isn't my DD so I guess that no big deal.

I'm thinking about doing the same thing. Anyone run a single 3.5" moroso spiralflow? Its about $50 and I have heard some good things about it.

the spiral flow is really only good with a dual setup. Regardless of how good they claim the spiral flow flows it really dosent. I suggest getting a 3.5" magnaflow.

theres a lot of choices if youre gonna mount the muffler in the stock location. Do a search at summit.

The biggest oval 3.5" magnaflow would flow good and be reasonably quiet. My old camaro had a similar 3" catback and wasnt too loud driving around. But it did get loud at wot

I have a 40 series flowmaster now and sounds great. But im coming right off the ypipe with a bullet(maybe) and a turndown before axle.
