I have the UltraFlo SS, I like it.. it is not "loud", but has a nice deep sound, and does sound good when you step on it. came with a aluminized steel mandrel bent one peice I-Pipe, Stainless Steel muffler, turn down pipes, and all clamps etc. Worth the money (even for being in Canada).

I had dyno max with a super turbo 2, it was nice a quiet. I now have the hooker aero chamber, and I wish I would have done it the first time around. I love the sound of the hooker.

My friend has an 88 IROC 350 TPI with SLP headers and a Dynomax catback. I must say, I was not impressed at all with it. Its quite quiet at idle, but doesn't sound bad at WOT. Mines louder and deeper though
