Default sweet thunder
does any one run thses mufflers? i have a set and i was wondering if these choke up your exhaust at all. i had magna flow duals for a while but i switched to sweet thunder for ground clearance, anyway it seems like i lost noticable power. does anyone know anything about this?

i have one in a y setup. they sound really good..about as close as you can get to the gmmg catback. a friend of mine ran a single one dumped like me on a 450rwhp car. so i don't think they are a restriction.

I <3 my GMMG. It'll sound great. My best friend found a stainless sweet thunder he's putting in place of his resonator on a LM1. Cross your fingers for a great sound. lol

I have them on my TSP true dual system with Pacesetter Longtubes. I think they sound great! If you look at them, they are a straight-through design. There's really no restriction. They're very loud and I'm very happy with them right now.

that's a pic of the inside of a sweet thunder...

i mean, its straight-through, so how restrictive could that be?

i wouldn't say that they flow as well as a bullet, but the sound is much better IMO.

i would only seriously worry about any difference in flow if i was making well over 500rwhp.
