I think I am gonna use these for my true dual setup but are they a good flowing muffler? Say enough support to carry a 550hp setup with dual 2.5" in, out mufflers? I know the setup in the sig isnt pushing 550 but something else is soon to come. So are they a good muffler or not? thanks

Can't be of too much help, but I can take a couple of pics of one I haven't installed yet. I'm going to do duals and mount them under each floorboard. I don't know how they flow but I'll post a pic of the innards of mine. What else can I say.... they're thin!

Just took a Spintech Sportsman off my GTA. It was on there for about 30 minutes. It was way too quiet and it felt like it stopped up the flow. Took the car back to my exhaust shop and replaced it with a 3" Flowmaster 40 and it sounds great and feels like it has way more torque.

Where did you have that Spintech mounted, Joe, and where is the 40 mounted? Do you know which Spintech it was? I might like to try dual 40s sometime in the future, but they're just too thick. If I mount my Spintechs under the floorpan, I will want something quieter than 40s since I will dump them shortly thereafter. Right now I have two 1 chamber flows and they are a little to loud for my taste when I get on it.... I like the idle and cruise, but like I said at WOT they are pretty loud. By the way, my 1 chambers exit at the rear, so the interior noise is not that bad, but it's pretty loud outside.

It was a 3" Offset/Center Spintech Sportsman. It was mounted in the stock location with a single driver's side outlet. The 40 is mounted in the same exact location and same configuration. The 40 rules.

Yea, I would probably put a 40 there too, as opposed to a Spintech, since you don't have to worry too much about interior noise since it exits out the back. But that's just because I like the Flowmaster sound.
