Exhaust dilemma Well, Ive taken the plung for a big cubes stroker, and I know that If I dont want to bottleneck the combo, I will have to upgrade my exhaust system.
As my plates say (which is mostly just for the humour factor) I prefer a stock appearance and sound. Which is why I have always since Ive owned my car, left the back half of my exhaust factory. I have 1 3/4" pacesetter headers with no smog stuff on it, and a pacesetter ORY. I have this attached to the factory rear half of the exhaust with no cats. In between the ORY and the rear factory exhaust I have an electric cutout. When I want a free flowing exhaust or a loud sound, I could just flip the switch. Otherwise I could cruise around with a fairly muffled sounding exhaust.
I would really like input on what is the most free flowing exhaust system that doesnt sound like Im trying to break windows everywhere I go. I believe I may even jump up to 1 7/8" headers. I was thinking either duals or x pipe. My concerns are clearance, sound, and performance. There are alot of muffler and exhaust brands out there, and I know they arent all equal.

Ive never heard of GMMG, I will look into it, but I would prefer no cats.
Ya see, I dont want it to be extremely loud, its my summer toy and I cruise around town with it all the time, dont want to be getting pulled over for noise. I'm more go, than show/sound.

Hmm, it doesnt appear to be a full dual system... From what I can tell, it sounds awesome as hell. However I am looking to get the full potential from my large cube build.

spintech has a 4 inch exhaust system that you look into, its not duals, but can flow pretty damn good because its HUGE, just make sure you'd get a decent sized y-pipe. Other than that, your only option is duals out the back with a muffler of your choice, or you can run 4 mufflers instead of 2. Do a search on here and look for Kooks 454ci LSx Trans Am that they built. They ran their 1 7/8 headers into an x-pipe and 4 kooks bullet mufflers and then brought it all the way out the back. It wasn't too loud, but it sounded mean as hell...

Duals are loud. If you cam your car with duals, you will go deaf to say the least 
. Clearance is probably a little more than a coke can off the ground at stock ride height. I was assuming you're talking about buying TSP or something, if you're getting a custom catback done for duals over the axel then i have no clue. But dumped preaxle is not going to sound stock at all. X-pipe will flow the best however from what i've read on LS1Tech. A cutout is high flowing as well though... i don't know a catback in particular that can match the flow of a cutout or true duals. If you're going for flow and not tone cutout or duals or even 4" pipes might be a solid solution.

Ya that doesnt sound bad, It's basically a larger version of what I have now, the pacesetter y-pipe with a 3" cutout after the y-pipe mated up to the stock rear section.

I just seen the Mufflex stuff, looks pretty nice. Single 4" systems. How are the spintech mufflers for performance?
