ive been told by a reputable shop but not a sponsor that as far as performance you wouldnt notice a difference but in exhaust note you would.

First of all, how is your ground clearance with your present exhaust system? Going to a 3'' duals, especially if you're incorporating it with an x-pipe will make ground clearance worse.Then again, true duals sounds wicked!

flow wise i dont think so. but I do think that the X pipe has better scavenging over the regular Y pipe which should help make more horse power.

"A 4” Single system is good for a 657hp engine with zero loss…" -lt1engine.com

Just keep the single 4in., save you some weight over running 3in duals.

Yes if your motor at that time will be putting out a good amount of power over that number.
3in. duals will handle up to 812hp with no loss.

^depending on muffler application.....




im going to run a 4 inch mufflex on my new build. the car is going to see 250-300 shot of nitrous on top of a 11.5-12.0:1 compression 396. I think you will be just fine as a friend of mine is running the mufflex on his procharged 383, and puts down some good numbers with alot of tuning troubles.
