I have never taken it to the track. Stock porting pacesetter header with 2 glass packs. still loud like killer bee.

Yeah, that is loud. Basically you are running a straight pipe. When I run only headers, my car runs alot better than with my RB muffler! I hate the RB muffler although it does quite the engine alot! It is all a comprimise. You should run it at the track and post some numbers, I dont know about where you stay at, but around here it is under $15 to test and tune. I think it is about $12

 

I would like to go to the track but without posi in the rear I just cook the tires.Wally

 

I ran many times with my **** rear end, before I put my LSD on. Obviously, it should hook up better with atleast LSD, but you can have fun with out the LSD. Also, make that " cook the TIRE" not tires. Ha, ha! Either way you get a better time by running it, instead of watching other people run theirs. The adrenaline rush is better behind the wheel, then behind the fence! Espescially when the track is packed!
