Honestly I was speaking for more stock to bolt-on type of engines, what kinda track times do you see with that combo, sounds nasty... What size header primary are you running?

 

thats cheatin my answer was for the stock guy u got bigg enuf motor to run whatever u want lol

 

have almost all the bolt ons, i have 22" wheels and i tow my drag car to the track. just looking for more power

 

thats what i run. probably not the best hp set up, but damn it sounds good. not much loss down low, just don't use 3" pipe use 2 1/2". if you worry about low end loss use
2 1/4" pipe.

 

Just a single muffler turned down still sounds great with the lt's and no cat. You could split it after the y-pipe and put a second muffler on but IMO you'd just be adding restricion with the second muffler.

 

Just go 2 1/2 if you got full bolt ons and and I think that would be a good set-up.. Gonna go with a X pipe correct?

 

yes make sure you xpipe it or hpipe it. go with 2.5 or 2.25. as long as you do 2 mufflers it will sound good. I had about the same setup but with a dual in dual out magnaflow and xpipe. it was ok, I did not like the muffler. now I have 3" ory and a 22" 5x11 case magnaflow and no cats, and it is quiet...very....quiet. ran thetips out the side in front of the rear tire. like this
