Which option would be better, increase in horses, and sound the loudest?

Xemeth

Uhh... You post off road mid pipes and then MAC cats. Do you mean cat-back?

As far as loudest, H-pipe is louder. The LT's, h pipe and catback would be an awesome sound. Cam it and you'll sound as close as you can to a V8 (although never exactly like one).

my offroad h pipe sound like pure sex from mac!

v6Ben35

sweet, sounds like more people are for the h-pipe

but what about horsepower gains, what are ya'll running with the h's?

Xemeth

If you're going long tubes, I recomend using a MAC mid-pipe, just to avoid any possible fitment issues. I say MAC cause they're the only ones that make LT's for a sixer.

I do suggest a Borla GT cat-back, though. Borla sounds AWESOME, but it's really expensive.

cam it. period.

v6Ben35

yeah my friends got the borla for his trans am, sounds real nice, buut im feelin the mac because i like their shape of the tips

Xemeth

You know you can buy tips anywhere. And Borla tips are nicer anyway.

v6Ben35

true and true, but i dont have that cash, plus, i sort of have a thing for those mac tips.

Xemeth

Well, that's kind of a personal thing, so I won't get into that... lol, j/k
