  • could you tell any difference in performance with the high flow cats?

  • @ppkeaton it's hard to say seeing as i put the headers,cats,and exhaust on all at once. But the overall difference against stock was night and day. Once you get into high flow converters they are all pretty close in performance it seems. Metal matrix cats are supposed to be pretty much number 1.

  • how good are those thorley headers?

  • @ppkeaton I was actually surprised on how good the quality was. Definately worth looking at.

  • Damn sounds badass love the pop n crackle its got to it. I love my 40 series on my sierra

  • meh, about 400 bucks but he has headers so probably 600+ heh. but well worth it if you want a nice sounding exhaust without gutting cats and whatnot.

  • What kinda exhaust?

  • Hey how big of a difference can you tell after driving with the headers? The gain in performance worth the price?

  • @eaglesguy92 if you're gay

  • sounds damn good

  • lol just take the fuckin muffler off it's the cheapest thing to do and it's louder than a 40 series by far
