nice gains man. i dont see why people make the shorty/mid pitstop route and then go to LT's. be easier to just jump to the good stuff :D.

Mac cats suck. It would be interesting to see what the difference would have been if they both had an ORYP. I'm not slamming Kooks, because if I ever get rid of my Macs, I would get Kooks. :judge:

thanks for the replies. i would be happy if i just gain 5hp & 10 tq in my switch.i see people say mac's cats suck,i would'nt know i dont have cats. THANKS ALL.

I dont think its worth any hp to switch personally

headers are headers, your talking just a couple hp either way you go regardless of that post with the cats. i have several friends with ls1 cars, most of them have basic bolt ons and headers and OR-Y pipes or true duals, the duals cars make alittle more high end horse power but every one els dynos so close its not even funny, with vertiualy every header for the ls1 being represented, and to be honest, the guy that truly gained the most from his before headers after headers dyno was a guy with a set of paceseters, i thinnk he picked up like 26 while every one else was between 18 and 24 those inlude the macs as well, it just goes to show that more expensive doesnt equal more hp with the macs and the pacesetters being the cheaper of the headers, they make just as much hp. and macs have a dissadvantige, there only mid length.
