just wondering if anyone was running a larger cam and stock exhaust except for maybe a orp and mufflers.

when i first got my cam kit before xmas rolled around and i got lt's i had stock manifolds on for about a month and it was still strong
the lt's just complemented it very well

I did cam first with stock mans. and y pipe. It didnt feel any better until about 4500 rpm than stock. I did heads and it felt better but a little dissapointing. I ported stock manifolds and threw on hollowed cats on, this helped alot and it sounded better, also i installed Flowmaster cat back. Next i tuned with Edit and that made real nice torque difference. Than i put Hooker LT and Hooker off road y pipe and BAM! It felt more impressive than all those other mods, i bet its worth 30 hp and 30 ft. lbs in my scenario. I will redyno soon and post gains. Headers changed sound and power dramatically, it feels killer fropm 2500 to 6800 now, i love it! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
