my foot is off it trust me... i think it's cause my dp is 3"

or you have an exhaust leak somewhere around the dp/header area.

that's no fun, time for a stage 3 clutch and a lightweight flywheel? I'm a big fan of lightweight flywheels after putting one on my last car, can't wait till I can afford one in the Cobalt.

i think i'm gonna get new gaskets and put the lsj downpipe back on and sell the 3" dp or trade for a 2.5. 3" is too big for N/A the only reason i have a 3" is cause i thought my friend was giving me the XTC 2.5 i got confused. also i followed the how to and it said nothing about a special torque pattern untill i found the same how to on another cobalt site that showed it so i prob have a leak from that....
