Just Ordered Corsa Cat-back, Get Anything Else?

[mhorn0817]

Welp i finally ordered my corsa touring exhaust for my 04 denali, i already have GMPP cold air intake and a W4M tune, Is there anything else i should do or buy when i put my exhuast? thermostat or anything? thanks in advance

Sounds good to me. I wonder to get the full effect should you have a retune to account for the improved exhaust flow? If it's free for life like most, it could help.

Long tube headers

I was going to say the same thing. I know on my LS1 a set of Jet Hot LT's were worth 20rwhp and around the same torque.

i have definatly thought about headers but i dont want my truck to be loud, thats why i spent the money on the corsa touring...anybody have any exhuast clips with intake,headers,corsa touring? how much do headers runs?
