Thread: Red 2006 Grand Prix GT Supercharged

Headers are a love/hate. You'll love then once there in and leak free and you'll hate doing them. Not sure if I mentioned it before in the past but you'll need a o2 extension for the rear...you can easily make your own..that's what I did.

Yeah my dad will mostly be doing them haha! But ill be there to help n read directions n hand him tools hahah. I have two tubes of copper rtv and the extension. My dumb a bought one from zzp for $25 bucks but I bought clamps n rtv from them too all at the same time so threw it on there.

Ill check to see if he has a socket set..you talking for the downpipe bolts or just all in general? I have a zzp flex to swap with and talked with a welding shop about the ubend being deleted n they want it on the car first for the right degree angle. I could have made the jig but since I dont weld it myself its too much of a hassle for me to take it to them n have em do it. So I said okay n ill bring it to them after. What do you mean about the o2? Shoukd I have them weld my cat back on too? Or just get rid of it, does it decrease mpg? Or just make the funky smell from exhaust lol

Yeah when I said socket set, that's what I meant, sorry lol. N I was thinking to just have the welding shop put my cat back in? If it runs smoother n better mpg with it on I'd rather keep it. Did you get rid of your cat or put one back on? We don't have emissions testing here in MI, but if it helps to keep it, I'd rather do that.
