what mods do you have on the car. if its heavily modded id got for bbk long tubes and possibly mac if you want to deal with a PITA install. but if its mostly stock all headers will do is change the way it sounds...so anything will work
yeah the car is mostly stock, I just got it not long ago. I originally wanted BBK Long Tubes except they don't make any that will fit the AOD transmission
hmm...thats wierd i thought they did. check out MAC performance. ive heard some horror stories about the install...but they get the job done if you can get them in. by the way, where in north dakota are you from?
Port the welds out of the openings where they bolt up to the heads. Stock headers are good up to about 280 HP. A guy on here that goes by the name Micheal Yount has a mildly built 5.0 in a Volvo, and went from stock headers to Motorsport 1 5/8" shorties I believe, and he lost 2HP and didn't gain a thing for TQ.
Buy a good H or X pipe, and a good cat back, and while its yanked apart, remove the stock headers and port them inside there,.... you'll see the welds I am talking about.
