damn, those very well may be 1 7/8" headers! The collector looks different than the standard OBX's too. Hmm. Someone email the seller.

I have the hump style ones on mine and love them.Only downfall is it will fail inspection unless you get a tune for rear 02 delete or if some one made simulators for our trucks.If they do please let me know.Hump doesnt bother me.

contact SBChvy for a tune...he's in mechanicville and has done my 2000 and I want him to do my new truck...might be worth a shot and nice seeing u guys are near by for re-tunes...

FWIW, I had the hump style on mind and had zero issues...would buy these for my truck in a heartbeat

I'll probably end up with them myself. The only question is whether or not the Y pipe will work. I'll probably just have a custom catback made.
