I have an 04 GTP. 3.4" pulley, Thrasher CAI, MSD coil packs, 160 therm, reprogrammed pcm, 3" downpipe no cat. Looking to spend about $300 for headers. This is my dilemma, this is my dp Hogan Performance W-Body 3" Stainless Steel Modular Downpipe: 3800 Performance. Im running the straight pipe(no o2 snsr programmed out). I dont really want to get rid of it bc it fits perfect,its really solid, the flex location is where stock was, and it all bolts from the rear manifold to the resonator. What are my options (and links preferably) to upgrading? Should i just buy plogs and a ceramic crossover pipe? or should I buy the headers and modify to what i have already accordingly (if so please explain how in detail)? Is there somewhere I can get a set that just bolts to what I have? I want something simple do if I have to weld a little to accomodate what I have now that is ok. Please help... got money and anxious, I want to run another quarter one more time b4 winter to make up for the first time lol
and to verify how it works, starting from the front of the car to the back goes: front manifold, to crossover pipe, to rear manifold, to downpipe(flex), to u-bend/ Cat/straight pipe, resonator, y pipe muffler, tips. Is this the exhuast system?
