Best Headers-HFC combo?

RCZ

1) The difference between the FI longtube and the Stillen headers is probably not noticeable with regards to power. Its like 5hp.

2) Not best, but it makes most sense financially considering the little difference headers make...I'm pretty sure I lost torque with my headers, however all that changes if you ever decide to get forced induction.

Option 2 gets you most of the way there (HP gains, weight savings) for far less money. HFC's are also more readily available (long tube headers have a waiting list) and are an easier install. I went with this option and may upgrade to Option 1 over time if I decide to eek every last HP and foot pound of torque out of the car.

Hey RCZ, I was wondering if you knew what the Stillen HFC's gave you power-wise. And if you got any CEL's?

OK so I asked this question before on another exhaust thread. Will test pipes net you the same gains and FI LTH??????? FI is getting my money no matter what, but I dont want to spend more money if I dont have to. Or will LTH and a CBE net more then TP and a CBE?????????

According to Tony's dyno runs on the F.I. threads, the FI exhaust + test pipes will give you around 308 hp. FI exhaust + LTH will give you around 311. So, it seems to net you around 3hp topend.
Again, they weren't run during the same time period, so the conditions aren't exactly the same, but take it as you will.

A/F seems to be comparable.
