I have not seen one but, it would not be hard to have an exhaust shop to do it. Again as i always say go to a performance exhaust shop and not a muffler shop. Muffler shops do great work most all the time on stock daily drivers. But, if You working on perf. and running forced induction then go to a perf. exhaust. They will understand and go the extra without You saying anything. Most have mandrel bending machines to get smoother flow in exhaust.
Shorty headers for torque in high
RPM's.
Long headers for more torque on the low end. That is what the H2 needs to get it rolling quicker.
Headers are worth it especially in forced induction because if you are going to push more air into the engine it has to have the ability to get rid of it and that includes all the way out the end of tailpipe. I am in fact this winter going to a se of LPE high flow heads that they do not sell on site or tell about. you just have to ask. They are high bt, On My rig the heads are a bottle neck so i have to do something and the nice thing is the LPE do not raise compression any. tat is waht You want a head to do with forced indction as High compression is an enemy of forced induction. High compression is for naturally aspirated systems and that is how with cams etc. they get those huge numbers on HP and Torque.
Would be a disagreement in a group of 20 gear heads tosay which is best. I know i like the forced because if You wan to go bakc it is allot easier to do it. But, it is also easier to get the power on as it is all external.
So in My humble oppinion is that headers are a good thing any time.
Befor I put on SC I ran headers tuning intake all the perf. i could without forced induction and i ran 350 HP at the ground. It was checked with a G-Tech Pro with 10 runs and high and low tossed out and averaged the rest which is more than gtech recommends but, i wanted a larger set of numbers to be more accurate. G-Tech now is as good as most anything you can use as most NASCAR teams have gone to them and guit buying that $10,000 unit I forget the name of it. they found the G-Tech was just as acurate. When I ran numbers I called G-Tech support telling the guy this cannot be true. Tech said believe what it says as it has been proven if used as direction tell you. He said do not be afraid to trust it. It will be in a close tolerance of a dyno.
We are waiting to get the newest G-tech so I'm anxious to see what it does now with SC and good tuning.
Run headers.
Guys I'm full of crap
today so if you want an answer and I have or can get it i will. Ask away.
