Nice 1st run of Bank Headers...Those things heat up way to much...they melt everything...
I've got the new Banks Headers and they totally kick ass.!!! They have a new heat shield built into them and they add around 10-15 HP.
If you buy them, make sure you have the correct part number... Some guys are still selling the 1st run of headers which are worthless!! I ordered them straight from Banks..
FYI - ever look at the inside of stock Jeep manifold's??? Its like 15 grit sandpaper in there. Plus the stock manifold's crack a lot. The inside of the NEW Banks Header's are smooth as ever... Made out of hardened Stainless with a coating over them. They will last a lonnnnnnnnggg Time. Don't believe what other people say, they truly add HP. Sure you could get a plug in computer... I've got one.. But that's all you get...
The sound - more like a V8 and less like a V6. Trust Banks...They test all there stuff!!
Hunt around, I got my Headers for around $550.
And anyone that says you don't notice a difference with a cat back exhaust system...is an idiot... anything you do to your exhaust to let the air flow better with less restriction will give you better mileage, more HP, and a deeper tone (less like a Lawnmower).
I know, lets keep all the stock stuff on the engine, just plug in a computer and say "YeaH, I get so much HP" If you really want HP, then open up the head's & Intake and polish everything that accepts air mixture and air into the engine...Mess with the valve's, add roller rockers, diff. cam ...blah blah blah......Thats how you make real HP!!
