You truly get what you pay for their are superior headers for finish and fitment but in the same token you will pay for that difference. Being that you already own a set you have a good idea what your looking at already. But you will enjoy the power the headers un-leash with the LS2.

i love my OBX headers but as stated they will fry a 5 & 7 cylinder wire..mine are wrapped in cool tape and a heat sleeve over it, heat sleeve alone wont do it. a guy on GMFS cut and modded a piece of stock mani heat shield to bolt between the 2 cylinders and hold the wires off the header, great idea. also i had to sawzaw about 4" off my y pipe to get it to fit.

EDIT: sorry for the bump, didnt read thread date

I installed these on my TBSS and picked up a ton of power. Fitment was great with no issues after 70,000 miles on the car ;)
