So im about to do this install and i have a few questions hopefully someone can answer. . .

Which combo will give me the best gains? As far as J-pipe with pre cat deletes and Race pipe OR just j-pipe and Race pipe OR just J-pipe and Pre cat Deletes?

Also, Which will throw a check engine light and which wont. Thanks

Well all three will give you the most gains.

If you can only choose two, do the precats and j-pipe. None of them should give you CEL's anymore...

^^^ +1. I think the difference between the race pipe and resonated one is like 1 or 2 hp if even that.

well id say you have to do all 3 because once u do the cat delets the 3rd cat will be slowing you down nd gettin dirty, which will slow you down... and as for check engine you should be ok...
