Hey guys/gals. Got a question ive been trying to hunt down some info. on and so far I havent found anything. Im doing a Lq4 swap in my 98 gmc Z71. As of right now my current status is tear down and planning build options/ setups. My goal hp numbers are 400-450. That being said, due to where I live I will have to Have the truck emissions tested. Obviously this will limit me on me exhaust set up. Can anyone help me out with what other things I will need to check into on this topic? Thanks in advance!
