I live in ca, and like with previous cars i do not want to deal with LTs and the smog/emissions and state refs as well. So, jba shorties netted me a 25/24 rwhp/tq gain on my ls2 gto. will they benefit me now on my c5z06 too? i tried searching but it was mainly people who have them loving them but showing no proof of anything, or people with LTs saying they are a major waste of money and time.
So, considering my situation, should i go for some used ones?
what about jba vs b&b or any others?
one more question, i was told that the ls7 manifolds fit. is that true? if so, what would be better/give better gains?
thanks guys
