Default SLP ls6 manifold

I wanna put a slp ls6 manifold on. I am also putting a complete 3.42 rear end I got from a friend for basically free, so I'm getting there! Anybody do one and notice some good gains? I hear its about 10rwhp. I do have a stock P&P TB. Thanks

Don't waste your money getting it from SLP unless you have to run EGR. Check the for sale section and you can usually pick one up for a little over $300

Hey bud the one i had picked up a proven 14 rwhp, noticeable in the mid to upper rpm range, definately flows better than stock, as to why maybe someone else can chime in, as i was wondering this .
