American Racing Headers I have a question, I got a 1998 Firebird Formula automatic stock with a GMMG chambered exhaust, I was thinking about buying some american racing headers, but wanted to know first what hp gains might I be lookin at?
There are a variety of gains in Long Tube headers. Here are my gains.
Stock, LS1s are generally rated 305 HP,
After my modifications....
QTP Long tube headers with HVMC,
TSP True Duals X Pipe
SLP Lid....
348 RWHP 365 Lb/torque...
I think generally you can expect close to the same if not maybe a bit less depending on your exhaust... just now saw it was an automatic. anyways... same answer

car will deff pick up power... a quality set of headers is a great first mod to do... ARH are i feel the best header on the market right now. Call me if you have any ?'s or need any pricing on them.
