I love your store but sadly, the JBA headers make 30 rwhp and 35 rwtq with a carb legal shorty header- on a stock car-- Ive seen that dynoed- But I would love to hear customer dynos once these are out

Edit - I guess the JBA were posted with the same ( 12-15 hp) increase - So please post ur own results =)

JBA makes a very good product but I'd like to see some more before and after tests with them. Shorty headers usually don't make that much of an improvement. These numbers are in long tube territory.

You on Crack? I've seen people put on Long tube headers and barely make 25hp increase with other bolt ons. Somebody at JBA has been spreading propganda, even on ls1gto.com its pretty sad they do that. People are gonna buy JBA headers and make a 5hp gain but the payment is already in the mail if you know what I mean.

Someguy from JBA we assume came on ls1gto.com posted a dyno number of a stock GTO that all was put on was JBA shorties and claimed they made 30rwhp. After me and about 5 other people questioned the guy he posted the car was dynoed at JBAs location in San Diego and quietly left.



But to install thoes SLP midlength headers do you have to do anything to the steering rack or steering shaft????

Was that guy running a 408 Iron block with a TREX cam or something through stock manifolds to get that much HP out of JBA?

The only headers that have a chance of being CARB legal are shorties. They don't change the location of the cats.

Those don't look that long at all! Barely longer than shorties O_O (atleast on the F-body..01-02)

Shorty headers usually end right around the area where the back tubes pictured above start to make their curve.

As a comparison, Stainless Works dynoed thier project car (Which I bought) with their 3" header set and matching catback (With cats) at 335rwhp.
