What Headders are you running to be smog legal and what gains did you get from them

i have Edelbrock shorties, all shorties have to come with the smog adapters and a CARB number in order to be legal. As far as gains i cant say for sure, i did all my echaust at once, that alone on a completely stock car gained like 15hp, but i noticed a big difference when i went from a paper filter to a K&N FIPK set up. like another 25-30 hp from that.

I used to have JBAs on my old Camaro. Not sure if they helped much at all.
With SLP Lid, Magnflow Exhaust, LS6 Intake, and JBA Shorties, I only put down 323whp.

I had some edelbrock and they were pretty good. Don't know the numbers but I could tell a difference.

Your gains from Shorties vs. LTs are going to be really minimal... not too much bang for your buck.. might be better off going a diff. route... my reccomendation is finding a smog shop that will "work with you" =-)

I have hooker shorties and I like em. They definitely gave me a boost in performance. As far as how much I don't know I never go to the track. I like to stay legit that way when smog time rolls around I don't have any drama in my life.

Are you smoking crack? I just took off a set of JBA shortie headers w/stock y-pipe and just went to a Kooks 1 3/4" LT and off-road catless y-pipe and a SSRA and picked up almost 6/10th's of a second. And that was on the first and only pass, short shifting the car. Mind you, there was no additional tuning done either. This set up has made a tremendous difference for me and I consider it the best bang for the buck for me so far.

well..first off........... what I'm saying is that statistically LT's are going to give you a considerably bigger gain than shorties... (which you pretty much just attested to)


Also you clearly werent paying attention to the thread.. w/ your LONG TUBES and ORY............... He's asking about cali smog laws... Long Tubes and No Cats = Insta-fail in cali

What I'm trying to say is that if you're trying to stay smog legal, there might be some better ways to spend you money.....


and no,there is no crack smoking going on here.......

Short tube headers gain 8 - 12 hp on the LS1 according to one manufacturer.

Here's why there is so little gain (from a borrowed picture):

The LS1 exhaust manifold is pretty efficient to begin with so short tubes aren't going to benefit a lot.

I would think that for about the same money and effort you could port match the stock manifolds, then extrude hone them. You might pick up the same small gains you get from shorties, and nobody doing a smog inspection would care because they are stock manifolds. They would also fit like they're supposed to, and be super durable.

JBA's work ok for me.
Would love LT's but just don't want to deal with smog **** headaches here in So. Cal.

I used to have jba shorties and they sucked. Then I got some pacesetter LT's and 3 in catted Y pipe and it made a big diffrence. LT's FTW!!!!!!!!!!!!!

I will have some edlebrock shortied for sale in about a week and a half. Pm me if you want them. I am going to register my car in AZ and going with LT.

Went from log style factory manifolds that had been ported to JBA's. No seat of pants diff, only a dyno would tell..IMO, every little bit helps, so I run them. Dont have to worry about smog ***** either!

'99 Z28 with JBAs, noticed a big difference with the JBAs, that was before the LS6 intake, Ported TB, and UD pulley. I noticed a bigger gain from the shorties than the Intake,TB, and pulley combined. JBAs FTW!! (in Cali anways, on a stock cam) Get some shorties and have some pipes made to replace your cats, just bolt your cats back in at smog time.
