I have only SLP loudmouth axle backs and the remainder is stock but was considering long tube headers.

Would these http://www.brenspeed.com/20546.html work with my exhaust setup or would I HAVE to buy another mid pipe?

I don't know if shorties would give the same flow/hp gains and my smog legal status goes out the door in less than a month... soooooooo


least expensive long tubes and/or shorties that will give some decent gains?

 

Those aren't quite full length headers, and yes, you will need a new midpipe with them.

OBX is probably the least expensive route, and comes with a mid-pipe.

 

i would go with OBX. i have some rubbing on the frame, but i got it to back off. probably my fault. the only issue i really had was with the sealing around the collectors and midpipe. the clamps they send suck. its a cheap fix though. i could not imagine spending over $1000 for headers. i got mine for $450 with 2 midpipes

 

where did you order them from and what's the quality of OBX? don't they make cheap import parts like pedals and shift *****?

 

Someone's got the mod bug...

 

I got the OBX's on flebay, $450 shipped.

 

Longtubes will give you a considerably larger gain than shorties, as shorties give little to no gain and all. For the longtubes you linked, you will need a new mid-pipe, and you could be able to fit a Mac Prochamber with those LT's

 

I think it's the "While I'm dyno tuneing at 400$, why not get the most out of that session" kinda frame of mind.

I will probably have this setup for another couple years so why not...

 

long tubes make more power in the lower rpm range while the shorties work better in the upper rpm's

 

That sounds backwards... shorties for low end, long tubes for top end.

dunno page two the long and short of it. Of course the tests wern't done on our cars but the end results would be the same.

 

=top end power, bottom end loss

 

I have 1 5/8'' JBA LT's and did not feel any loss down low what-so-ever. From my buddies and a few of the guys in POTR, don't expect to feel any gains from the the shorties. Most guys buy ceramic shorties for engine appearance to get rid of the rusty stock manifolds.

 

That's with a change in the diameter of the primaries, not with the length of them. From the same article, and the blurb next to the one you quoted...

"The shorter primary pipe length generally sacrifices some torque on the bottom of the torque curve as evidenced by our test. This was followed by an increase of over 20 peak horsepower at the top end of the power curve."

And from the article "Auto Exhaust Science":

"Dyno tests with headers having primary lengths adjustable in three-inch increments show that lengths between 24 and 36 inches have only a minor effect on the power curve of V-8s that you and I can typically afford, although the longer pipes do marginally favor the low end."

Emphasis mine. So, Long Tubes get better low end torque according to both these guys.

 

I've run my BBK's for 11k miles with no complaints

 

Robert it looks like you car would pull one way or the other from that picture.

 

Haha thanks man, it may have some slight modifications

 

No need to justify anything to me...fellow modaholic here.
