Interested in Shorty Headers?

^ x2 and the cheaper cost is appealing

So what is the driving factor to a shorty header, easier install or cost?

Can we have both?

When it comes to install, how high does the engine have to be lifted? And what parts have to be cleared to make them fit?

I agree with sky n Dan. But the discussion ended last time with some question as to the gains available with shortys. So I would be concerned about stating cost as a driving factor if that would reduce performance gains.

OK. I revisited all the previous discussion. I want performance gains that will pass emissions test. That's it.

Jason has said that the low end torque gains may not be great (compared to LTs) but that won't deter me. I would also opt for coating if it will help.

Someone just buy 25 and sell the other 24

As for low end torque, running 411 gears and 6 speed transmission you aint going to see the difference, you will see it on a dyno. Adding shorty headers to the 2v engine will clean it up tremendously. If this was a 3v or a 4v motor you would need the LTs for sure.

Shorty header pro's..
No need for a tune to cancel out back O2's
Will not cause drone...
Can pass any state emission testing
can add up to 15+20hp and +25 Tq( more if you polish the exhaust ports when installing)
Cost is less...( no need for aftermarket cats)
Hook to factory cats...
No problems with warranty...

Shorty Con's..
Less hp and less Tq than long tube headers( LT's can add up to +30hp and +35 Tq)

oops I forgot that one.. ha ha ha

with my LT I didn't cancel out back O2's until I took out the cat's then I just did. I have no idea if I actually would have had to or not.

Thanks for posting this. I re-read my post and it did not reflect my enthusiasm for shortys. I intend to do what ever I can to be in on this. I want them. As long as I'm stuck here, it's the best I can do.
