Short OR Long headers

[97Trans_AM]

every one on this site has told me to go with long headers, but when i went to the local speed shop the dude told me that the Trans AM and Mustang are made to have short headers. Keep in mind this will be my frist mod so i wanna make the exhust improve my low end not my top.

Shorties really aren't worth anything over stock. There are also mid length headers available, which will make a little power over stock. Long tubes will make the most power though.

just another shop dude that doesnt know what he's talking about just trying to sell what he has in stock

Who's to say what type of part was made for what car?
That guy's an idiot. Go with longtubes and don't worry about it.

Ditto.

dont long tubes mess with the cat converter so my car wont pass inspection

[jag42420]

Your stock cats won't work with LTs, but you can put high flow aftermarkets on there to keep it legal and pass emissions.

Ditto. Get LTs and high flow cats if you must. Don't look back. The LS1 responds very well to LTs.

Go with Long Tubes, you won't regret it.

Shorties aren't worth wasting your time, the stock manifolds are practically shorties.

Go with long tubes you will see a lot more torque than shorty or mid headers. You can install 02 simulators if you dont want to put cats back on your car, so you can pass smog

but do long lubes help my low end or my top

[jag42420]

Generally both, as they have less backpressure than manifolds. You'll notice the gains in the upper RPMs. You really won't feel much of a gain in the lower RPMs.

Here's a pretty decent header article. It doesn't really explain what the headers will do for you, but show variances in power produced by various header sizes: http://www.carcraft.com/techarticles...e_header_test/

All you guys on the other side of the country are lucky bastards!

Here in CA, emissions are a thorn in our sides. The last 2 times I've gone for smog check, one of the first thing those guys do is look under my car (2 C if I've replaced the headers with long-tubes.) What a bunch of Haters!!

[nitroushane]

That sucks for you. I dont even have to smog my car. You got to love living by a small town.

[jag42420]

In Kentucky, they don't care what you do with your exhaust. I passed an out of state title transfer inspection on a '79 Z28 with headers and turndowns. Probably 3/4 of the cars here would fail an emissions test.

[cobrahunter]

Alright, alright, all you haters!

Yeah, I know some guys around here are able to find someone who'll take cash to look the other way, but I haven't found one yet. At least, that's the ONLY mod I can't have. Would be nice though.

but do long lubes help my low end or my top

Both, but what size you get, length, collector length etc. is what determine's low and top end. Bottom line, Long tubes out perform in everyway compared to shorties and mid's.

so if im looking for long tubes that will help my low end what am i looking 4 short or long collector length?

Not true. I used the stock cats in a header Y-pipe before and they worked well. You just have to work at getting them welded in there...
