Shorty VS Long Tube

[krahooligan]

What is the main difference between Shorty and Long Tube headers?
ive never installed headers on a car and Long tubes seem to be the most popular. Why is this? thanks guys.

On the GT's the factory manifolds are pretty much already shorty headers. There's virtually no gains to be made with aftermarket shortys. Long tubes are pretty much the only way to go.

The real restriction of the neck down to 2.25" between the cats and midpipe resonator. Getting rid of that will be more useful

What I never understood is if long tubes require deleting cats. That isn't an option to me (pro-environment and stuff).

Pro environment and driving a gt? More like, "I like the environment, but really I like power and going fast". I personally like the idea of the environment but care more about melting tires and going triple digits.

you can get high flow cats.

You cannot reuse the stock cats with out relocating and welding them, and as mentioned above, high-flow cats are also a choice.

However if you are truly environmentally conscious and you want to maintain emissions integrity, you cannot use high-flow cats or relocate the stock cats. The catalytic converters are placed in the optimal location in the exhaust system to best allow them to burn off all the hazardous wastes created by the combustion reaction.

Also, aftermarket cats are not made of the same materials as the oem cats and do not do a proper job of eliminating the toxic gases.

thanks for the information man. high flow cats are not smog legal here in California so i would not run them. only thing im worried about is the smell and being ungodly loud and getting a ticket and having to fix it after all the work i put into it

I live in Cali as well!

Good thing is that we don't have to worry about smog for 6 years after purchase. I was a little worried about sound being too loud since I have a Corsa X exhaust, so I'm going with catted headers.

I highly doubt you'll get a ticket for the aftermarket headers, unless you go with off-road and a cop knows where the cats are.

I like my chances

Long tubes change the flow which will allow more power and trq. The collection location is the key item in long tubes as well. With a larger tubing, it free's up the flow which again allows more power. Most gains are around 30hp or so. Shortys are just factory replacements but with 1 of the cats built into the exhaust manifold, you cannot do that without a custom mid pipe.

If the environment is something of mind... buy a 4 cylinder sentra or something. I wont say hybrid because those things are actually horrible.

Theres reeeeeeeally not a big difference between having catted headers and off roads with our corsa catbacks... I'm telling you from personal experience... and if you dont believe me you can ask DEZL50. I can hear him at cruising speeds. no catted long tube will save you here in CA... the only question is, do you really give a f***... I DON'T!!!!
