Headers

[DrMus]

Can someone please direct me to a good thread regarding the various header/exhaust choices for my VT dedicated LS1 track car? I've done some searching but can't see the trees for the forest. I don't understand the performance difference between tri-ys, 4 into 1, long, short etc.

For ls1 I'd just get some 1 3/4 inch 4 into 1 ceramic coated can't really go wrong with that

I would give Terry at MCE Motorsport a call he is very good with off the shelf OR custom headers and works on a number of race cars.

Mate what are the performance properties of the 4 into 1 vs tri y and what does long vs short do?

4into1's will give a better top end. I would say for a track car go 4into1's long. You will always be up around higher revs on the track so Botton end power is not so important (tri y's sometings better down low) but even that's debatable.

Have a read of this old thread mate.
