A friend of mine has an 89 LX. He has all new mac exhaust with a Mac H pipe (NO cats at all) with shorty headers. I asked him why he won't put long tube headers on and he said it's because he'd have to get rid of the H pipe and he'd lose power. My question is, would he have more, less or the same power with long tubes and straight pipes, or shortys and the Mac H pipe?

more power with long tubes and straight pipe.

and he could have his h-pipe with the long tubes, he'd just have to do a bit of work cutting the h-pipe to the right length and stuff.

im pretty sure he could at least.

wow i actually agree w/ this canadian ehh?

maybe a few more ponies on the top of his power band, but a VERY NOTICABLE drop it torque, it's not even funny how much torque you lose on a nearly stock 5.0 with just straight pipes. I would not reccomend it if he is near stock or pushing under 400 h.p.

ok i need some sort of a theory behind this.

long tubes/straight pipe = way less backpressure.

how does this = loss in torque?

im not saying i dont believe you or anything, id just like someone to explain how this is possible to me.

thanks.

because, at least i think that it would be too much

jus like a 90mm TB on a stock car

i guess that would be an example

ya i didnt read the straight piping part..i renounce my in agreement statement

boss429

lol nice try amigo

but im kind of looking for a better explanation then "its too much"

i give you an A+ for effort though

Stevens91gt

yesss!!!! well for further explanation..

well you see, the hypotenuse of the vertices is equal to tangent

therefore cosine is delta pi positive and henceforth straight piping = loss of backpressure aka loss of torque

boss429

wow, it all makes perfect sense now.

come to think about it, i dont know how i didnt realize that myself.

wow i feel like an idiot. [:@]

hahaha

lol ya man i mean its easy biology
