X PIPE?

[st3althbeam328i]

So my question is, Is it worth it? I've never seen it done to a E36, but I hear you get more power out of it rather than a straight pipe (which is what I have right now). Any input would help thanks!

nothing that has a bend will ever increase power. You might see the power curve change a bit, but the straighter the exhaust, the more power...99.9% of the time.

That's what I figured. I did my research after I posted this and came to find out that this is a better mod for the V8 applications than the I6. Thanks for the tip

x-pipes help alot when you have headers. or anything that has 2 banks. It helps equal out pressure.

[st3althbeam328i]

yeah I figured this out thanks for the help guys Its best when you have a V8 for the Xpipe for full funtionality

That's why straight pipes are pretty common. Not zig zag pipes. :p

A mate of mine with an E36 325i got an X Pipe put in his car and it made a pretty big improvement to how the car drove.

There was a significant increase in low end pull and the engine seemed a lot more free-reving.

HMM This is what i've been hearing, but I wasn't sure if it would be a significant difference for the I6. I always hear of the V8 guys saying this is a great upgrade

You can't put an x-pipe on a I6.... on a v8, the headers are on opposite sides of the car, and the x-pipe connects them before the go out the back. BMW headers are on the same side of the car and are already connected. Theres nothing to x.

x-pipes are a means of equalizing the pressure on both sides of a V engines exhaust... in a mustang u usually wanna do it as close to the front as physically possible... the only reason that they use x pipes more often than just a straight tube connecting the two pipes (H pipe, if u will) is because the angle at which the flow enters and exits the flow produces less head loss.

not necessary in an inline engine for most applications...

in the mustang i used to have the pipes were not the same length at both sides i dunno how but one came up a couple of inches shorter than the other... the x pipes provide the same (theoretically) physical conditions for the flow out of both banks on the engine

Sorry I was refering to this...



Its probably better to call it an X-Merge

[MIKEGTR]

that is an x pipe


u don't need it

[loonibab///m3]

I think xpipes rae good for big motors like v8s and up.. but on a 6 banger I wouldn't worry about messing with an xpipe, straight pipes ftw.

that is an x-pipe. Like Mike said, you don't need it... it isn't going to help you make power.

Waste of money
