Bmw's Suck

HA! Now that i have your attention ANSWER MY QUESTION:

Ive been having a discussion with someone on the board via PM but he isnt very clear. It is my understanding that 325 and 323 share an engine, but 323 have more limting parts (ie exuast is one pipe). I was trying to figure out that if i took the headders and cats of a 325, that i could use an aftermarket 325 exuast, which are more easy to find, and put them on my car making it virtually a 325. Any one care to correct/help me?
Were 325s not made past 95 or something? I just cant figure it out.

in 96 the emission laws caused bmw to use bigger engines in their cars to produce the same or more power from the predecessor. this caused them to make the 328 instead of the 325, but still keep the 318. in 98 though they made the 323 which was like the 325 in that it had the same engine but was more restricted.

so to answer your questions, i would have to say no
i think you would need more then the "free flow" exhaust of the 325i to make yours like a 325i. im thinking you would need to do something to the intake and maybe even to the extent of doing stuff to your head, i.e valves cams etc. perhaps a whole obd1 conversion too might be needed.

thats what i think though so i may be wrong.

The 323 is supposed to be like the older 325 engine. Does your engine have the twin exhaust manifolds? How about oxygen sensors? The old 325 had one. Don't you have four? You may could use the center section off the 328. As I understand it, the 328 is just a larger 325. I am sure it could work with some research.

325's are all obd11 the 323 made in 98 and 99 is an obd2 version of the 325

how does that work? They cant both be the same diognostics then one be a verson of the other.

I thought you owned/drove a 323 ligitmately as your car so I valued your opinon, but since you dont have your lisence yet, your just a boy who probably doesnt know what hes talking about. I researched and called a BMW parts place and asked them, they explained it the right way, and I was more correct than I thought. Thank you for your time but you led me astray.
