95 m3 exhaust on 94 325is?

[okczy21]

will it directly bolt-up? what gains will i notice in power and sound? I also purchased a OBX header for it, will this be a nice setup?

Are you 325is1994 on BMW-forums.com? I saw the same question posted there also. Both seem to be pretty good boards. They move a little slow though.

it will bolt straight up. although i would go for a full custom exhaust system since you have a header. i am running no cats and the car just screams!

 

[okczy21]

no cats huh, thats what i wanna do instead replacing my cat, can i run no cats with the m3 exhaust, what did you buy to replace the cats

 

[frolf]

no cats HUHHHHH

and how are your 02 sensors doing

 

[okczy21]

do the 02 sensors plug into the cats

do the 02 sensors plug into the cats

Ignore frolf he's been stairing at the xbox all day. OBD2 has 4 o2 sensors which there is 2 behind the cat's, but obd1 (94) only has 1. It's all good.

dan i removed my o2s and no CEL.

Obx header. How is it like 250 bucks or less on ebay? Are they crappy headers? I was looking at other headers and they run for 700 plus. Please explain.

it should bolt right up. There are several companies that carry aftermarket resonators to replace your cats. I have the AA Track pipe on my M3. The post o2 semsors are simulators, so the ecu thinks that the "cats" are doing their job of filtering the emissions. I am very happy with the results.

You dont need O2 sensors. <_<

hello, I have a 328 and I just got an M3 exhaust for my car. I was under the impression that you need to get the mid pipes from an m3 or 328 if you have a 325 althought I may be wrong.
good luck!
