E36 exhaust

[stracer]

I have been looking around at exhaust. I see a bunch on ebay(Good shit, lol) anyways are all catback systems campatible between 323, 325 and 328?

[SHAHAB323IS]

as far as i know, yes

[97alpineM3]

Yes... they will.

stick to brand names.

Isn't the 323 different from the 325 and 328? Single pipe instead of dual pipes?

BTW, there are brand names on Ebay from time to time. Just be careful, some will give you a brand name. If you read the fine print, it will "brandname like" and its not really a known quantity. And, according to some other sites, the 323 IS different from the 325 and 328. Which auto do you have?

[stracer]

I thought too that the 323is had a single pipe and not duals after the cat. Thats why I was asking the question.

[SHAHAB323IS]

it does have a single pipe, i never thought about that, so no....

Bavauto, and I think Active Autowerks, has cat-backs for the 323. Maybe others. I wonder if you could take a 325 system, cut and weld a 2-into-1 back section to match the single mid-pipe? Would the other hanger points match up?

I recomend an eisemann exhaust, look into it at mmotorwerks.com

[bitcore]

yes, single Y pipe to the cat.

You will gat a crapload of power from the increased flow. The 325's and 328's only gain around 5 hp with exhaust, but if you open up the intake and get a decent exhaust, expect very very noticeable gains. becuase of the ODBII specifications, they restricted the hell out of the 98+ motors, so they label the car as a 323 even though it does have 2.5L of displacement.

Yeah ditto, there arent many companies who have them.

A good muffler shop could probably build you an exhaust W/ Flowmaster/ Magnaflow. I don't how much it would cost or how it would sound.

[stracer]

I was thinking about a custom exhaust.

Get an original M3 exhaust, all the way from front to back.. gives you an awesome sound and 15-20HP gain

[///M Power]

No, no it doesnt. The M3 exhaust gives no gains on your car. It's purely for a SLIGHTLY louder and deeper tone. It really is more of a disadvantage because it weighs nearly 50 lbs.
