Using E36 Exhaust

[SamE30e]

Hey,

Has anyone used the E36 exhaust with the raceland (Superspring replica) long tube headers?

What's required?
Do the hangers line up?
Where do you shorten?

I have this picture, which I think is a 325i exhaust.

Maybe the obd 1 exhausts are different, but long tube headers+obd II exhaust doesnot fit properly. In thecase of obd II, although it could be used, the e36 exhaust will require it to be lengthened before the cats and shortened just before the muffler. The flanges will have to be cut off and relocated to just before that first 45 degree bend

Hmmm, would it be easier to weld up a E30 325i exhaust?

And I'm from Mississauga.

Here's how mine fit with OBD2 manifolds. I later switched to euro headers and just needed to cut another foot or so off the midpipes. Wasn't too difficult. OBD2 mids are better than OBD1.

I used the OBDI cats into an E36 M3 Remus Cat Back.

Here are a couple of videos so you can hear how it sounds. The first is on the street the second is autocrossing.

Heh, I've got the same exact setup :)

I think your coding plug is wrong though...noticed your idle is like 1.5k.

Yeah, I don't like how that brace isn't able to fit though. I'm thinking an E30 i exhaust. But I don't know how much room I have to play with to connect it at the front pipes.

Damn that looks like it was jammed up there high, lots of ground clearance, do you notice any loss in rigidity of the body without the middle cross brace?

It is way up there. It's on my list to fit the brace in there, I haven't noticed a difference, but I have a front subframe x-brace, too.

Eventually I want a track pipe just to save weight. I'm guessing a 2 into 1 merge after the headers with a single 2 1/2 all the way back would save around 40lbs.

The OBD2 stuff is HEAVY!

Had a thought,

Could you move the entire center section further back past the cross brace and then fab up from the cats forward? The entrance to the cats would start right near the between the rear seat foot well and front frame rail.

Obviously the rear section would have to be changed and mated as well.

at that point the cats would not be getting all that hot and would become ineffective.

Yea, i saw this as a potential issue as well... oh well.

Why is that? As far as I knew, OBD2 midpipes are dual walled and have a smaller inner diameter.

They are dual walled, but the inner diameter is the same or larger than the OBD1 version, and they don't have that nasty little merge going into the catalyst.

Whatever the size (bigger is not always better) they definitely flow better than OBD1 midpipes.
