clamps are temporary until i drive it a few days.
o2 hanging there is only for stoich meter.

Your collector could use some work. There's nothing wrong with clamps, also.
As for size, 3" is probably OK for a 300hp + euro motor. Run the motor's details through at www.headerdesign.com and it'll give you a better idea.Comment

thanks for the tip. what would make a better collector? i will check with header design.

the collector is dual 2"id (almost exact matching the headers) going to a spread oval. its a little tough to see in the pic, but both "primaries" just barely touch and are cut off at 90 degrees....about 2" inside the ovaled collector. that metal v-shape on the outside was just to cover the back side of the collector.

It's not hard to determine the optimal solution... www.headerdesign.com will get you started.
They must be having trouble with the site, I tried to reg yesterday and today and it doesn't seem to be working.
Anyway, I'm guessing that they run a simulation?
What do they use for inputs?Comment

You can probably ask a good welder to modify it with some mandrel pieces to make it fit nice.
How is the project going D ?Comment

i tried to get the guy in exhaust shop to use the stock e36m3 catback in it's original state on mine. He basically said the piping angles are just way different, so we ended up just cutting pipes off and doing a custom one all the way to the muff.

It's going good man! Everything is ready, I've bought all new sensors/seals etc, everything is in, just need to modify the wiring harness, send the injectors for flowmatching/rebuild, and buy a new UUC flywheel and M5 clutch, a rad and maybe, beyond that all I can think of is the OBDI fuel rail and 318 harness cover, everything else is covered, even have an M3 cluster with 49k on it. Once all that is in, the exhaust is the last step. I have THR arms and with some subframe reinforcements for the subframe, I won't need any fucking around with the stock downpipes so I'll just get stock E36 cats. Beyond that, I'm not sure. I really REALLY like this dual muffler, straight through exhaust from UUC but it's a solid waste of $ to have to cut the pipes off and pay an exhaust monkey to do a new pair.
I'm in no rush, the car is wicked fast in the turns and I'm not racing so I don't care how many ricers fly past me in the straights. I'm learning a lot about the car and so is Felicia. One more track day in May, maybe one more in July but I'll probably put it in in time for July.Comment

good news!
what subframe reinforcements are you talking about?
people succeded in massaging stock e36 exhaust into e30, but honestly, i would strongly advise to bite the bullet and make a full custom mandrel exhaust in a good exhaust shop - otherwise it might end up being a big pain in the ass.Comment

Alex: I'm talking about the motor mount hardpoints in the subframe crossmember - weak.
Thanks!!

in regards to changing the piping upstream from the catback flange, i wouldn't imagine there be too much wiggle room to move the cat pipe around as the tunnel is already pretty restrictive (can do perhaps 3" in each side latterally but not more i imagine)
maybe someone can post pics of Mpressive's setup?Comment
