Re-used Exhaust center sections

[andy]

Howdy all,

Has anyone tried taking the center section from an e36 M3 for example and just cutting that to fit under the ti? We're finally making some good progress on my swap, have some nice headers and are looking for options for plugging it in.

I have m3 midsection, which includes headers cats and resonators. It bolted in. I'm 99.99% sure. The muffler section didn't fit though.

That's good news - So I just need a muffler that fits and we're set there.

you can use an e46 330 rogue engineering muffler, needs minor work to fit IIRC. OR go my route. I used a small magnaflow 2.5" dual/dual universal muffler. If you go my route, get resonators. I'm awaiting to put a set in, because the lower RPMs sound like ****

RE or anything nice is out of my budget for the time being. I did think about z3 mufflers, but I realized the i6 z3 muffler is only 1 pipe; the M3 has two. Oops.

Does anyone know if a M Coupe/Roadster cat-midsection will work on for a 318ti swap?
Going to be using a Supersprint Z3 3.0L muffler.

M3 Mid-pipe:


The mid-pipe fits perfectly under the car with no modifications. Its the rear that's the major problem. As a solution, I got ahold of a new 325 catback (thanks again 96Cali). As you can probably guess its a little long, hence the two pieces:



Hmm, two pipes on the mid-pipe and only one on the cat-back? I believe this part has made an appearance on the site before, just not on a car:



Since I already have a motor swap ti lying around I'm getting this installed onto the 325ti tomorrow. Then it comes right back off of course. This way the hardest part will already be done.

Keeping my fingers crossed on a chassis deal... Stay tuned.

It fits perfectly in the bumper and looks fairly stock (The 325ti bumper has been trimmed already to accomodate a dual tip. This will work perfectly with the new unmolested bumper. Time to go take it off the car.

I have the centre piece off a 325, it bolts striaght on, and i also bought a scorpion stainless backbox from the same guy, it was a twin inlet to a twin oulet , i bolted iton and it stuck out the bumper about a foot, so basically all i did to make it fit was slice the tips of the centre pipe to get rid of that ridge, shortened the backbox pipes 170mm and it slid on nicely andi just secured it with 2 u-clamps, and just mounted the box with a few bolts going into the floor of the boot.. if you want pictures just give us a shout.

pics please, i may be doing a 6cyl swap for my 318ti track car, later this year

heres the stainless box made by scorpion ( in my opinion sounds better than the others, its quiet and has a gorgeous rasp to it when you apply the accelerator, and has a nice deep powerful growl on idle, turns alot of heads and sounds perfect with the Induction kit.

heres a couple more of underneath









Ignore the dodgy cutout on the bumper... its embarrasing but ill have the mtech bumper on shortly, correctly cut out...
