Fitting a M3 rear silencer

[Westkite]

Hey

Are there any of you that know if a stock E36 M3 rear silencer will fit up underneath on an E36 compact (323Ti).

Will there be space between the bumper and the rear wheel? I know that there have to be made some piping and a new holder for the silencer itself.

The reason for wanting to use a M3 silencer is that almost all sports exhaust are noisy. I just want to have the deeper sound that comes from the M3 silencer and be sure that the stock 323Ti silencer will not be the limiting factor for slightly tuned engine.

Anybody that knows?

I'm pretty sure that the M3 rear section has a dual inlet while the 323ti only has a single inlet. Besides that, you'd have to shorten it to make it fit. A common upgrade for 323 guys is to install an M3 MID section(catalytic converters). This will give you a little bump in horse power and they bolt right up with no modifications.

So in short, an M3 silencer will need to be modified to fit and if you're going to do that, then you should upgrade to an M3 midsection as well.

M3 mid section is an excellent idea. The muffler section will require several modifications to work.

Piping needs to be shortened
Muffler will need to have a couple dents installed (big hammer works best) to clear.
Rear bumper will need to be modified to go from one outlet to two.

I suspect that a bigger factor in the quality of the sound produced is the M3 engine?

There is no replacement for displacement.................

when i talked to a guy at bimmerfest about that who was selling mufflers, he said it wouldn't fit a TI

I've cut mufflers apart with a band saw, shortened them and welded them back together. Its not real hard just takes fiddling to get everything to fit back together.

I'd probably stick to a single tail pipe just because the 4 cyl is going to get buzzy with a twin pipe modded stock unit. On the other hand the E46 muffler has a valve in one of the tail pipes so its quiet at idle and opens up when you hit the gas. (At least mine does...) Has a nice grumble when you step on it hard. Looking through the muffler with a flashlight it looks like the normal pipe is a baffled pipe and the valved pipe is more like a typical glasspack.

It's a 323ti

OOPS, 6 cyl ,,Well then the 330xi muffler would rock if you could fit it in there...

It has a nice growl when the secondary pipe opens...
