Can you let us know what the whole process is like?

did you feel the lost of low end torque compared to OEM exhuast? i've been thinking about this 1.5 years.

Perhaps the removal of mid-cat increase more flow? so you dont feel the loss of power?

If you can find a full OEM exhaust, it probably is cheaper to get all the heat shields, mounting brackets, trunk tray and bumper than to have a custom exhaust made.

As stated previously, M pack equipped car in europe come from the factory equipped with the M badge. This is not posing as it does not say it is an M3, Simply stating the vehicles status as an Mtec upgraded car.

I wanted to do this to my car but it would involve moving the whole trunk and gas tank which my muffler shop (welder) place did not want to touch . Especially involving with gas and fuel.

Actually the fuel tank is not touched w/ this mod. The vapor canister must be relocated.

I've been going back and forth about going to a 335 type exhaust. From what I've been able to determine the obvious changes are:

- Heat shield and bracket in front of the rear axle (to accommodate the right side exhaust pipe).
- Trunk storage well and heat shields (335 uses 2 shields).
- Exhaust hangers, passenger side.
- Vapor canister vent pipes (one from the fuel tank and one from the filler neck)
- Rear bumper fascia with two cutouts.

The 335 uses the same vapor canister which is bolted to the trunk storage well on my 328. What I can't figure out is when the well is changed where is the canister mounted? If anyone has pictures/diagrams of the 335 setup, I'd like to see them. TIA.

So let me get this straight: you bought a 325, but you really wanted a 335, uh, I mean, you really really wanted an M3, so you Frankensteined them all together. Why not just buy a 335? And why pretend it's an M3 when it's not? Oh well. Looks like nice work, and it's your car, so whatever makes you happy. Enjoy!
