E46 M3 Decat pipes fit Z4M?

Post by bmwaddict » Thu Jun 29, 2017 10:25 pm

I've been after some decat pipes for a while, they rarely seem to come up and at around £400 for a new set from Superprint and similar it's a bit steep for what is essentially 2 straight 2ft lengths of exhaust pipe. Lots come up for the m3 and they look identical, does anyone know if they fit the z4m? I know the back boxes are totally different, but the decat pipes fit before the x pipe (section 2) and as it's from the same engine I'm hoping they fit and I can save myself about £300 quid! (maybe wishful thinking I know). T.I.A.

I've no idea but I imagine the m3 ones to be longer?

they wont fit as the flanges are in the wrong orientation for the z4m..... how annoying :headbang: :headbang: :headbang:

easy fix for a decent welder however.

A custom exhaust manufacturer could do them a lot cheaper than that.

My little blue zed is in lots of bits. With lots of things started and not many finished! I may have found the limits of my time and ability!!

What is the main difference fitting these decat pipes, noise or performance, i take it you remove the cats and fit these pipes in their place, any sound files out there?👍

Probably more noise than performance but they do sound good! 8)

They drop a little performance below 3k, but then makes it up and adds some over 3k. You'll need a tune unless you can live with a CEL.
