For Sale: 2001-2006 BMW E46 M3 custom "Euro" catted section 1

[Gt4]

I am selling an OEM section 1 with catalytic converters for 2001-2006 BMW E46 M3.

It was a super low mileage OEM 2006-2008 BMW Z4M section 1 that I modified to fit E46 M3. Length and flanges orientation was different so weld it to fit E46 M3. Also add O2 sensors bungs and an EGT bung.

Now it's basically the same as E46 M3 Euro section 1 but less restrictive cats

Price: $1600usd shipping included

Were the cats cut from a new OEM header?

No, this is a low mileage modified OEM Z4M section 1. Z4M have cats in headers like E46 M3 and also 2 more in section 1

Did you run it at all? Fits perfect? This would be a good alternative to running aftermarket high flow cats with euro headers.

Just finished welding it. Not the first time I did this mod, did 5-6 similar in the past

Clever way to shorten the pipes!

I have an E46 euro set that I need to do the opposite to, to fit my Z4M

Yeah I have an expander so it slide in 3" and doesn't affect the flow, no weld the goes thru the pipes.

Why you want to do the opposite?? Just add o2 sensors and EGT bungs to an OEM Z4M section 1. Way easier! I did a couple for guys in Zpost 10-14 years ago.
