Asking Price:

USD 450.00

Item Interest

Selling my H&R Springs $150 + shipping

Selling a new Catless Downpipe only fits X4 M40i not X3 35i or X4 35i (those are PWG and use a smaller diameter)

The downpipe quality is amazing full 4" when compared to a friends similar engine pipe from another manufacturer his was so skinny it explained why my car sounded so much better. Couple of friends with X4 M40i already running this prototype as well that CTS Turbo & I worked to tweak for our cars.

Any Questions PM

Hey FSociety!

I have followed your build on here since I got my car in October. Have some questions about it if you wouldn't mind giving some insight. Any particular reason for going away from your X4? I used to have a 2008 535i with FBO which ended up putting about 430 to the wheels. Interested in seeing how I can get close to that with the X4 M40i. I have a 2018 one.

Look forward to hearing from you.

Lease is up next month, I actually took over an M3 for 18 months but been missing my X4 M40i since I gave the lease to someone else over the summer.

Your 2018 X4 M40i is also N55 correct? It's an amazing mid-size sport activity coupe

I can't wait for new X4M for 2020

Yes, it is the same. Did you ever dyno your car?

I did, on stock, jb4 and beta BM3 OTS.
But I decided to do 1/4 mile, 0-60 test via Dragy Performance Meter instead and basically shows me more real world.

0-60 4.19s
1/4 mile 12.4 @ 110mph on BM3 93 OTS

I was also able to test the BM3 93 OTS targets 15.7psi boost vs MHD STG2+ targets higher boost in another X4 M40i was running that map and my car always took the win regardless of the pull. It showed the efficiency of power band and intercooler definitely helps on back to back pull.

I didn't get to test the E30 OTS maps but in real world scenario Mexico proved even more powerful all around.
