IMHO, 3D design's diffuser are really expensive. And if you accidently crack it while reversing onto something, you're doomedddd!


I'm currently driving a 28i. Couldn't find any companies that makes the exhaust for the z4 with the N20 engines so i decided to go custom for the meantime.

Since it was a bolt right after that cats, decided to fabricate a bolt on straight pipe to a custom muffler box. No loss in low end as i've already tuned it up..
A little bit droney on highway drives but you can't really hear it with the top down. A lot of backfiring when downshifting.
Not really noticable in the video though hahahaa

Did quads hmm:
