435i convertible (F33) M sport, want M4 rear conversion

billybeartku · 09-23-2015, 11:38 AM

hello everyone.

Im a total newbie on this forum so please forgive me if this is a stupid question.

This will be my very very first BMW that I own in my life so im super excited, I've always wanted 335 coupe before but wasn't financially ready for it. But now i am so decided to just get the 435i convertible.

Anyway, my question is:

I want to change my rear to look like M4 (i think you guys call it M4 conversion?), so I need to add diffuser and make it quad tip. But I don't know what brand I can use to achieve that. Do I just change the tip? or I have to change the entire down pipe or whatever? Also I was told by my friend that the system used for 435i coupe isn't fullly compatible with 435i convertible. Is it true?

Thanks everyone for your time and answering my noobie question.

Much appreciated.

Im just into modification status to turn my 435i origin double tips into a quad tip muffler with diffusor change and resonator.
I choosed Bastuck for this mod, caused by pricing and legality into Germany.
But thats surely no M4 conversion at the rear imo

Forgive me my n00b question but the 435 conv. is cheaper than a 335??
