I wanna do a exhaust upgrade any recommend ?

Meanly to improve the sound not consider to much about performance( I know just do the exhaust work can't improve a lot performance).

Any brand recommend?

I really like GThaus 4x90mm one but a little bit over price……

BTW: My car is 428xi m-sport.

thanks guys !!

you have for axle back: Eisnmann, Active autowerke and Remus
for cat back: AFE, Magnaflow, Borla, IPE and Meisterschaft which is the best in my opinion not all make power gains but they are defiantly sound better than stock, I have the AA axle back with AFE dp and it sounds really good.

I don't know about the labor where you live but here the mechanic installed springs, dp, muffler, wheel spacer and full exhaust wrap for $100 super cheap lol, as for sound it was loud at first before the wrap then it got quiter from carbon i think but again if you found it too loud for your style wrap the exhaust.

that labor was $100 in Cairo! In the US, you're looking at around $500 for all those mods at the cheapest. Labor isn't cheap!

I recommend the M Performance exhaust! Has a nice sound to it and no drone. Got mine installed by the dealer for about $125.
