///M5 exhaust system in a f10 523i

[K_S]

for sound and performance a downpipe would have been better... if anything, if you use the larger M5 piping, you gonna loose power and back pressure... but its your car, as long as you are happy...

Eat beans - back pressure sorted! :smilebounce:

well done to the OP for being creative.

End of the day its your car - you can customize it in any way you feel!

Now you've got me thinking. Wonder if I can stick a 335i back box and tips on my 135i coupe without destroying what's left of my motor plan.
