BMW M140i with M Performance Exhaust.

So as some of you will know we have experienced the dreaded exhaust rattle on our original back box and it's replacement.

Well finally I have some good news, BMW resolved the problem by fitting a valveless system on to our car and I am delighted to say that our BMW M140i now has the BMW M Performance Exhaust fitted.

Initial impressions of the M Performance Exhaust are that the overrun is much more active, there is a change in exhaust tone generally and there is an improvement from within the cabin (which was the main reason I wanted one anyway!).

I am very happy with this result and now we just need to get some miles under the M Performance Exhausts belt to build up some carbon and see what it really can do.

Any questions leave them below and as always please subscribe to the channel for plenty more content to come.

Cheers
Stephen
