I got my brand new F30 several days ago..already started upgrading it with BMW M Performance parts (which is not so easy here in Norway!)
Question: does anyone have experience with the insidePerformance 335i style exhaust and diffusor for my car (328i)? I know they built realy great stuff and quality (frind of mine in the neighbour-town has one of their exhausts on hin 135i).
I like that more aggressive look of the 335i back - and they offer an plug and play conversion kit to that look for all models:
Note that this blue BMW F31 is a 328i! No 335i!
They also have their own diffusor which is quiet similar to the BMW M Performance diffusor - but looks a bit more powerfull in my eyes - because the middle black part is not only limitted to the center area - but surrounds also the exhaust tips.. what do you think:
compared to the original BMW m performance diffusor:
But even more interesting: does anyone have any experiences with this product? Or even had his car on a dyno after installation? Ther dyno diagramm looks very good - but as always one of an independant customer would be much more interesting ;o)
Thanx for your opinion and help!
