I understand what your saying and Im not into trying to make my car look like something its not, but the standard exhaust lets down the back of the car and must go, and if its getting changed may as well be for something i really like.
I usually go for subtle mods, and may well end up with a similar set up to marks but if the quads are possible then that is an option i'll also be looking at.
cheers for your input
fair do's mate, it wasn't a dig. I reckon you'd be better off with a custom one rather than a M3 backbox modified to fit. because it has 2 entries and you have only one you cant just block off one of them as it wouldnt flow properly.
Still wondering if anybody knows if I did manage to pull it off and fit a standard m3 exhaust onto my system, should i expect this to have any impact on the my engines performance, giving that it would be a m3 petrol rear box on a 320d engine.
sorry, what i mean is that the inlet from the left runs the length of the silencer internally and exits on the right, and vice versa for the otherside. So if you sealed one side off you're gonna have a load of extra metal and weight at the back of your car thats only for show.
so if I split the exsisting single pipe into 2 so it has 1 pipe going into each entrie it should be ok?
we cant answer that tbh.
you would need a degree in fluid dynamics to work out the pulse length applicable to your engine if you want to retain your torque curve
