Hi Guys
I own a bmw f30 328i,and I install the supersprint exhaust system on my car.I have felt a little loss between 1000-1500rpm.and I assume welding the oem valve on my SS exhaust endpipe,can it be okay?

Great Idea! I cannot think of a reason why it shouldn't work. But have you also installed the downpipe? Probably that's the real culprit.

BTW, notice any drone?

don't see why not. I know Akra and other companies reuse it.

No,I have not installed aftermarket downpipe.
With Supersprint exhaust system, there is almost no drone,but a little bit around 1500rpm,but I have got used to if after running half a year

Supersprint has release new product for f30 328i with valve.that is the reason why I think we can weld the oem valve on the ss exhaust endpipe.
