So I'm thinking of removing the stock tips from my 35i by grinding off the small weld holding on the OEM tips
Having measured the OEM piping ( not the tip ) bizarrely it appears to be 70mm inlet one side and 73mm inlet the other side
I'm thinking of trying the BMS tips for the 335i
Has anyone managed to find some slip on tips which clamp onto the OEM tubing without cutting ?
