Hey all,

I just moved from my JB4 to the BM3. I'm driving a 2017 230i, along with purchasing the tune today I also installed my catless DP. Now with the catless dp, every time I turn right/left (AND when the motor is under load in a turn, i.e., giving gas) there seems to be a noticeable rattle coming from the transmission/downpipe area (mostly felt on the floor around the centre-right area of the car). I want to know if this is normal? Did the exhaust shop install the DP loose? Is it a fitment issue? is there a leak? Unfortunately, I do not have any logs, but I wanted to get your opinions? I'm calling the shop first thing to get it evaluated. In the meantime, has this ever happened to you?

Thanks,

SJ
