ER Downpipe noise.....HELP!!

BPe90M3 · 03-25-2015, 09:34 PM

I installed my ER downpipes back in December. Loving the intoxicating sounds and great throttle response, even though i have no tune. One thing I have noticed is that in the lower RPMs (I wanna say between 1k-2k), I sometimes hear a rattle type sound. It sounds like waste gate rattle to me, but I'm not sure if this is normal. I know this was a common issue on the N54/55, but wasn't sure if this is something to be expected on the F8x, or if i need to bring it back to the installer and demand they fix it. Any insight is appreciated!!

Shouldn't have any rattle at all. Contact your installer and give them a chance to correct it for you.

Doubt it, likely just needs to be adjusted a bit.
