Question about PE mod and drone

TheGoodTheBadTheUgly · 07-19-2021, 08:57 PM

[QUOTE=BavarianMotorWorks;27821685] I have very sensible ears and noises like these rewlly get on my nerve. I can assure you that my setup has abolutly no drone. Yes the in cabin noise of the is louder (not annoying at all especially when cruising to mid-high rpm), its inevitable but there is no drone or raspiness it's a very high quality sound.

The performqnce exhaust from BMW comes exactky like the mod you are doing. I remember in a post someone sacrificed his PE exhaust and choped it open, it was exactly the same concept and setup.

Yes with MHD the flap remains open except on cold start. I thought stock it would act like this as well but it's been so long so I can't say.

Okay good to know that you're pretty sensitive to drone as well.

I don't mind more volume of the exhaust note like you describe. It's just the bassy resonance and drone that would bother me.

I think you have me convinced to stop by my local exhaust shop.
