OEM exhaust mod with 2nd cat delete?

raywong · 05-27-2012, 01:49 PM

I am going to try the OEM mod, wondering how it would affect the sound if I delete the secondary cats too. has anyone tried?

I did the oem exhaust mod with a primary cat delete...

TRUST ME...the car sounds INSANE.

I dont think anyone has done the combo you're looking for. I guess its worth a try??

But it definetly won't sound like a primary cat delete.

This M3 is my family car so I don't want it to be crazy loud.

Trust me, I heard GreeKon's monster yesterday. My son heard it and thought thunderstorms were approaching. It sounds amazing. It will piss off your neighbors though... alot.

By insane do you mean raspy?

I have heard people saying deleting the secondary cats does little to no difference at all.

I have the OEM exhaust mod and I am about to delete my primary cats.. Or maybe go with HFC's to avoid problems with inspection
