MPE + DP Owners
Hey guys,
This is kinda directed at people with Catless downpipes and an MPE exhaust. I just installed my ER Catless DP last week. It sounds amazing, but there's some rasp at around 3.5-4.5k RPM. Anyone else has this? I might uninstall the DP if I can't resolve that rasp because it sounds like a mix of a Nissan 350z and the M4 and I hate that. Any suggestions would be appreciated.

HJS 200 CEL Cat, and was confirmed by the dealer located Toronto, Canada that there will be no issue with keeping warranty. Factory Cat is 400 CEL. I dont know why your dealer is okay with 300 CEL, not 200 CEL?? |

But i’m happy with the sound. With valves open it’s very loud. Valves closed it’s sporty and no drone. Throttle response improved also. Friend of mine, with MPE and 200 cell Wagner do have drone.

I have ASD still on did not kill it by coding. So does drone at certain speed and certain RPM. No difference for me to feel between having DP or not much
