Y-pipe into N55 M performance muffler?

MrOhnoez · 03-01-2021, 01:18 AM

Little curious if anyone has attempted this.
I've come across a free N55 M2 performance Exhaust muffler,
I already have Catless VRSF catless Downpipes,
I don't plan on doing equal length as upon hearing everyone that went catless complained about the sound and tinnyness.
I plan on going from a catless DP into a resonated Y pipe, and in turn into the M performance muffler.
All of which on an S55 motor.
Curious if anyone out there has ever tried to slap on the M2 N55 performance exhaust on their M2C?
I think it'd be at least worth a trip to a muffler shop to fab something up.

Personally I have never heard of anyone doing this, but the muffler should fit and bolt straight up if you buy the N55 m2 hangers and exhaust brackets.

Then the rest would be up to the fabrication guy to make it work. However I do not know if the muffler would improve the S55 sound, you would be the pioneer on this front.

The N55 MP exhaust is a straight pipe with the valves open. It's loud.
As the valves normally open with revs on an M2C in all modes, I guess the issue could be control of the noise?
But then again if you paired it with a valve controller then problem solved.

I'm curious if I could get the valves to work with the factory system implemented on the M2C.
