Does anyone out here have a factory JCW muffler that they have replaced with an aftermarket system? I'm wanting it for my 2007 r56 MCS... If anyone has one, let me know your location and price!

 

If I could hijack for one question. I want to make our 13 MCS a BIT louder, but with no drone and no decel pops and bangs.

Is the JCW muffler a good option? I would keep everything intact except of stock muffler...

TIA,

Popping and burble have nothing to do with the muffler. It's in the ECU programming.

Akropovic. But it will cost you about $1800 It's the best aftermarket catback.

Yes the factory JCW muffler is a nice upgrade. It does not drone at all.

 

Thanks
