Have you done this cutout to e39 m5 oem diffuser?

Hello,

Looking to upgrade to Supersprint oval muffler, which requires about 9" width.

Putting the stock OEM diffuser next to the muffer, picture below.



Seems like the OEM diffuser is a (soft) plastic.

Anyone has done cutout to the stock diffuser, and used what tool? Dremmel? And undercut, sand the rest?


Thanks much.

Shaving with a dremmel like tool is probably a better route.

That doesnt look like a Superprint exhaust, at least not an M5 exhaust. SS offered 3 muffler style for the E39 M5, and none required cutting into a painted panel/trim.

Personally on a delicate cut that can't have mistakes I would stay miles away from power tools. I would tape up both sides with two layers of tape and draw my lines. I would clamp it in a vise or down to a bench. I would get a fine blade for my coping saw and install the blade so that it is pushing thru the painted side depending how I clamped the part and which side I was working from. I would move my clamping likely a few times because the small side looks like it will move if not clamped close to it. I would likely switch sides also which would mean I would turn the blade around so that I was always pushing into the paint.

It's non-e39 m5 replica exhaust with oval tips,

Okay, thanks.

This shop has done similar cutting before, their cutting pictures below.

Seems to me like a really clean cutting.
