GLC43 Coupe Stock Exhaust Size?

Anybody know the stock exhaust pipe sizes of a non performance exhaust GLC43 Coupe?

I am considering an aftermarket exhaust system and the seller replied to me that his pipe sizes are

[The size of the pipe is 2.75 x2 and then 3 inch and then 2.75 till mufflers.

Thanks,

We have the dyno chart in hand. It increases for 10 HP.]

Anybody wanna share any thoughts?

When I removed the resonator for a y-pipe, the downpipes were 2.5 along with the piping to the resonator. After the resonator the pipes go up to 3 inches to the rear muffler. My Y-pipe is 2.5 in, to 3inch out.

The exhaust you mention from that guy will be a little bit larger than stock; however, why did he drop back down to 2.75 at the muffler when stock piping to the muffler is 3inch?

I am having something custom made. It will be very similar to FI Exhaust's setup. dual Mid Pipes 60-63mm diameter into a electronically controlled valved muffler. It will be controlled by remote. I decided not to use the OBDII port to control the valves and I also decided to keep the stock dwnps.

It should be ready to install next week once it finishes fabrication.

Post videos once installed if you wouldn't mind. Curious to see where the valved muffler is sourced from. Im tempted to take the muffler off and put straight pipes out the back but don't feel like having a pounding headache every time i drive and the times I don't want to be that a-hole with a loud *** exhaust.
