ISO Muffler section delete
Morning everyone. I own a 2018 CLA45 currently stage 2 Eurocharged with weistec intake, akra catless DP and both resonators deleted off stock midpipe(non-AMG exhaust). So I’m sure the stock muffler is restricting me quite a bit. I’ve been playing with the idea of trying to get a straight Y pipe to replace the muffler to see a power/sound difference. Of course flames are always fun too. I would like the Y pipe to have a flange of course so I can swap muffler/straight pipes if needed. I’m located in NJ, USA. If anyone has any info or recommendations let me know!👍🏻

Actually, the only difference between the AMG "performance" exhaust and the non-performance exhaust are the resonators! The non performance exhaust came with 2 big resonators, while the performance exhaust came with one smaller resonator close to the muffler.
Unless you want LOUD all the time, I would leave the stock muffler on. When you go in sport mode, it opens up the valve and is practically a straight pipe anyway. At least now you have the option to put it back in comfort and quiet it back down. You don't gain much hp from removing the stock exhaust, maybe 6hp if that.

My muffler does not have an active valve, I went looking around down there a few times just cleaning and what not.
And as for the restriction, I’d say in any case the muffler is certainly more restrictive than any resonator. As the resonators as simply straight through piping surrounded by baffling. Either way I’ve deleted both resonators. Leaving just the exhaust being the last restrictive piece. Being catless and tuned, removing that restriction would certainly yield a notable gain. Mainly looking for the delete section to get the most out of a dyno session.

This is the route I am going myself next Monday. If it is stupid loud, I will just add a small resonator back on. Catless and with the resonators off it seems quiet for my taste. I have been looking for a Ypipe but couldn't find anything myself. Keep us posted if you do though!
