I think would be a great set up would cut the muffler and add two more factor resonator one each side before of your quad tip. The sound would be deep and no drone an lightweight. I would try this if i had a m2.

Here is how it looks after:



We sealed every up, and the result in the was bit more volume, and huge amount of explosions in sport/sport+ and traction mode.

When I say huge amount, I seriously mean that those bangs explosions doesn't want to stop....

From the inside, we have perfectly retained the comfort mode were you can't notice any difference or drone, while in sport+, there is indeed more volume with already added 200cell downpipe.

Unfortunately, it's raining today so there was no possibility to make fly by video, but I made one in traction mode and other in sport+ while still in the garage.

The engine was cold, and this is how it sounded just up to 4-5k.

Traction mode.

Sport+ (cold engine)

Overall, I regret why I didn't do this two years ago, and waited to grow some balls first, before I decided to pull the trigger on 80 bucks mode...
Did you had wool inside the muffler and if so, where? 🙏

Yes, there was was some, but we added more just in case some little shard from drilling won't cause some excessive noise.

This muffler design just looks crazy to me, all the bit here and there, the chambers, the bends, the bulbs on the back of where the pipe comes out of the muffler box. I guess it's all done for creation of a specific sound, a tuning of sorts. Weird...and HEAVY.

What % increase in volume do you think this had? Interested in getting this done myself combined with a resonator delete but I cant find any info on the increase in volume from this mod alone.

Thanks

Lets say that it's around 10 to 15%, but please be aware that with in combination with de-cat downpipe (200cell) you will have a lot of drone in comfort mode in a highway.

I've returned back to stock right now, and in the future I might simply create a simple Y pipe which I will replace when going on track.
