Exhaust question...

I was looking at our exhausts when my mss sleeves were getting installed and saw there was one main muffler that split off to two smaller mufflers. With limited options out there would it be worth while to cut out the middle muffler ? Not sure if it’ll make a big difference or not but wanted to see if anyone thought about doing it or have done it.

Hi and which? Slip on or the middlepart also?

In akra said slip on = guarantee is as normal. Middlepart = you may lose guarantee

Do you have any information from bmw?

I recently talked with my Dealer and SA about exhaust as well. They told me as long as I don't remove the down pipe connected to the turbo they have had no issues with warranty. I'm just sitting waiting for other systems to start to come out to compare, find the right one for me.

The X-pipe if it really is one is just a resonator. I did this on my 50i and it had almost no audible difference.

Good read on resonators.
