Exhaust clarification

Havy · 03-30-2019, 04:28 AM

Guys I am running nuts

can somebody enlighten me concerning the different exhausts for the M6 GC. As far as I know the following Nr. existing:
OEM non competition 18307845472-473
OEM with competition 18307849760-761
OEM performance 18302351490

Now somebody is selling a competition exhaust with the following Nr. 18307848441 but I cannot find that Nr.

is it really a competition exhaust?

and is there a big difference in sound compare to the non competition? I need more growl.

Not really the answer you’re looking for but if you want your car to sound better you might as well buy an aftermarket exhaust. My Meisterschaft GTC sounds incredible, way better than any BMW exhaust comp or not.

The part number -41 is just the tips. Here's more information:

Also note that you must buy a GC version. Otherwise you may have to modify all other versions (M5, F12/13). You need to confirm what car this part came from.

On the sound question, yes, there is a difference. Competition exhaust has a deeper growl. The value of this sound depends on how much you pay for this. I don't think it's worth $2k or above.

Thank you, but I have to respect our road laws. I need a Muffler with so called TUV.

Isn't Eisenmann TUV approved?

I found this BMW OEM exhaust parts list on the internet. It’s pretty much self explanatory. I hope that it will help you to identify the specific parts.

Look for used on eBay. M5/M6 rear section are interchangeable.

I may have a set of competition exhaust mufflers for sale in the very near future. You can let me know if you may be interested. Thanks.

Hi SoCalM6GC,
Yeah, I am looking but you know there are only 6700 GC out there and probably more than half are in the US.

Than, the ones with CP. There are not so many here in the EU.

Please keep me posted. As long there is a BMW # on it I can import them.

Will do. It’s all BMW OEM parts. They were removed from a BMW M6 and the mufflers all have BMW parts code listed on them.
