I really prefer the look of quad exhaust pipes a la M3/M4. Did anyone do this conversion on an M40?

I did for a while, remus exhaust, but it sounded bad, so i switched back to the stock end muffler.

I'm surprised by this, bad in what way? Too loud? Drone? Too many pops and bangs?

Appreciate the feedback as it's the first mod I'd consider.

only "loud" at 2000rpm and a lot of drone at cruising speeds.

Perfect post, thats the 1st mod i want to do is to replace the rectangular layout with actual rounded exhaust tips on the stock exhaust, who makes it?

I replaced the stock tips on all my BMWs

Yes, I have replaced my stock exhaust with an AC Shnitzer four pipe one. IMO it looks so much better than stock. It sounds nice on a cold start.
I'm still running in so I haven't heard it at it's best. I'm happy with my decision.

Do they sell only the tips? Can you share a pic? Which vendor?

Thanks

There might be an option to replace just the tips? Is there enough room from the main muffler canister to attach a new pipe that then bends and eventually terminates in a dual or quad rounded shape?

Probably easier said than done. Some shops are pretty good at fabricating but getting the raw materials might not be exactly easy.

I had my exhaust fitted at the same time as some lowering springs and performance upgrade. All ACS, they were fitted by ACS UK.
I'm not sure if the sell just the tips.
I have attached a couple of snaps, apologies I am parked quite close to my wall ):

Looks ok, but WOW, nearly $6k for a can and a few tips. That's more than 10% of the value of most used G29 M40s on the market today. Enjoy them in good health, but that's a "hell no" for me....

the bend of the exhaust pipe sits pretty close to the bumper, it might be hard to find a Y shaped tip that is short enough.
I don't know what is possible.

The AC/Remus tips require dual pipes from the muffler, so i don't think it's an option.

*edit* also the carbon tips are close to 1200 usd for remus, i imagine the AC Schnitzer ones will be the same.

Agree , i would not spend more than 2K for a rear section exhaust a, any other vendors. Checked IND they have Eisenmann rear muffler for 4K

And it's stainless steel, not even titanium.

I miss the days of $3000 titanium exhausts on Japanese cars.

Does this fit?

Interesting, I love the look of the stock exhaust on the M40i.

Joe Achilles did a good review of the AC Schnitzer option

[boss2k]

Found another option and called them and they cannot guarantee fitment, asked me to measure the inlet and OD on the car

[BEAR-AvHistory-2]

Hope someday someone finds ones that will fit. Would make the swap in a heartbeat.

Unlike the rest of the G-series OEM back boxes, the G29 exhaust tips are welded onto the tailpipes, which exit the muffler at an approximate 45 degree angle.

Something like these tips could probably to work by cutting off the stock outlet pipes from the muffler, recycling the old valve, and welding the new ones on centered within the rear diffuser outlets.
