Downpipe yes or no

Bimmerboy017 · 08-09-2021, 10:20 PM

bmw m240i b58 with m performace exhaust. Will it make a good loud sound?

Adding a downpipe on the B58 will make things noticeably louder for sure.

Apparently can spit flames too with a tune!

Clickbait much ⁉️

High flow cat > catless but if you want the sound I can't blame you.

Get the active autowerke catted downpipe. It sounds great and does not throw a check engine light

I personally prefer the sound of catted over catless, its got a deeper mid-range tone and no raspiness on high RPM

My dream set up would be catless with a AWE catback. Since I have to smog every year I can't do catless. A catted downpipe is last on my list of things to modify if I still have the extra money.

Ajowhan · 08-11-2021, 07:38 AM

Yes, go with AA high flow catted downpipe like Mike suggested. Definitely a welcomed improvement in sound.

jordan24c · 08-12-2021, 12:36 PM

Corroborating Mike and Ajo - AA Catted is the absolute move. Sounds amazing with a catback.

WolfGTI · 08-12-2021, 12:48 PM

Agreed AA catted is a great way to go.
