I'm looking into getting a catted downpipe for my M240i. Either MST or Active Atowerke. Does one have an advantage over the other?

Active is pretty awesome great customer support and us based. Believe mst is in Taiwan.

AA all the way. Proven no cel down pipe and if you do get a cel it’s easy to get it replaced by them.

Also them being a US based company is huge when it comes to support.

They have been in the bmw game for a very long time.

We offer both but Active is the top 1 option, in my opinion.

Its vastly more proven than MST, they also have excellent support.

So I get the general consensus is Active Autowerk is the go to for DP. They ever go on sale? $1500ish is a lot considering Mode has one currently under $600 also stating no cel warranty. Anyone try the mode?

if you dont want to deal with the check engine light and your car is not flash tuned, the Active Autowerke downpipe is the go to DP

Just bit the bullet and bought the AA catted dp + the Jb4 475hp kit. I don’t plan on flashing until warranty is close to expiring so I hope there won’t be a persistent CEL and it survives at least 30k miles of spirited driving with Jb4.

Thanks x-hp for having these goodies in stock!
