F82 BMW M4 Active Autowerkes mid-pipe before and after DB readings and impressions.
At Muffler Tech we not only specialize in catalytic converter replacement and protection, but also high performance exhaust upgrades.
In this video I do a before and after review of the Active Autowerkes equal length mid-pipe.

Sounds amazing!!!
Many people like the single, however, I really prefer the equal length and the higher pitched tone.
Did this retain the primary cats? Thank you

Yes.
Hey dumb question but I'm assuming an aftermarket mid-pipe like Autowerkes ISN'T CARB compliant (aka California's emissions laws). Do mid pipes involve deleting the OEM Cat convert? Sorry if these are silly questions, seems to be conflicting info out there in interwebs

When a smog is done in California the original mid pipe needs to be swapped back in.
Is this resonated or non-resonated? Also what type of exhaust? Full stock not competition exhaust?

@@mufflertech is it really raspy? I can’t get the catless downpipe because I have a convertible and the smell would be too much to handle. So I wanted the midpipe to give me that extra volume. I was thinking resonated but without the downpipe I might just do non resonated like you. Is the rasp annoying to you at all?

@@ZeusyZeus i don think it is at all. The resonated piece won’t make a very big sound difference.

Zero. He is an adult about how he drives it. The car is a pussycat when not in "M" mode.
