That's my philosophy. The startup is so sexy, revving at a red light is so damn fun too!

FYI if you have drone issues with the AA exhaust, I plugged the other 2 exhaust mounts with synthetic wine corks like I did to the other one and wow basically all the drone is gone now. Driving at 2k rpms on the highway is annoying some times but now the 2k rpm range is smooooooth and drone free. (maybe 10% of quiet drone left)

Sounds similar to mine now! Just got the AA exhaust, resonator delete done and it sounds pretty aggressive. A bit of drone between 2000 to 2500 rpm but that's about it!

Tried this. The hangers are shaped like diamonds, but I tried stuffing 1 cork in each hanger to no avail. Drone still present and annoying, my AA is coming off for a used PE.

12,000 miles later with the AA exhaust

Sorry. The video was meant to be longer...Camera battery shutoff and I didnt feel like doing this tomorrow.

This thing got so much sweeter sounding, especially upper RPMs!

Installed last february so roughly 12,000 miles later. Hope you like it.

High quality recording of 325i MT Muffler delete

I didnt see any high quality footage of this so I decided to do it on a hunch. Very pleased with the sound and noise levels. No highway drone when at 2600-3200 rpm (65-85mph)
The only droney part of the rev range is about 2100-2350rpm That is where the most "drone" occurs. Im not bothered by it because Im usually below 2000rpm or far above it. I had this performed at a local exhaust shop, they welded a flange in place so the muffler could be swapped in a matter of minutes with basic tools, and it uses the stock muffler hanger. Cost was about $120 after tax.

My Active Autowerke on my E90 330i before I swapped it for a PE muffler and had a shop delete the resonator. Loved the sound, but that infernal drone from 2k-2.4k was too annoying. And everyone that rode in my car knew it...



i'll make a vid with the PE later. It's too quiet for me, so I may remove the secondary cats in the future.
