Aero Turbine (AR25) Resonator?
 

Has anyone ever installed one of these in place of their stock resonator? Currently I have a muffler delete and while I like the sound I get from that I would like it to be a bit deeper. It is a straight through design resonator designed to cut out rasp...a lot of e46 m3 guys run this to eliminate the nasty rasp they get but I dont think it cuts down the sound too much. But I have been searching and I havent really seen anyone running one on a speed. I was hoping that installing this in place of the stock resonator would bring out a bit more sound. Ive thought of going straight pipe but dont want any rasp...thought this might be a good alternative...

Thoughts?


Performance Exhaust Resonator

So if I understand correctly, you have a stock catback with the big muffler in the rear section near the tips replaced with just pipe, and the resanator towards the middle of the car left in place. I'm pretty sure replacing that stock resonator with this will make it sound "better," but I'm not exactly familiar with the characteristics of that stock resonator vs. this. For reference, your average high quality aftermarket muffler/canister from HkS or Greddy or something like that will make an obnoxiously loud straight pipe setup have a much nicer, more refined tone, while still being plenty loud.

Post a clip of what your exhaust sounds like know to give a better idea of what's up with it currently

I added a Dynomax 24222 resonator to my test pipe and it dropped a substantial amount of the gargling / rasp and even a good bit of highway drone. I can't imagine they are much different - the sound quality will likely be affected most by the packing around the perforations.
