Anyone running this setup? Really want to get some more power with catless headers/tune but don't want to go super loud. I had a Gruppe M on my old M3 and want to be quieter. Basically looking for some insight on the sound/rasp. Thanks!
I have that exact setup. It***8217;s definitely not load, sounds way better with the ar25. I think the 25 is the one to use. It was embarrassing before adding the ar25.
Not really any rasp like without the resonator. It's kind of a tiny sound like a gt3. I really like it.
