Hello, I currently have a m2 performance axle back exhaust with a resonator delete and im looking for a little less drone between 1.5k- 3.5k rpms. I was thinking I would get somthing like a magana flow resonator but it seems that no one has ever done that before. Are there any good resonators out there? Also I was thinking on top of getting a new resonator deleting some of my cats.

 

I think you should put back on the stock resonator. It will quiet it down.

 

I did the same thing on my is350 2007.i also wants less drone.i bought some after market resonator but still there a lot drone.my friend gave me ISF resonator. i will install it next week hopefully less drone.but what you think about ISF resonator sound in is350 m2 exhaust

 

Go to your local muffler shop they should have a magnaflow resonator. The magnaflow resonator quiets it down but keeps it just a bit louder than the stock resonator. That's what I did with my car. I also have the M2 exhaust system and it sounds great with the magnaflow resonator. My friends are always telling me it sounds great.
