Just got my new exhaust installed. Its a custom 2.5in catback with 2 Vibrant bottle style resonators and 2 GReddy revolution RS mufflers. I absolutely love the sound. Problem is, there is a significant amount of drone in the 1800-2500 rpm range. What do you recommend to fix this? The muffler shop advised me that more resonators could be easily added if I wanted them. I was thinking of adding Vibrant ultra quiet resonators in addition to the ones currently on the car. Any suggestions are appreciated. Thanks!

 

you got it...add more resonators....the one you are thinking about the vibrant is a good one...go for it.
