Hey guys, ive had a big problem with the interior resonance in my car. After chopping out the resonator, i got a lot of drone from the glasspack. So i bought a longer one, different brand---even more drone. Would a 4 inch diamater glasspack be noticeably quiter than a 3 1/2? How much quieter is the dynomax thrush models than the cherry bomb models? Does anyone have any suggestions for what I can do?

Before the resonator was chopped out, i was ok on highway commutes, but i didnt like the exterior sound from the resonator---can anyone help?

 

go with what you had if thats what you liked, or try to get another gm one...

or have a universal one put on...all exhaust shops have universal ones...just tell them you want to quiet down the inside of the car..they will know what you want
