I have a 2001 GT with an automatic. It has an H-pipe with flowmaster mufllers (not sure which flowmaster mufflers) there are no resinators on the car. The car sounds good but when driving at certian rpm's it can be very irritating inside the car. What options can I choose to help this problem? Different mufflers maybe, if so what kind?

A straight through muffler will solve the problem. Any chambered muffler will drone like the flows.

 

+1but shifting can eliminate the drone

 

oops my bad...didnt notice that you had an auto.

 

Ahhh the 2000 rpm Flowmaster drone....it's part of the Flowmaster experience! I like it though, I purposely got the 40 series for the most drone possible!
