Get straight-thru mufflers
Chambered mufflers drone like crazy
I had Flowmasters and put resonators on... it only cuts the drone down like 10%

I have a Bassani catted x-pipe. The cats there are high-flow cats. I used to have FRPP Stinger mufflers and there was plenty of drone. So I'm saying high flow cats are not going to stop your drone.

I had 3 ideas for solutions:

1) add a Pypes mid-muffler (in addition to the catted x and stingers)
2) replace Stingers with Corsa's
3) replace Stingers with GTA's

I eliminated option 1 because I was tired of experimentation.

I eliminated option 2 because after listening to many youtubes I felt Corsas sounded great on the outside but were too quiet on the inside. And what volume was on the inside lacked depth.

So I chose the GTA route to keep some throaty sound and eliminate the drone. I haven't installed them yet, BTW.


+1 for the Bassani catted X. As far a exhaust sound goes, I'd call it a half step towards adding headers. It turned up the volume and added a raw attitude to the exhaust note. Only down side (for some) is it is just a little raspy below 2500 rpm. The rasp was barely noticable with the Stingers and a lot more apparent with stock mufflers. I'm hoping the GTAs will add enough depth to cover that up like the stingers did.

I could believe that. I took my carpet out of the trunk temporarily and the resonance and noise in the cabin went up considerably.

Having resonators installed is probably the best long term solution. I was actually going to get the mac mufflers until I heard about the excessive drone.

one word to remember CORSA. had FRPP and suffered drone to the max, changed to Corsas and had none

I currently have a wadded up blanket in my trunk, it didn't really do much except keep my spare tire a little warmer. I think the drone is apparent with driving style. I have Macs and the only time i notice Drone is when my Dad is riding with me, He's almost 70, so I have to drive alittle more smoothly. Course, I have a 5spd so its easy to keep out of the drone zone of 1600 to 2000 rpms. I'd say get some resonators and have them put in. I think Summit might have some.

anybody else have any opinions?

Just do the corsas. They are your only sure bet of eliminating drone.
