Hello all,

I have a 06 GT with side exhaust and long tube headers. It is extremely loud. I originally had Magnaflow mufflers and now have Dynomax ultra flows, yet is still to loud. Can anyone recommend a high flow round muffler that is quiet? I can only fit round mufflers due to the side exhaust setup. Please help?

Thanks

 

have you tried flowmaster they are good give you growl but not to loud and i believe they are round.
