I had a Gibson Swept Side installed on my truck eight to ten months ago. I do like and have had no problems with the exhaust, but I would like it to be slightly louder. Instead of buying a whole new system I would like to replace the gibson muffler with a new one that is slightly louder. Any idea which muffler this would be? Any suggestions would be appreciated.

 

one thing about the Gibson Swept side that i particularly like is that there is zero interior resonance. i am sure u are very acustomed to that and i love it because it makes driving easy when i have a headache and dont wanna hear my exhaust.

but that said louder does sound cool and turns heads.

if you want to get more noise, but still maintain low levels of resonance i would say go for a flowmaster 50 series delta flow.

i have a dynomax super flow muffler on my chevy truck right now and it only has a smooth, tolerable resonance.

 

Sounds & performs awesome!
