anyone using the 4" single or dual cat back flo pro? I just wanted to know how loud they are and if there is any drone.

i got the single 4in and i like it. it was a good value and it was a good fit. i personally like it loud more sothan quieter. at first i didnt like it but i think it sorda got louder the longer its been on there, it sounds good though. look on videos in smoke shows and i havea video clip of the exhaust

I have a 4" cat back, quiet no drone. If you are looking for loud try MBRP with no cat.

rknrollo,

Basically if you leave the cat in none of the system brands are going to be loud or drone. When you pull the cat you will get louder and the potential for drone does exist.

I have the 4" aluminum (no kitty on my 2003)...bit louder but not offensive. Most of the time I have music on so I can't hear it anyways.
