Aftermarket Exhaust

[bikeme2001]

I just got my 2001 2500 hd with the 8100 motor.I want some sound out of it and bought the dynomax ultra flo ss from summit racing.I always seem to ask ?? after I buy something.Anyways has anyone got 1 and if so how do you like it.I want to put the exhaust on first then a cai.

I have talked to Jesse at wait4me and Im thinking after the cai ill do the tuner thing.

Have installed only one and the guys likes it I like the flowmaster myself I put two super 44"s on my 05 2500hd 6.0 just to get the factory choke box off and picked up about 1.5 mpg with just the mufflers.not too bad on sound I love the flowmaster sound anyways In any case you will like the mpg pickup
