What size baffles are you using in your mufflers?
I'm running V&H 'True Duals' with Samson Mufflers (with 1.75 baffles). I didn't notice any appreciable loss in torque.
Sound is a nice rumble but mellow also.

True duals work good on big inch builds. Lots of guys like them for the looks and sound but you will not get the low end torque that you will get with a good 2 into one exhaust. Your decision, looks or performance.

thank you for your anwser.
bike was dynoed by the mechanic manager of a hd dealer in spain. unfortunatly we dont have many dyno tunning machines in Spain (just 2 and none of them wants to work with sert, only power comander).
this afternoon I changed the kerker muflers and put the oem mufflers to see what happends, I went for a ride and the low rpm torque came back, the throttle response is no good with the 1-1 ratio so I will change it in order to have a progressive throttle.
after uninstallig kerker mufflers I saw that the muffler is "hollow", I mean, it has a baffle inside with quiet mat but theres no retention, it is just a straig pipe and you can see the light if you see thru it, so gasses run free with no retention or backpreassure all the way out tru the pipe. if theres no retention theres no torque.
I went to the dealer and saw a couple os SE street leagl muffler, you cant se tru them so there should be some kind of retention, maybe they'll do the trick.
BTW anybody with a 2009 bike with true duals and a right map would mind to share it?
thank you
