I would definitely not say Big gun they are loud even with the quiet core. I would say either a Pro Circuit Type 496 S/A Silencer or the White Brothers E2 Silencer. I have the Pro Circuit on my 2004 440 EX and it has a little noise but i like the lower sounding noise instead of the loud pipes that constantly backfire. But for the Pro Circuit it has AMAZING horsepower gains for the noise level. I have the White Brothers E2 Silencer on my 2005 450R and it also has huge horsepower gains for its sound but horsepower isnt eveything so both exhaust are VERY LIGHTWEIGHT!!
