Open headers vrs. full exhaust

Are you dropping the exhaust at the track??...you'd deffinately see a gain if jetted correctly..but he's talking about through the dumps...

I don't drop all the exhaust, I just pull the mufflers. That leaves headers to merge collectors into an x-pipe and a little bit of pipe leaving the x-pipe.

I still think through the dumps there something to be gained if its jetted correctly...Like anything take it to the track and have some fun
