Hey, I want to get a RB header and maybe a presilencer. I have straight pipe right now. It is from the header to a high flow cat then to a new y-pipe and no mufflers. Since I am going to have to reposition some things anyways should I go ahead and get my presilencer at the same time? Is this going to be to loud since I do not have any mufflers? How much power do you get out of this?

 

yeah i already PM'd you its going to be loud, the power difference is good i don't know how since i haven't been to the dyno
