I've lifted the RB systems and the are kind of hefty. I can lift my entire exhaust system with one hand. Its a Corksport Catback,RB presilencer, RB DP with Resonator. But even a RB muffler is pretty heavy. I think Its as heavy as my whole system.

But I say stick with your current set up. and get the 2-1 header with a Xr-1 borla or resonator in between to quiet it down. I don't think shelling out the money for the true dual is worth it. IMO

 

what about power numbers between the two can i make as much with the 2 to 1 header and other parts as i can with the true duals?
