hey guys i have a 2004 JB RCSB supercharged. what is the best exhaust to go with for the best performance results??? right now i have long tube headers with 2.5" exhaust straight pipes. the truck run great with straights but sounds like crap. i just put 2 magniflow 2.5 in/out 6" dia mufflers on it and seems like i lost power. they are true duals with no x pipe or h pipe. am i missing something? i need opinions on the best size and rout to go with exhaust.

thanks!

I lost power in the low end with true duels but always picked some up on top . I would maybe try adding a xpipe or H depending on the sound you like . It might add enough restriction to get what you lost but nothing flows like straight pipe so im sure you lost some power there .
