ok... here's what i have done. i had stock manifolds, into cajun b pipes with no cats, into y pipe, into Cherry Bomb Extreme SI / DU exiting rear bumper. BAD BAD BAD CIS. so i swapped mufflers yesterday. now i have a DUAL IN DUAL OUT Borla Pro XS. CIS is completely gone... i mean COMPLETELY. That being said, it's only about 50% as loud as it was before. muffler is part number 400286. sounds good behind the truck. absolutely no drone inside... actually, you can hardly hear it inside if the windows are up. if you step on it, you know its there though. i'm satisfied for now. will be putting headers on later to wake her back up.

Howdy night owl. I have an 08 Pro-4X. I want to get stillen headers and your Cajun b pipes with high flow cats. Will this pass emissions in Georgia, since the stillen headers would delete the factory front cats that are attached to the exhaust manifolds? If it won't pass emissions, what other options do I have?

I would appreciate anyone's input.
I can't guarantee anything on the emissions thing but I can tell you the berks and stillens pass and my bpipes are just as good if not better while being a lot cheaper. I have only sold a few sets of the cat pipes and no one has complained about emissions or cel. The cats I use are 400 cell highflow cats with a 5year/50k manufacture warranty. They are nice!
Sounds good. sure can tell a difference, How do you like it?
I like it so far, seems like most of the CIS/rasp is gone during parked revs and take offs from a stop. Haven't had a chance to cruise the speeds & rpms where drone is at it's most potent.
Hi y'all. I have an 08 pro-4x with stock exhaust. I added an 18" magnaflow dual in/single out muffler. I'm getting a lot of CIS, especially when the truck first runs until it gets warmed up. I bought a Borla pro xs but the guy at the muffler shop talked me out of the borla and I put on the magnaflow.
I'm thinking about switching to the borla. Should that get rid of the CIS sound? Any other suggestions?
22" Magnflow (2) 2 1/2" in and (2) 2 1/2" out
Dual 2 1/2" pipes out the passenger side (stock location)
Installed yesterday!
Loudness - maybe a 7 out of 10
Drone - very little...need to drive it more to properly access
CIS - none
Rasp - none
