Currently have a MBRP downpipe to MBRP 4" exhaust. I'd like to upgrade to 5" exhaust but I'm leaning towards a Flo-pro system. Just wondering if the MBRP downpipe will work with the Flo-pro system or if I'd have to change the downpipe aswell?

my understanding is unless you are running heavy mods the 5" exhaust is unnecessary.. Am I wrong with this perception?

The difference in 4" & 5" is the sound, power doesn't matter. Also, MBRP fitment < Diamond Eye & Flo-Pro.

Buy the exhaust, as stated the sound is the only difference.
