I have a 06 f150 with a cb extreme and have been thinkning about the magnaflow 94106. Just wondering if i should leave it or get the high flows?

 

I have hiflows on mine and I have no regrets. Pn# 94036. Ok one minor regret. Next time I would get one without the O2 bung in it. The OEM O2 wiring harness is too short on the pass side so unless you get an extention for it you'll have to cut back part of the pass side heat shield like I had too.

 

What kinda sound differnece was there??? hollow sounding???

 

Not hollow sounding, at least I don't think so. But you will notice they are there. Combined with my catback the truck has a nice rumble at idle or when cruising.
