Wideband A/F with true duals
#41
Hammer, over in the 3rd gen FAQ has a chart on flows from various mufflers.. If you haven't purchased yet, you may want to give that a read.. In short though: FM's have NOT mastered flow- they flow only slightly better than OE.. They sound real good though as they use a chambered approach.. MagnaFlow and Borla use mostly baffled approaches, which 'whoosh' as opposed to 'rumble'.. they don't sound as good, but they breathe FAR better by NOT producing back pressure.
I have a magna true x dual in dual out muffler.. I swear, you can drop a golf ball THROUGH it w/o touching the sides it is so open.. Again, it whooshes more than rumbles, but it flat out breathes.. I have a pair of magna-flow high flow's no more than 18" in front of the muffler, so I get pretty decent scavenging I'm thinking..
If you are still planning, and haven't bought anything yet- it would do you a lot of justice to break out the calculator and measure/fit every aspect of that exhaust before-hand, and while taking into consideration future mod's. Just my thoughts on the matter.
good luck dude!
