245/300
On the plus side = Xcal2
On the minus side = Slowmasters & a dirty center console
Lose the Bafflemania plumbing & you'll see better results.
BTW - Didja do your maintenance? Fresh fuel filter , O2's, etc?
Have fun & good luck!
Cheers

MGDfan: The Flows may be slow, but mmmmm they sound good!!! https://www.f150online.com/forums/sh...d.php?t=252292
My truck has only ~12,000 miles on it so I haven't done any service other than oil changes yet. I suppose some of the hardware is coming due for cleaning/replacement but I figured everything should be 'good enough' for now.

FYI.............................................
From the Flowmaster Faq:
http://www.flowmastermufflers.com/faq.html
Will my late model vehicle run better if I replace the single inlet muffler with a true dual exhaust system?
Flowmaster does not recommend replacing factory single inlet exhaust systems with a "true dual" system on computer controlled vehicles. The computers in most late model vehicles will not be able to compensate with the fuel needed with an almost doubling of the exhaust flow. Flowmasters dual outlet kits will give you the look of a "true dual" system, while optimizing the vehicles performance.
How much will it hurt the hp/tq?

I got my coasters down in Myrtle Beach this summer while on a little vacation. Have you seen the NC State Edition F-150's rolling around yet? That dealership down 401 South had 2 of em, a red one and a black one. Both looked real nice but a bit too much $$$... They also had a WF and UNC one, but, eh
Silverfish: Hmmm "The computers in most late model vehicles will not be able to compensate with the fuel needed with an almost doubling of the exhaust flow." That part there sounds like they're saying if you put true duals on, you run the risk of leaning out the motor. That doesn't really make sense to me. Since nothing is being changed prior to combustion, I don't see how allowing the spent gasses to exit the engine easier has any effect on fuel required. I'm by no means an expert so maybe someone else could chime in here....

Hi.
No worries NCSU, it's BS.
The main concern with Flows and another sub-optimally designed exhausts ( crimp bends, tubing too large/too small, lotsa baffles, etc, etc) is it's effect on exhaust gas velocity and it's negative impact on effective cylinder scavenging. Think 'velocity' NOT 'backpressure'. This is of primary importance to preserving torque levels.
Search will turn up a ton of details on this. Been there, done that.
Flowmaster has never, and will never be, the definitive source of performance-oriented products OR advice.. Sounds real good on 'stangs though 
Waiting for your numbers! What do I win?
Cheers
Bubba
