So I originally ordered my F150 through the AAFES Exchange out here in Iraq. The first order was based on 2010 specs, but i got my email with my final build sheet for my 2011 F150 super crew. I ordered it as a 2wd crew cab with a 6.5 ft bed, 5.0, 3.55:1 rear gears with limited slip,tow package, XLT Convenience Package, and XLT Plus Package, and 5" round Chrome Side Steps (for the wife). Set for delivery in February 2011 to hawaii where i am stationed. Plans include a y pipe back 3" exhaust, Snug Top XL Bed Cover, Bed Rug, and window tint, and possible 5.0 badges. It will be sterling metallic grey.

 

After owning several of F150 and Expeditions over the years, if you're gonna do exhaust work, get rid of the 'y' pipe. It adds so much more throttle response. I know the newer 'y' pipes are designed better, but you're still combining 8 cylinders into one collector. The way you plan on doing it will cause more noise (good thing) but you will actually lose power, not gain it

 

what do you mean get rid of the y? u mean run something like the flowmaster collectors that go 2 into 1?

 

I think he means true duals with an "X" pipe.

However - we have yet to see what the stock 2011 exhaust looks like.

 

will a y pipe back be worth any gain? exhaust sysems in hawaii are expensive as all hell. i PAID $1100 For true duals on my 1993 F250 and they didnt even mandrel bend the tubing.
