exhaust

[rockyw123]

I just bought a KN cold air intake and an SCT programer for an 07 EL.
I want to get a TB and exhaust to go with it.
Any thoughts on what cat back I should go with.
I also found some long tube headers with a Y-pipe for an F-150 by Pace.
Will F-150 stuff work on Expeditions?
I'm looking for the best bang for the buck and I don't want it obnoxiously loud.

Thanks for all the help and feed back.

personal preference...magnaflow, flowmaster, spintech, and others i dont remember...most say the TB upgrade is pointless...i thought about doing that but they say there are no gains even though the companies say it is..

headers wont fit... and a TB is so minimal gains for the cost it wouldn't be worth it until you start doing crazy motor mods.... and for exhaust it would be personal preference... I prefer flowmaster but search youtube for ideas

Magnaflow has sound clips on there site.

I know this may sound crazy to some but I didn't want to deal with the IRS so I just welded in an aero chamber straight threw muffler and it sounds great on the expedition. Which is a welcome change because I heard the same mufflers on a 4.6 mustang with stock manifolds and an off road x pipe and they sounded terrible

I have Flowmaster on mine too. I love it and even my mom (who is a grandmother so I won't mention age) likes it and rides in my truck. (I think she has been driving it while I have been gone here in the desert) LOL

How hard is it to remove the OE cat back system without a lift?
I was thinking of doing the removal and install myself but do not trust lifting the rear (eliminating parking brake) and do not have a hydraulic lift.
Can the exhaust be removed with all four tires on the ground?
