    Don't you have those obsolete 21" long Borla XL's? That's what I would have used if available, so instead I used 18" long Magnaflow XL chambered mufflers.
    You "feel" the difference because you want to "feel" the difference. Since you just spent money on the upgrade you "have" to feel the difference

    I'm looking to eliminate the double pump process I have to follow right now to get the pedal hard

    Yep. Too bad they quit making them. Lots of goodies are long gone. I'd love to find another Roush rear spoiler.
    Borla does still make the XS version.

    Dude! I was JUST thinking about Aeroturbine! what happened to that mod? What did those sound like? I've got the full stainless works deal, but I'm definitely more of a magnaflow guy than Flowmaster. it's definitely all taste...

    I think that model muffler they discontinued like 8 or so years ago.
