DynoMax's Catback w/ Troyer is the cat's A$$
Last week I installed Dynomax's Dual Exhaust witht the Ultra Flow Welded Muffle on my 01 Supercrew 5.4. WOW I love the low tune rumble. Just what I needed to fall back in love with my truck!
I also have and Air Force One from Troyer and waiting for my tune for my Xcal 2.
