    so, I just got Virgil's old mufflers, and the more I think about it, my truck will be ridiculously loud with them!! So I've been thinking about maybe putting a flowmaster and then the magnaflows I just got as a resonator... what do you guys think about this?

    Actually magnaflows arent as loud at idle as you are thinking mitch. Mine is pretty mellow unless I really stomp on it. I stay just throw the mags on there and let it bump. Nothing wrong with loud. You got a good system in there anyway

    I also have the ultra flo x.. looked like a great idea thought it would sound great eh for my dad maybe... I do like the rumble you get when your cruising and let off the gas when she coasts down. I'm thinkin about long tube headers 2.5's into an H and then dynomax bullets.. I don't want to sound like a straight pipe pile of crap but i don't mind if you hear me coming keep me occupied when I'm on those long trips and there are no radio stations

    well, just picked it up from the exhaust shop. WHAT A DIFFERENCE!!! it sounds soo much cleaner and crisper at WOT and a little louder at idle, but not too much. It is louder at WOT, but not a whole lot. I'm still thinking about merging the two pipes into a single 3.5'', but idk. but i love the new exhaust!!!!!

    I had those same mufflers on my 6.0 with, and when I put my lt's on I still wanted something different. So I went with a single aero turbine 3.5", and it's pure sex way better than the magnablows.

    ^^^ really?? i love the sound!!! its awesome!!!!! i just want to put a real small muffler on there to quiet it down a little, nothing major tho...

    and i forgot to say before, but he moved the o2 sensors to the collectors, and the CEL still hasn't come back on, so maybe that was the problem!!!
