    Hey guys;

    I just swapped out the exhaust in my 'Stang, and threw stock GT Takeoffs on there. It's a true dual exhaust (I cut the y-pipe off and ran piping after each cat to a seperate side of the exhaust). It sounds pretty good idling, but it's not that loud or deep.

    So, after much research (e.g. listening to wonderful Youtube videos), I think that I should go with Flowmaster 40's or 44's...

    I can't decide which. They both cost the same, and I can't find any decent information on the internet about the true difference in sound between them (again, all with respect to the V6 Mustang).

    Any suggestions?

    To me the 44's sound better, I believe they have a deeper tone than the org. 40's

    If you are going with Flowmasters ^ agreed with Chaotic. It really all depends on which sound you want. Most claim that the 44's are louder and deeper but from what I have heard in person, I they pop more but aren't really to me much if any louder on a V6.

    IMO the 44's are a little bit deeper, but you won't be disappointed with either choice.

    honestly I love the sound of my setup currently. I got the Mac Off road H and flowmaster American Thunder series stainless for the GT. I love the sound its not annoying inside the car. And when you accelerate slowly it sounds like a mild modded GT, but when you punch it, it sounds like a v6 still. Its perfect for what I want and I couldnt be happier. hope this helps!

    New on here and I know my opinion means squat but I took the Flows off my 460 powered 71 F100 and put on some Hooker Aero-chambers and would never go back. Sound is much more aggressive sounding and I even noticed a small boost in power. No drone at all either.

    Here's flowmaster Super 44's with the 2 front OEM cats (removed rear cats, and put an H in) 2.5" pipe, mendrel bends.



    Same mufflers, But I replaced the catted pipe with a Pypes o/r X (no cats) and I think it sounds tons better.

    Judging by the number of his posts he has no idea what he is talking about.

    Hey De stang, how do you pass emissions with no cats? I'm just curious cause that thump thump is just amazing for any mustang, let alone its coming out of a sixxer.

    easily. No check engine light means I pass. :D

    They are made by Autometer, its a whole cluster. I do believe they are discontinued and retailed for right around $300.

    Will my car pass an emissions test if I get rid of two of the cats (fronts or backs)? Or if I get/make MIL eliminators? I doubt it'd pass with absolutely no cats... Also, is there a way to make the car "ignore" the O2 sensors? (IIRC, tunes can make a car ignore an EGR valve, but I'm not sure about O2's)...

    I want long-tubes as well, but would they easily fit with the true dual setup I have now? I assume it'd be easy as cutting the exhaust where it got welded on, bolting on the headers, and welding them up... BUT, again, how would I deal with emissions?

    Edit: I remember seeing your car a few times on Youtube, DEstang. Sounds bad-ass.
