    Re: May have to swap out my mufflers;......

    How loud is it on the “Sally” scale? 😁

    I had 2” full exhaust with tri-y’s and 2” turbos for many years.
    This was with factory installed sound deadener…and some missing pieces on rear floorboard too.
    It was fairly quiet.

    Several years ago, a full exhaust system with Hooker full length headers and Summit 2-1/2” turbos.
    At interstate speeds, interior conversation was limited to loud talking.

    After Rockwall Bash, I had a set of 2-1/4” Magnaflow’s replace the Summit turbos.
    Conversation and music (when chosen) is mucho besser.

    Last 2 combos have the ACC sound deadener kit (interior/transition hump/gas tank) and the ACC mass backed interior carpet.
    I still don’t have sound deadener applied to roof or “c” pillars/sail panels.All combos have been with true dual exhaust as well…no crossover (H or X).

    Hope this helps.

    They may be simple; but, I favor Turbos.  Mine happen to be Thrush Turbos.

    1968 T-code Coupe with a 302.  Nice car, no show stopper for sure, but I like it.

    I have Magnaflows on mine and I like them a lot. They are very mellow/quiet and idle and cruise but have a nice growl when you get on the throttle.

    Re: May have to swap out my mufflers;......

    I had a 2” system with ‘tubo’ mufflers.  Switched to a 2.5” system with Magnaflows.  I can say that I didn’t notice a sound difference between the two.  As there were previous posts regarding mufflers and noise level, I can the only difference my system is that I have turn down exhaust tips on both setups.  I’m not saying this decreases the sound, only that my experience if different from others.

    Quiet Power, Quiet Flow...whichever....they are made in various tube sizes and lengths. I went from a 2.5 to a 2" system with a plus/minus 17" Quiet Flow muffler.  I'll try to find the part # if Josh doesn't chime in here first...he's running the same ones.  No crossover, no drone, reasonably quiet  but then everything is to me.  Good note on the throttle.

    Yes, those are too long for easy install in an early Mustang.  MS got 'em in there but it was a chore from what he said.  The ones I have are 2" in and out and the body is 16 or 16 1/2.  I get that number for you soon as I can.  They made a nice install and they sound good to me.  Not noisy but seem to let the engine breath and sound good when pushed a bit.
