    Cherry bombs are a straight through design. Thrust makes the same thing, they just call it something different.

    don't get thrush. they are junk junk junk in my opinion. cherry bomb(straight through) will be louder than hell. I took mine off and put a a set of super 40 series flowmasters. Flowmaster is the best, a bit pricey but the best and they are heavy duty not cheap tin. will last a looooong time. worth the money. Sound great and don't rob performance.:tiphat:

    They both flow-thru. If you want loud noise, either one shud wrk vry well. I had Cherry Bombs on my Comet when I bought it 5mos ago; the Cherry Bombs was the first thing I changed.

    I have series 40 Flowmasters and they are aggressive sounding. The only reason I have them is because the free glasspacks deal fell through.

    I have the Red Hots by Flowtech on mine because they were the cheapest glass pack Summit had. Other than a little drone at 30-35 MPH, they sound great and are not any louder than the blow masters. My exhaust dumps down at the rear axle, later on I will get it extended over the axle and behind the tires. That should kill the drone.

    It seems every Dodge Chevy or Ford truck I hear while going down the road all sound the same and they probably all have Flow masters on them.
    I took mine off and gave them to a kid down the road to put on his Duster.
    His Duster sounds just like everything else out there except my truck.
    I went with Hooker Aero-Chambers and love them. They sound different with no drone. I have people regularly ask me what I have on there. Most of them have the usual Flow masters on theirs.
    I could tell a small difference in the seat of the pants feel also when I changed them and that was all that I changed.
    MagnaFlows are great also.
    Nothing wrong with glass packs either they just don't last all that long, especially if you make a lot of short trips.
    Wish I could find a set of the old Thrush canister mufflers from the 70's. they had a great sound

    I had flowmasters on my 74 for the last four years,and I think if I had a cross over pipe it would have sounded better...

    I'm thinking purple Hornies or Cherry bombs this time around and definitely a set of quick time performance electric cutouts

    The sound of the glass pack muffler depends on the length, and size of the pipe and how they are run. Where they are located after they come out of the headers or the exhaust manifold.
    The closer they are to the header/ manifold the louder and more pop you'll get. The farther down the pipe you go the more mellow it sounds

    I had cheap $15 18" glasspaks on for a couple years, and the sound was really nice. Nicer than the Flowmaster super44s I run now. A different sound, more mellow, and not NEARLY as LOUD!!!

    They were mounted just behind the front seats, exiting to the front of the rear wheels. It had a nice quiet sound until you were on an overpass with the cement walls beside you and all of a sudden you could feel the car vibrate. So you know even though your car seemed quiet, the cars beside you are really irritated:D

    Now the super44s are a completely different sound. The glasspaks are just a louder version of your stock muffer, in my opinion. A bit louder and deeper.

    The flowmasters add a bit of ping to it. And if you look at the flowmaster muffler design, it is basically a hollow chunk of steel, so it reverberates all that noise around in there like a bunch of pennies in an aluminum can. And dump those at the axle and you have a car that needs no stereo, and if you had one, you wouldn't be able to hear it anyway.:huh:

    That's one of the reasons I can't stand blow masters. That tinny ping. Only set that I have ever heard that didn't do that were on a 99 Mustang GT with a 4.6. The reason they didn't was he had a set of the glass pack chrome tips on it. They took the ping out and gave it a pleasant rumble.....

    Sounds like what I'm running. X-pipe just behind the trans, then the glasspacks, then exit in front of the rear wheels. It's not terribly loud, not as loud as the 40-series Flows I had on my 350 Bravada. Definitely not too loud inside the car, but you know the dude next to you hears it!
