    I have 2.5" offset offset magnaflows. I purchased them used from a mustang guy. I imagine they were for a mustang. I like it. It is not too loud.

    I have magnaflow offset/offset glasspacks as well. Thrush turbo welded glasspacks I think are the less expensive brand version of magnaflows.

    On my MGM, single 2 1/4" exhaust no muffler just the stock cats. Still was fairly quiet with a pleasant volume level.

    Yes... yours done horribly. Mine don't drone at all. I was shocked how bad yours drone.

    I've run drone masters, they drone. Just don't.

    I currently have 2.5" summit "turbo" mufflers on the wagon. I think they sound great, but my compression is lil higher...

    IMO firing order is the biggest gain for a sweet exhaust note. 302 sounds like a tractor. HO/351 sounds mean.

    Depends on what you want. I like the Dynomax Super Turbos because I like quiet exhaust systems nowadays. I'm running cats and 3" Dynomax 17792 mufflers on my 351W; but I haven't started that engine yet; so I have no critique of how they sound. I was running Dynomax 17749 muffs with the lopo; behind a full exhaust. They were very quiet.

    I'm running Borla XS on my cars.
    I don't like to draw attention with the sound at WOT. They do get a little louder when you open it up, but not enough to draw the police from a mile away.
    They do well and have no horsepower loss. They actually have a slight gain in horsepower.

    Almost always if not stock, some turbo mufflers.
    Once bought a truck that had a FM 3SI/2.5DO, drone was bad at some speeds, a glasspack ahead of it helped.
    No ... I'm not arguing with you ... I'm just explaining why I'm right ...

    Now go ... and whatever you do ... have a safe trip!

    I'm currently running some Flowmaster delta flows that I got for free on a custom bent 2" system with the two rear cats removed. It sounds good for what it is.

    When I put on a new exhaust, it will consist of BBK headers, Pypes X-pipe with high-flow cats, and Walker QuietFlowSS 2.5" mufflers with Impala tailpipes. I have a good feeling about how that will sound.

    ^^^^^^^^That will be quiet; basically the same setup I had with the lopo; except I had Summit turbos at first; then Dynomax 17749 muffs when they failed. It was quiet with the Summit turbos; so much that my Mom hated it; which is why I had to put cutouts on that exhaust.^^^^^^^^

    I've mellowed out a lot and actually want a quieter car, but still with a bit of rumble. The new exhaust will also coincide with the new engine I'm having freshened up for it: 302 block, GT40 (non-P) heads, and a camshaft comparable to a '93-'95 Cobra. It'll essentially be a Cobra engine.

    pretty sure its the Fox H pipe. Fox cars are really prone to drone issues if things are not exactly so. The black Mark VII droned pretty badly too. Whenever that thing needs exhaust work again, or whenever I feel motivated to drive it more, I'll have stock-style exhaust made up for it. Probably a little larger than factory but using the Panther routing and such. I strongly suspect that will make the problem go away.

    I suspect your right since my exhaust is pretty much the same but with the panther h-pipe.

    That was fantastic. I had a rough day at work and that made me laugh so hard I forgot all about it.

    Magnaflow 2.5" offset on my 4.6 with no downstream cats. It is a custom bent 2.5" cat back with a crossover.

    I hate it, the drone makes the car really annoying to drive on the highway. When I have some time I am going to cut them out and replace with something quieter.

    Magnaflows. No H pipe. No drone.
    I like them enough I put them on my other vehicles when they need it.

    I had flowmaster knock-offs on the coupe, but I switched to Flowmaster original 40’s(no delta flow bullcrap). There was a very subtle difference,

    FWIW, Flowmaster 40’s of any variety need to have no cats upstream and at least a little cam to sound good. Once those criteria are met, it’s like the song of my people, otherwise they blow goats.

    I’ve done glass packs in the past, dumped before the rear axle...that’s a bit rowdy. Also have done glass packs bolted directly to collectors of LT headers....that was like turning it to 10 and ripping the damn knob off. Dynomax super-turbos dumped in front of the rear wasn’t too bad, would’ve been better with tailpipes, but I like to party. The ABSOLUTE WORST was my buddy’s old ‘72 Maverick Grabber- LT headers, 2.5” pipes, Moroso spiral flow “mufflers” side-exiting with 3.5” slash cut tips. Sounded great, but on a cruise, you’d nearly go deaf.
