   Anyone running the FlowFX mufflers.?? And are yous happy with the sound and it's level? Gotta practise something with this noisy chocolate-brown turd before we go deaf, with it's no name copies of I doubtable Flowmaster twoscore's at the noisy end of Holley's decibel scale.

   Sounds similar you might be better off with a turbo muffler. Both Dynomax and Pypes brand a very dainty turbo muffler. Here are some audio clips-

6. im using the flowFx'southward

   switched from the FM 40'southward

   sounds very punchy without any drone or large metal sound

   i liked the 40's but i only needed to fab up an unabridged frazzle when the tko went in

   If you desire information technology quieter, and you dont have room, or dont want to go to a bigger longer muffler, i think you are stuck with a turbo style triple laissez passer. I think a same-size straight-thru wont be whatever quieter, and if you dont have room for a 3 bedchamber flowmaster in place of the two chamber knockoff you take now, a chambered muffler wont make much deviation.
   I gotta agree with CMCE, i recollect you demand a quality turbo, with ii 1/two tubes all through, no neck down. If you have room frontwards of where your mufflers are now, longer is quieter.

   I'thousand merely going by Flowmasters own chart.. same size and they show the 40 the loudest, then Super 44, then Super 40 a bunch of others and then the FlowFX midway in their LOUD to Quiet chart.

   The way the front pipes were bent I tin't cutting them to get them in a straight on muffler line up if I become longer.. and I'thou not doing a total arrangement, unless it includes going dorsum to HP stock manifolds..

   I've got Dynomaxs on the Belvedere, pretty tranquility, no droning, nearly too tranquillity. 2 1/ii" get-go in, centre out, looks to be about the same dimensions as yours.

    Is adding resonators an option? Would be much cheaper than buying two new mufflers and would tranquillity down your exhaust note considerably, if that's what you want.

    I got some put on after the mufflers on my 64 Newport and they are astonishing! Yet has a mean tone but information technology is not what I would phone call loud. No drone at all in the motel.

18. Flowmasters suck.
    Accept them on my pro street challenger, and they are ever scraping even though the ride height is close to stock.

    I am going to completely redo the exhaust (except the headers, Hooker super comps!) because the previous owner was stupid and put the virtually restrictive exhaust ever on a 900hp blown large block, must impale 150hp... I guess he was thinking velocity? He put 3in to 2.5in adapters on the header flange, put giant restrictive Flowmasters on, and then necked it down once again past the mufflers to a 2in tailpipe. No x or h pipe, no cutouts.

    I am going to put a full 3in exhaust with cutouts and glasspacks before Carlisle.

    I'm non even going to deal with it on the Charger. I'm just going to put 3in Purple Hornies right on the back of the headers with no tailpipe.

    Let us know how the super turbos work out.

    The FlowFX mufflers expect similar to the Dynomax welded ultraflow I had on a 1968 440 Dart. 2 1/two" Pypes brand full frazzle with X piping. They were too loud and had a drone. I thought about adding glasspacks equally resonators in the tail pipe similar @Garngie suggested but never did.

    My trouble with super turbos as well beingness restrictive, is one expert backfire could destroy them.

    I have used a few sets on Dynomax Super Turbo ii.v" mufflers, and similar them. Fairly quiet, simply that seems to be what I adopt as I age. I used a prepare of them in 3" on my Bee and they are noticeably louder than the 2.5" versions. I used to run Flowmasters years ago, merely the noise and drone collection me nuts later awhile. Tried their l series once, I think it is listed as a RV application. That was much improve than the 40 series, merely still kind of obnoxious.
