Glass packs or flowmaster

**ArmyRangers2015** · 03-11-2012, 02:22 PM

Im having trouble deciding whether to get glass packs or a flowmaster. I want know which one is loudest

glass packs would definitely be louder...i run with stock manifolds and cats with an slp y-pipe and an electric cutout with no muffler. basically like a straight pipe set up with a cutout...its fairly loud

Welcome. Glass packs are louder then a flowmaster system. Do you really want to live with a glass pack system ?

Id roll with flowmaster instead of g.packs.. G.packs are to much for me lol.

I know it wasnt one of the options, so maybe this is no help. imo, slp loudmouth.

Welcome fellow Hoosier.
Glass packs would be louder, and most here will say the Flowmaster for our F-bodies barely flows better than stock. Sounds great, tho!
If you want loud, get a cut-out on your I-pipe, to have loudness on demand.

what's the rest of your exhaust set up and what are your plans for the exhaust if it's still stock? Do you plan on headers with no cats or anything like that down the road? I would factor all this in before buying the first piece. A cutout is pretty damn fun to have so I personally would go with a quieter muffler to have when you need it and put an electric cutout on it for when you want it loud.

i had a glasspack on my 2000 formula....it was not too loud at cruising speeds...but it damn sure opened up when i stepped in it....

Glass packs sounds like crap IMO.....but mufflers/exhaust comes down to personal preference as far as sound goes.

If you get LT'S down the road flowmaster sounds JUST LIKE A TRUCK...Sounds good..On a F150. Plus flowmaster flows like shit.
The only flowmaster that are any good would be super 10s. That's for a nice dual system though.

IMO glass packs sound good when you first install them, but when they blow out, and that's pretty quick, you can forget music or conversation while driving.

I have the flowmaster 10 series on mine with Lts it sounds great but you can hear it coming from a few blocks away

Both my cars has true duals/x-pipe with glasspacks and they are not bad at all. My Z28 has the ms4 cam and it drowns out my buddies ss that had slp1 with the polluter cam. My ss has a mild cam and it has a nice rumble to it. Both cars of which dont have that rasp at 3k like most catbacks have.

^^^Your X-pipe really helps the exhaust out, esp w/glass packs. I bet it does sound nice. I had a vehicle once with some long glass packs, sounded great. I also had one with some short glass packs, it was pretty obnoxious until I fabbed an H-pipe for it. Yours on the Camaros are dumped before the axle?

**BashamWS6** · 03-26-2012, 06:09 PM

Yea i had both mine stopped at the axle. My only complant is with my cars lowered the glasspacks drag a little bit out of my driveway.
