Hey yall! I'm looking to make my car a bit louder and my stock mufflers keep grinding on my drivetrain so I figured I'd kill 2 birds with one stone and swap my mufflers out with some glasspacks considering that's the only mufflers I can find that can be a direct replacement, so here lies my question: I'm not trying to go "piss my neighbors off loud" with stock cats and resonators in place, does anyone know generally how loud this will be, I'm open to suggestion if anyone has a better idea cheaper than a cat-back

How are your mufflers grinding on your drivetrain?

Glasspacks generally tend to be loud.

Glasspacks will sound horrible. Something like this would be a much better bet if you want better sound but not stupid loud.

You may need new hangers.
And to further that point, if the hangers were failing, wouldn't that drop the mufflers even further away from the driveshaft? Not sure I understand how a stock system is touching the driveshaft. I'm assuming he still has the stock two-piece driveshaft. Maybe a hanger got bent up at some point?

Yep, only aftermarket piece I've got so far is rims, shes been garaged her whole life too, so I've got no idea what exactly is the cause

I'm running 18" packs, only disturbing when you want them to be.

Pics of said rubbing?

Well, unless that exhaust pipe is moving A LOT it isn't the rubbing source. At that point the driveshaft is fixed, it isn't moving up and down. And the exhaust hanger looks to be in good shape too. There would be a witness mark on the exhaust pipe and again, if it was the source of the rub I'd think the witness mark on the driveshaft would be wider. I'd look ABOVE the driveshaft for something that may be rubbing.

I did a dual in dual out flowmasters muffler where the resonator is and just straight piped it out the back(used most of the stock exhaust). It's not loud for the neighbors at idle but when applying some pedal it has enough noise.

Seems this would also work on an 04. The muffler also acts as a resonator.

I had a custom 2 and 1/2 inch stainless exhaust installed from the cats back weld it in with no mufflers and it's definitely not too loud. I definitely don't want to piss off my neighbors but when I start up it's got a nice rumble and when you are out on the expressways it sounds more or less like European V8. Definitely not too loud when you're up 60 70 mile per hour range though.

I have Borla gutted mids and had glass packs on. Had a set of flowmasters put on to pass inspection. The flowmasters are much less socially acceptable than the packs. Go figure.
