I recently purchased this 2008 GT that the dealer had changed the mufflers on.

Can anyone tell me what mufflers they are from the pictures?

Also, I am trying to find out if there is anything I can do about the drone that is particularly bad with the windows up at 1500-2000 RPM.

Thanks in advance for any help!

Flowmasters, although they look like 1 chambers.

Congrats on the purchase! :)

Anyways, there isn't much you can do about the drone besides replace them with another type, if I'm not mistaken. :so

If they're the Flowmasters for the GT's, they are black and have 4 inch stainless steel tips. There will be a small hole in the bottom of each tip for drainage. But the quickest way to tell is that they will say "Flowmaster" on the top of the tips. Those look like my Flow's but it's hard to say. You can also look for a part number, 17410, on the mufflers themselves.

Thanks for the info! I will check them out closer.

I must agree with what someone stated earlier, these look more like a single chamber Flowmaster. I think the dealer threw these on and welded on some tips. The loud droning you hear at the low rpms is barely heard on the Flowmaster GT mufflers on a stock setup since Flowmaster designed them to have minimal interior resonance.

Those are defiantly Flowmaster single chambers. They are NOT street legal, they are race only. I had one of them on my '00 Dodge Dakota v6 years back, you could hear the truck coming over a mile away. I had it on my truck for a day before changing them out to a dual chamber.

I'm voting Cherry bombs too.
The first picture definitely looks like the right ones.

Now what? I love the sound, but I don't love the interior cruising sound. What suggestions are out there?:headscratch::headscratch::headscratch: (money is always a concern:scratchchin - darn it!)

They look like Flowmaster 1 chambers but if they are they will have Flowmaster stamped in the case. No writing = Cherrybombs or knock offs.

You could try having a set of resonators welded in further up stream of the mufflers. I know at least Stl has done that. I had FRPP "Stingers" on my car. I loved the sound but after a few months couldn't take the drone. I sold them and went back to stock. I plan on leaving the exhaust alone for now and spend my mod money else where on the car.
