I can't tell you but holy crap those do not sound like flowmasters. They are probably 3-chamber Flows. Sounds horrible IMO
3 chamber flows? What's that?
Chambered mufflers are called chambered mufflers because they have chambers inside the muffler to deflect/muffle the noise. Straight-through mufflers (SLP, Magnaflow, etc.) feature an unobstructed straight clear path right through the center of the muffler but the walls are packed with sound-deadening material (that's how they muffle the noise).
The more chambers in a muffler, the more the sound is deflected and muffled. Flowmaster has single, double, and triple chamber mufflers. The single chamber (10 series) sound mean as heal but are unbelievably loud (youtube single chamber flowmaster). Double chamber mufflers (40 series) are more common on muscle cars because they offer the same rumble/growl but t a tolerable noise level. The 3 chambered mufflers are basically truck mufflers.

Cool, I learned something new. Thanks! Yes, these are chambered for sure, I think that's the rattling noise going on inside. So if it's 3 chamber, what series is that? I'll prob just get two replacement mufflers either 10 or 40 series then.
If it's rattling the one of the baffles (metal pieces you see in the diagram) has probably let loose. Like I posted earlier, the original 40 series muffs are what you want. They are two chamber with maximum flow so they are louder/meaner.
The MAC Flowpaths (like what is on my car are also two chambered). The design of the chambers and whatnot results in what you hear in my vid. For some reason, there is less drone, but they sound incredible from 2500+
What do you mean only one is working?

It actually doesn't sound that bad. Needs to be much louder/meaner!
Ravins are fkn garbage!
Just an FYI, single chamber flows (1-chambers) are VERY loud! They sounds awesome at first but you might get tired of them
I'm assuming a**hole threw them on before he sold the car to me. I bet you flowmasters were on it to begin with and he took them off and sold them.
I don't mind about not having a conversation inside the car because it's that loud but I hate that backfire crackle noise. Would it still be loud like your saying even though I have all 4 cats, stock h and K&N cold air intake with the two 10's?
I thought you were ditching the stock H for an O/R piece. It wont be as loud with the stock mid-pipe
I LOVE my Magnaflows....but from what you have been saying you may not like them...
