I have had my flowmaster exhaust on for over a week now and its kinda getting on my nerves so I think I want to put the stock muffs back on but my stupid ass left them at the exhaust place and they threw them away:bang: so it looks like I have to buy the stock exhaust off of someone here, I thought about buying the magnaflow but I figured it would be just as loud is this true??? I think Ill put the stock back on so if any one has the stock cat back send me a pm, Im located in WV

I don't believe that the magnaflow catback is as loud as the flowmasters. I can safely say that the MF kit never got on my nerves, and isn't annoying to my wife either. You notice it when driving hard, but not so much when taking it easy. Only think that bothers me atm is that when the engine switches back and forth between 4/8cyl mode, you can hear it...and for me right now, there is some sort of resonance causing a rattling when it's in 4cyl (and I'm assuming that it has to be the exhaust making this sound).

Coming from the guy that had way too many M-60's fired close by, I really can't hear the Magnaflow exhaust over traffic, so it seems like a "refined" sound to me.
Like Buff said, mine causes a "BSR" in my driver door when driving down the road.
Just about time to get the Z out of storage and hear a real exhaust note ...
