well i found the flow numbers. according to dynomax it flow at 841cfm and my flowmaster flows at 373cfm...thats a big difference. and the vt is suppose to be just a hair louder than stock. might have to try that out unless anyone has bad experiences with them

What they don't say is with what other exhaust is on the vehicle.
It could still very well drone and have lots of rasp if you have no cat converters and no resonator before the muffler. I read about the VT catback systems when I was looking at dynomax and saw a few people complain about how loud it is. I went with the dynomax ultra flo catback system on my truck. I still have cats so no drone or rasp at all.
If you did end up with some unwanted noise installing a 3in vibrant ultra quiet resonator takes away just about all the rasp and drone. I used one on my old sierra with offroad Y-Pipe and magnaflow muffler. It popped and had drone without a resonator.

How loud is it? I'd be running it with not cats and with long tubes. Are they replacing it for free? On dynomax site says it has a lifetime warranty

Ya that's what I've heard. I'm assuming they got that sorted out since they have a liftetime warranty on the muffler, don't know if they had the before or not. As of recently the only thing I've seen via YouTube that people have reported has been flapper rattle after the engine has been revved up and the Rpms go back down rapidly.
