I have true duals with 40 series Flowmasters dumped before the rear axle but it's just not loud enough for me--it just doesn't sound like all of the other vehicles with Flowmasters that I have heard. The guy at the exhaust shop suggested that it was the smaller pipe leading to the mufflers that was causing this. The previous owner had these installed and the mufflers are 2.25 inch and the pipe leading to them is about 1.625--do you think going to dual 2.25 pipe would make this thing sound any better (louder, deeper)?
