Another Cat Back Question
OK, I know all about the Corsa, Billy Boat and Borla systems. I know they are supposed to be the best systems out there, but I have been looking at the SLP Loudmouth and Loudmouth II and the NXTSTEP system. Anyone have experience with any of the three? I have an '07 A6 coupe with American Racing long tubes and hi-flow cats with the stock mufflers. wanting to wake the sound up. I have read that the SLP Loudmouth beside being just that loud, it has a bad drone, The NXT's don't sound as loud as the SLP's and not sure if the drone is less. Also I was wonder what the difference in sound and drone it between the Loudmouth and Loudmouth II.
The car is not a daily driver or does it go on long trips so it is just a play toy around town.
Thanks

If you already have a aftermarket x pipe you need a axle back exhaust. The only thing I know about slp loudmouth is it is properly named. Corsa I can tell you about but even the Xtreme is not as loud at loudmouth.
