I'm finally going to replace the stock axle-backs. At one time I thought about the Roush, the 2012 GT500, the 2013 GT500, the Borla Touring, etc. On paper the FRPP Touring sounds like what I'm after, low, throaty, "old school," good WOT growl, but CA legal. Plus I like the shiny tailpipe and that they're 304 SS throughout. However there's very little on reviews of this muffler. Anyone here heard them/own them? Also, FR seems to be the only one that states whether their mufflers are 49 state legal vs 50 state. Are the rest all 50 state? Questions, questions...
