Received the mufflers yesterday and installed them today. DEFINATELY has a much better sound over the stock muffs. I can't imagine once the LT's go on what it'll sound like then. I was going to go with a turbo kit for the power adder but I had to reel myself back to reality that I just want to keep the car 600-650 MAX and leave it alone, so I will be doing a Whipplecharger and have fun. I've been smiling like a little kid. I forgot how that was to have that feeling........lol.
