I agree that the ss exhaust alone is not a great upgrade but once you add the CAI then it becomes very much worth it. I've found that opening the intake makes all the difference in the SS exhaust sound on the LFX as well. However I'm still looking for opinions on an axle back system to compliment the SS exhaust on my LFX. Thank you for your input as I was concerned that I made a bad choice. On a side note my mpg's on the highway went up by 2 since the exhaust and intake upgrades.
