Massive improvement from what I had
"This is a massive improvement over my old exhaust, which was rusting away at the tip. With this being stainless, I'm hoping it will last much longer. The sound is amazing; there is a little bit of droning that can be heard during a small rpm range when accelerating, but other than that, it sounds great. It's not too loud in the cab, and you can hear the turbo whistle much better. I plan to get an S&B CAI later this year for my birthday, which should give me more whistle and improve the airflow even more. The truck definitely has more power now. I'm not sure the effect on my mpgs yet, as I haven't been on a long enough trip just yet. I'm sure it will not be as good for the first few trips because I know I'll step on it a little to listen to her."
