Review on 🚀 Banks 48123 Performance Monster Exhaust System by Mark Callaham

Sounds great. Fit and finish are as shown. Spent an hour installing it. the required minimum of tools. also bought an AEM 21-8502DP Polished Brute Force intake system. YES, IT IMPROVED FUEL ECONOMY. I have a 2013 Nissan Titan, I've had 15 in the city and 18 on the highway. I ran a few full tanks to ensure the computer restarted with the new parts. I drive 40 km more in the city and 100 km on the highway. There has been a change of power. I haven't had a chance to tow a trailer with it yet. There is a downside. I have noticed that it goes into overdrive early or upshifts earlier than it should. so that fuel consumption can be improved. I contacted all major chip manufacturers and programmers. Nobody makes a programmer for this year's truck. I have to wait 4 years for one to be available. As far as I know this is the best you can do under the factory warranty before it voids it. still worth every penny.
