Review on Enhanced Performance 🚗 Walker Quiet-Flow 21054 Exhaust Muffler by Mark Jefferson

Best product I've used on my 2015 Nissan Titan. I've had all different exhaust systems on my truck from Borla to Flowmaster Flow FX, fuel economy went down with all the other mufflers. I went from 350 per tank to 420 per tank which is a huge improvement. Now I'm enjoying my truck again, there's no more hum in the cab, it's quiet and has better fuel economy per gallon. I made a 2.5" pipe after the cats into a 2.5" and a 3" Y pipe and a 3" exhaust and the standard air intake is fugitive cold air which I do too killed. I also have Bilstein adjustable front shocks and rear airbags. So my truck went up 2.5 inches as well. Love the product, wish I had found it sooner, a lot of wasted money.
