Thinking of doing my own custom design to my exhaust with a summitracing universal kit. welding straight from the CATS and angling right out just behind the front wheels. Your thoughts?
I have a single. If you look under a truck with a single exhaust you will notice the left (driver side) pipe after the CATS is SMASHED when it runs under the trans and into the Y. That smash takes away horsepower. Creates some back pressure from what it looks like. Therefore the purpose is to eliminate that and gain the horsepower back.Hmmm, if it has duals already it's not worth it. If it doesn't go for it. But I do not think you are going to gain as much as you think
