I don't have to have an X pipe do, I could bend the driverside pipe so the mufflers are next to each other and then bend the driversides back out to to the side of the truck.
or is that going to cause cause a problem?

What brand do you suggest high fow cat?

hopefully this is my last question. should I run 2.5in everything from the header back to the tips or 3in?

 

Not sure how the underside of the Ds are set up but thats how the Rams are done. the mufflers are installed right next to each other.

As for cats...carsounds and magnaflow are really good. I am always seeing magnaflow cats on ebay for 75 bucks.

I would stay with 2.5 if you are running true duals. It will help keep some of your back preasure.

 

I was just wondering which exhaust would allow for the most HP gains, the true dual exhaust or the cat-back exhaust. I am thinking about putting an exhaust on but I want the one that will give me the most power. If anyone could help me on this one I would appreciate it.
