Heck,
Guys, all you's need to do is run a 6" pipe straight out the top of the hood! Why all that extra pipe to get it behind you. With it in the front, you can see how black the smoke is!
I would tend to think that a bed stack system would be LOUD, as they are right behind your ears! Some complain about droan and noise on FULL length, to the bumper systems. Imagine that 10x's louder RIGHT BEHIND YOUR EARS!
Here's a thought on the drivers side dilema.....Just make it a SINGLE stack
No need for DUAL's unless you have DUAL turbos. Single 5" stack out the passenger side bed corner. Most of toadys big trucks have only ONE anyway.
As rednecky as all this sounds, it still is kinda cool looking if done properly.
