Just curious what you guys think my benefits from a 4 inch exhaust would be by lookin at my stats. Power, egt's etc... Any help is appreciated.

I installed a 5" exhaust on my truck with far less mods than yours and I noticed a real power increase and lower egt's. I love mine although its a little on the loud side ( no muffler) I don't have any hard numbers to refer to, maybe someone else can help you on that end, however an exhaust upgrade is a must in my book.

Thanks for the input, mines loud also I got rid of the muffler and converter but its still just a 3 inch.

No power gains. But nice sound.

Anything you can do to lower backpressure in the exhaust is a huge help. These trucks want ZERO backpressure. 5" isn't really needed, but it shouldn't hurt anything. 4" is plenty until you're at silly high power levels (600 or so, I bet).

no power increase that you can feel. i never noticed a major drop in egts either. only reason i can see replacing it is for sound
