Out of curiosity,why did you go with a 4" exhaust?

 

because i use to have 3" and factory 6.2 exhaust is 3.5"
so why not go with sectioned 4" dmax tailpipe when it's free

plus i plan 1 7/8" headers with custom mandrel bent Y pipe and possibly p&p heads later on

 

Also 6.2L love to dump air I gain a solid 17rwhp and 11rwtq doing this NA untuned

 

this

 

i wonder what i gained e.t wise considering we went from 1* of timing to 10* from a dig thanks to Area47

 

Still cant get over how stupid high up the NNBS's frame sit off the ground with a flip kit.

What's the length on that muffler? The one that came with my durtymax kit was 15" and was basically worthless.

 

I have no idea but i can find out for you tomorrow.

 

Sounds good! Still loud but not obnoxious. Any cab drone? Did you have any drone before?

 

No drone or rasp with this setup. The old setup had rasp.and thats it other than a higher pitch tone at cold crank up. It is louder than i was going for but honestly im happy. I may put a 4" tip.out the side like a factory truck to cut off any cab noise it may have that i dont notice
