Part 1 done, the muffler delete...... Zero change in sound.... But, it now has a tail pipe that exits out from under the truck insted of resonating under the bed.

Yeah you get a set of those cats out and it will sound better.

I would avoid totally straight piped, it sounds like something trailer trash would drive IMO.

Yea, I'd only strait pipe a turbo Diesel..... It will probably stay like this until I do longtubes and a cat back.

Hey fangs, serious question, what is your reasoning? Why only a diesel?

Because the turbo wants as little to no back pressure..... Where naturaly aspirated and supercharged engines like some back pressure..... If I turbo'd my truck it would probably be strait piped after the turbo.

Thats why Scobar mentioned to remove 2 of the 4 cats but not all 4..... If I could, I'd delete the 4 cats and put my 14inch SI/DO magnaflow back in.

Ahh ok I thought u meant straight piped like I have true dual straights but all 4 cats still. I know understand why you wouldn't on a gas non turboed motor.
