CHolman said:You know, all these new trucks have 4 inch already, all you need is a high flow muffler... If your really going to "up"grade, you have to go 5"... With these new downloaders and pressure boxes, I would just get 5" from the get go... You say "I'm not going to go crazy"... Then you go to the drags, pulls, or shows and then your hooked, you want more power... One thing leads to another and before you know it your pushing 600 HP out of your common rail...
JasonCzerak said:I went cheap. I invested around $200 in my setup. Well, they did mess up and send the $80 muffler part for free so that parts a bonus.
S-bend Muffler delete $80
3 band clamps $33
10 feet of napa 4" exhaust tubing $80 I think. ( have lke 4 feet left
Welding the napa pipe to were the cat was cut off $20 ( I suppose I could of unclamped this, but I'm a moron some times).
05mxdiesel said:I did the same as you but instead of the s-bend muffler delete I used flex pipe. I sanded and painted the napa pipe to keep it from rusting, but the flex pipe sure is an eyesore. I also cut off the hanger off of the old cat pipe and welded it on to the new pipe.
CHolman said:Well, before I went with stacks I went to www.bigexhaust.com and went to the shopdiesel exhaust and got their 5" turbo back with muffler delete pipe for $295... That 5" down pipe is awesome!!! I was stright piped before that and after that 5" stright piped exhaust I didn't "believe it or not" have "as bad of drone" as I did with the 4"... It shows 4" pipe for a down pipe on the diagram, but it's 5" down pipe, at least with the kit I got. :-laf
