that is the question. got any thoughts on which is better. pics.

 

Stacks, much better sound and look. DO IT, you won't regret it.

 

Or you could do both. There's a kid that goes to the high school out here that put dual straight pipe mitre cut stacks out the back of his 93 lifted 7.3 PSD. I'm not a fan of the way PSD's sound, but his actually sounds pretty nice. The big 7" stacks really make his Powerstroke Growl, sounds mean. My bed is already too short as it is, so i'm not a big fan of stacks but i love the sound of 5"s and up on a Cummins. What i'm thinking about doing is getting a system with a 4" downpipe, 5" straight pipe to behind axle, and then getting 6" semi turnouts out each side pointing in an angled back/downward fashion to really make the ground rumble. Not to mention keep the bed of my truck a little cleaner from soot. I think it would be pretty neat and fairly loud. Louder is always better right. lol.

 

i,m 4" turbo back straight piped to a 7" stack. laud as hell gets alot a looks and when someone is tailgatin ya kick her up a gear lug it down **** off the 5 cars behind ya

 

it's strait pipe for me. The wife won't let me go with a stack.

 

stacks are cool sometimes. But for driving alot it get's old having that exhaust right behind your head.

I run a 5" straight pipe and 6" tip out the back. Sounds good and is nice and loud when you go past buildings. And can smoke out the road with ease if you have injectors and such.

 

Same here. I straight piped the stock exhaust.

 

i say stacks you wont regret them i love mine and will nevr take them off

 

I haul a lot of nice shiney motorcycles in my truck so stacks arent really an option. The bikes would probably get covered in soot and gunk over time.

 

I've got 5" from downpipe back to a 6" tip, very loud (sets off car alarms at will, and it has a nice deep rumble to it.

 

Do you ever plan on having a camper? How much do you use the box of your truck? I like the looks of stacks on some trucks but I would never have them and now a days it seems like everyone has them anyways

 

Speak for yourself! I never get tired of the sound. Its the middle of winter and I still hit the button and open up my rear slider just to hear that beautiful sound.

 

5 inch straight pipe to 2 six inch miters......... I dig it!!!!

 

Definately do not go with stacks. They look ridiculous on a pick up truck.

 

If you don't mind lots of noise, windows up or down, go with straight pipe stacks. They sound just like a rig. I would never change my straight pipe dual 6" turnout stacks.
