Last week I finally got 5in straight pipe, ran over the back axel, I love the way it sounds and how much it drones but people have been telling me it isn't loud enough outside the cab... So now I have the goal of making my exhaust loud enough to set off car alarms!. So I was wondering what yall thought would be louder a 7in 36in long stack out the back or a 7in 18in rolled edge tip, or maybe if there isnt much to gain and just keep it where its at?.... I would love to hear yalls thoughts on this. Thanks for reading

 

I would just keep it the way it is. IMO. I have a buddy with 5" tbe on his 07 5.9 and you can here him coming 5-6 blocks away..

 

I have twin 7's straight piped through a 5". No emission laws here though. I found that stacks in the box with a sliding back window are loud. With the solid back window they are tolerable. It will drone more on the highway with a 7" tip. If you want loud go with the stacks. I get way more thumbs up and smiles from people staring at the 7" stacks then I ever did driving my blown quarter mile mustang. Give er'

 

Go with the stack i had 4in exhaust it sounded good but i put a 5in stack it sounds great and you can hear the turbo way louder
