well iv been thinking about running a 5" stack my truck is a reg cab. Would it be extreamly loud in cab and if so should i go whith a bigger stack. ill be pulling some. i dont really want to mess around whith a turn up on exaust but i would still like to beable to here myself think in the cab goin down the road. thanks for eny input

 

for a regular cab Im willing to bet it'll get pretty noisey, but grand rock offers an internal muffler that sits inside the stack itself or you can do what I'm think of when I get stack is to add a muffler before the 90* the goes into the bed,

 

LOUD....thats why i didnt put stacks on mine

 

I have a 54" Magnaflow muffler under mine and the stacks are still pretty loud....sometimes too loud..........especially when towing

 

i was also wondering on all the suet thats prob spelled wrong after a rain so on.

 

if you get straight or mitre cuts then you'd probably want to get rain caps or something to cover them because when you start up your truck after it rains it gets soot all over your cab and bed

 

come on thats y u buy a diesel so u can make it loud come on guys

 

A buddy of mine had 6in stacks in an extended cab, and he said they were loud...especially going home after a night filled with adult beverages, and passing out on my brothers couch!

 

I had thought of the idea of stacks, but I find no reason to be bombarded by a rumble from the rear, and a whistle from the front. One is inevitable, the other is just more holes in the tin work. Also, in my opinion, stacks are kind of s red flag to cop saying "here I am, watch me close".... jerks.
