hey guys, I have a 97 12V cummins, STD cab long bed. Someone at one point hacked out the stock muffler and *coughs* welded in a dynomax. The welds are all rusted, and never penetrated and its all rusted back anyway. So I was just going to get a 90 degree elbow, some strait pipe, and go right up through the bed between my tool box and bed, All the way in the corner so i can still fit drywall in, and go strait up. Any opinions?

 

I dont see any reason why that wouldnt work. If the exhaust is rusted and rotten you could get on Ebay and get a 4in exhaust with a new downpipe and all (mine was less than $260), buy a seperate 90 degree elbow from somewhere else and use the extra pipe for your stack.

 

ya, i dont see why that wouldnt...

**check your local laws, vut uf you have a turbo (which you do) you dont need a muffler. the turbo acts as the muffler

 

im looking to do the same thing. but the guy at the diesel shop wanted over 250 for making it work with my stock down pipe, what all do i need as in parts and pipes to make this work, i have a 5" stack in my shop just begging to be put on.

 

ok what i did was get 7" pipe and then made a base plate that is 1/2"thick. burned out a 5" hole for the 5 to 4" adapter and ran 9" elbow at the bottom

the stack gets bolted to the bed

i hope the pic helps

 

you can buy these parts seperate at yer local truck shop, you will need a sweeping elbow and a 4 to 5 adaptor and some pipe thats all

 

i just put that same set up (8" stack) on my rig about a month ago and i love it, sounds awesome, and looks great in my opinion

 

looks good man...

 

I see no reason why that would not work.
