I actually run the exact same except I didn't have to notch the bed

 

Thanks.
I'm looking at putting a 4" universal kit together.
And offering with our turbo kits.
We have had several customers over the years ask which kit.


transition 3-4". DP-4.0"
Straight sections downpipe to muffler
4" muffler perforated core
Up and over rear end
Pass side rear exit.
All the hangers and clamps

 

I dont see the point. 2500/diesel catbacks are a direct fit and are cheap.

 

No they are not.
I have a 2500 kit and it had to be modified to fit my
Rcsb.

 

i run 3" from turbo to underneath truck and then 4" all the way back to a dynomax bullet muffler and dual 3" tailpipes

 

I installed a mbrp diesel catback on mine with hand tools. YMMV.

 

Great,
Mbrp is what I have here.
Again RCSB. It was not a direct fit.

 

4" off the 3" downpipe to a diamond eye muffler, dumped before the axle.

 

3in cutout right at the bottom of the dp
3in back to a huge magnaflow stainless muffler
3-4 smooth transition out of the muffler
4 inch tail pipe section over the axle and in stock location.

Do u guys really think you need a 4 inch exhaust? I don't did a tail pipe because I hate the way exhaust tips look like. I would think most of us with the smaller kits like 70-76 would be fine w 3 inch. You guys w monster turbos w 3.5 or 4 inch DP will def need larger exhaust pipes.

Great idea trick rick

 

Being a universal kit.
I can add a dump at the axle option
have a few other ideas.
4" isn't needed unless making well over 600hp.

Thanks Choda,
we are getting closer ever day to what I want as a final product.
