Holy smokes!

Big pipes for the Cummins. This is a 4" set from the turbo back we are installing on Tom’s truck. It splits into dulls after the muffler. This system is much bigger than the stock stuff.

All in all it fit pretty good the only problems being the claps that were supplied with the kit were for four inch pipe. That would be fine if the pipe were expanded to four inch. But this shit was four inch before they expanded it. Dumb asses!

The manufacturer claims 25hp gains and 25 to 30 foot lbs tq. gains with 5 to 10 mpg gains. Will see.

Tom looks a little confused.

And a quick look at the old.

Impressive stuff ain't it. We have installed a chitload of 4" systems but have yet to do one with dual tails. The cost of the dual system over the single scares most folks away from it.

Those big pipes really wake a Cummins up! [smilie=e:

Were they linked in or were they attached?

Lemme know and I'll see what happened..

My neighbors son in law has a 5 inch system on his powerstroke furd F-350, he pulls a 38 foot fifth wheel trailer and a 20ft fishing boat and still runs 85-90mph on the highways. I think he has it chipped also.
