We have a 1992 Dodge Cummins turbo diesel 4x4, we are wanting to take the stock exhaust off and put a straight pipe system on. What is the best system to use for this truck?

 

i ordered the diamond eye 4 inch for my 91 you can get it from summit racing and it will be delivered in 2-3 days just make sure you get the 4x4 model and if you upgraded the turbo with a hx40 flange you will have to order the hx40 down pipe
