Mack R model dual stacks


Recommended Posts

you will have to mix and match it together unless you can get a Vin number off a R model with factory Dual stacks. Just be warned the sticker price from mack might kill you.at best print it off and use it as a guide to buy your own parts.

seams most people with R models run a pipe upwards behind the cab/ between the frame rails, then tee it off to each side. It really depends where your exhaust hangers can mount tho so start there. sometimes the driver side center fuel tank strap/bracket is in the way. First get your hangers set up then you can see where the pipes will have to travel. I saw one guy able to squeeze pipes under the cab corners but it was very tight and looked like they hit the frame when the air ride cab moved .

another option is to mount hangers to the cab. The old mack westerns did this and it worked but if you hit a tree branch with the stack it can damage the cab.

How about what Dan was looking for the other week. The box across the back that the pipes just sit on?

Jim's right. I do like the stock, classic, single pipe look. Then again I do like duals. Guess I need two trucks to cover the bases?
