Popular Post ranchhopper Posted December 12, 2014 Popular Post Share Posted December 12, 2014 I have been working for days putting on a new exhaust in the damp nasty weather caught a cold in the process but I think I have it where I want it and achieved the look I was after. I fabbed up some brackets out of steel I had laying around hours of fitting measuring welding than taking it all apart and painting them these stacks are really attached solid I couldn't believe what that little piece of steel flat stock bolted under the hand rails does to stiffen it all up. I have the exhaust running down the frame rail its attached rigid to the frame I will be welding up a bracket to attach the Y pipe to the frame cross member tomorrow all stainless steel hardware took the rusty bolts out holding the hand rails to the cab and reattached them with stainless steel bolts and washers with any luck it will be finished tomorrow. 7 Quote Link to comment https://www.bigmacktrucks.com/topic/38085-dual-straight-exhaust-near-done/ Share on other sites More sharing options...
Wobblin-Goblin Posted December 12, 2014 Share Posted December 12, 2014 Nice R Model and nice job on the exhaust. I just did the exhaust on my '64 B61 today, too. What a difference.

MACKS Posted December 12, 2014 Share Posted December 12, 2014 Looks great but not so sure about mounting it rigid to the frame and the cab,you will need some room for flex and movement no?

ranchhopper Posted December 12, 2014 Author Share Posted December 12, 2014 Its a four inch exhaust the engine has flex pipe coming from it to the pipe mounted to the frame then the Y pipe is mounted to the frame the cab is mounted solid on rubber bushings so not much flex there but I added stainless flex pipe from the rigid mounted Y pipe to the stacks so any flexing will be taken up between the Y pipe and exhaust stacks.

Popular Post ranchhopper Posted December 13, 2014 Author Popular Post Share Posted December 13, 2014 Im getting the truck ready for parade season next spring I have the fifth wheel sitting in the shed Im going to section out three feet of a fourteen foot cargo bed this spring and weld it back together paint it the same color as the truck add some aluminum diamond plate to it and mount it to the frame. I am going to make it removable so the fifth wheel can be reinstalled at any time Im in the process of machining oak slats for the troop seats in the cargo bed this truck will be used to transport military veterans in parades through the summer and haul toys for the toys for tots rides held in our area. Just before Christmas in the coming years it will haul stock piled food and toy donations from our village hall to the lions club where it will be distributed to the needy as we used to do with my military truck. I wanted a truck I would love to drive and could be proud of and could be put to good use helping others this truck will fit that bill perfectly. I know as in other hobbies there will always be the purists who would not want it changed at all and that's why everything I take off this truck will be saved and stored for reassembly if it comes to that someday but for now Im going to enjoy it. 5 Quote Link to comment https://www.bigmacktrucks.com/topic/38085-dual-straight-exhaust-near-done/#findComment-270224 Share on other sites More sharing options...

Lmackattack Posted December 13, 2014 Share Posted December 13, 2014 Looks good. I fabed up that same set up on my RS700L. I have air ride cab now so had to mount the stack bottoms to a y pipe then add flex under the cab. I also did not use the roof rail mount as it was causing issues in the sheet metal and I could never get the stacks to be perfectly straight.

rsb502 Posted January 2, 2015 Share Posted January 2, 2015 New exhaust always looks good, 4" stacks should make that sucker bark for sure.

Charlie Hatfield Posted January 2, 2015 Share Posted January 2, 2015 A few years back, I helped a friend change his "H" model from a muffler to a straight stack so we could sound like the "Macungie show". I didn't think about being the passenger in the truck, but realized the first time out that wasn't such a good idea. "What did you say"? or "Huh" 2 Quote Link to comment https://www.bigmacktrucks.com/topic/38085-dual-straight-exhaust-near-done/#findComment-272824 Share on other sites More sharing options...

2stacksuperdog Posted January 2, 2015 Share Posted January 2, 2015 We put starlight 4" on our superliner. Old 350 sounds great. Not too bad but enough to be noticed 1 Quote Matt Link to comment https://www.bigmacktrucks.com/topic/38085-dual-straight-exhaust-near-done/#findComment-272839 Share on other sites More sharing options...
