Stretched out Posted December 27, 2013 Share Posted December 27, 2013 Hey guys, just bought a 91 Rd688 to restore. I'm going to put dual stacks with twin 13" stainless breathers. I didn't know if there were any kits for mounting the breathers or if anybody has pics of a good way to build the brackets for them. Also I was going to see if anyone has pics of how to mount the dual exhaust. Thanks for any help 1 Quote Link to comment Share on other sites More sharing options...
gearhead204 Posted December 27, 2013 Share Posted December 27, 2013 rw brackets should work hope your a skinny little guy Quote Link to comment Share on other sites More sharing options...
Stretched out Posted December 27, 2013 Author Share Posted December 27, 2013 Do you if rw's use 13" or 15" breathers? Quote Link to comment Share on other sites More sharing options...
gearhead204 Posted December 27, 2013 Share Posted December 27, 2013 ive seen both the smaller you go the more the door opens Quote Link to comment Share on other sites More sharing options...
Stretched out Posted December 27, 2013 Author Share Posted December 27, 2013 I believe the 13" would probably look/fit better. Looks like the rw breather straps are spread out a bit farther than the rd straps but I believe both sides could be changed easily Quote Link to comment Share on other sites More sharing options...

RFCDrum Posted December 27, 2013 Share Posted December 27, 2013 I've seen it done here in the US. Swishy should know the part numbers for the brackets. I think you have to reinforce the cowl where the bracket bolts to. Rob Quote Link to comment Share on other sites More sharing options...
Stretched out Posted December 27, 2013 Author Share Posted December 27, 2013 I was thinking bout putting like a 1/4" plate on inside of cowl. Got a Mack dealer looking up straps and brackets off both row and Aussie R model. Hope can come up with something. 1 Quote Link to comment Share on other sites More sharing options...

Stretched out Posted December 29, 2013 Author Share Posted December 29, 2013 Looks like real clean job. I agree the 15's are to bulky on r model Quote Link to comment Share on other sites More sharing options...
Stretched out Posted December 29, 2013 Author Share Posted December 29, 2013 Did you buy your breathers new or used. I've been trying to find used ones but seems like most every truck except freighliner has their name on breather Quote Link to comment Share on other sites More sharing options...
gearhead204 Posted December 29, 2013 Share Posted December 29, 2013 if memory serves my rw uses a strip of 10 or 12 ga. to reinforce the cowl Quote Link to comment Share on other sites More sharing options...
bobcotkg Posted December 29, 2013 Share Posted December 29, 2013 The stock steel Mack cleaners look nice painted up, or a stainless wrap on them.New ones aren't cheap and used ones are not cheap either. Good luck with your project!Bob Quote Link to comment Share on other sites More sharing options...

Swishy Posted December 30, 2013 Share Posted December 30, 2013 No sure if the cowl is reinforcedthe upstuk snorkels have a ring and 3 or 4 supports running to the outer bolt ring of the AirCleaner made of 3/8" rod Cya Quote Link to comment Share on other sites More sharing options...
