Tongue Mufflers
« on: March 26, 2019, 05:18:25 AM »
I have aluminum stock to make my own tongue mufflers, where do I find the preasure fittings for muffler preasure. Any help  would be appreciated.

TIA

Du-Bro, hobby shops have them. Du-Bro also has 6" aluminum exhaust extension stock p/n 213. All you do is cut it to length and drill and tap the bolt holes and cap the end.
I may be wrong but I doubt it.

this is the Du Bro one . Had one , which was usefull , as it ' Bolted In ' a muffler .  But NOTE ,

the Threads NOT right down . Tho it has a nut , so ye dinnae need to TAP the Fred .  However FOR a tapped thread , Youd need a Thick Washer .

Some Stores have stocks of say OS or ST Pressure Take Off fittings to replace backplate bolts . Typically 3 m.m. thread . Needs Hole Tapping .

Theres 10.000.000 differant  ones on google 'Du Bro  pressure Fitting ' . So use watevers handy .
BAR some like smallis holes , not the big OS ones in their muffler fittings . ?
