When we ran a full service chassis fab/turn-key hot rod shop a number of years ago, it was always useful to have threaded things around to weld into the frame for some kind of mount, etc.
Here’s a list of all our threaded things for your reference:
Buy 10 of one part number, get 10% off.
Buy 40+ to get them for 40% off! Sorry, no additional discounts applicable.
NEW: A double hanger designed as a side mount, with a built-in gusset that gets folded by hand and welded. #213463
Frame brackets for mounting your exhaust, in one and two hole configurations, are cut from 10 ga mild steel.
Stainless hangers are 316 2B (316 contains 16% chromium, 10% nickel and 2% molybdenum. The "moly" is added to help resist corrosion to chlorides (like sea water and de-icing salts)).
Exhaust bracket holes are 11/16″ for use with our grommets. Frame bracket holes are 3/8″.
21348: 10ga mild steel, 3/8″ diameter hole is 2-3/4″ from the top edge.
21346: 10ga mild steel, two 3/8″ diameter holes are 2-3/4″ from top edge and are on 1-1/2″ centers.
213463: 10ga mild steel, two 3/8″ diameter holes, 4” from furthest hole to edge.
21347: 316 2B stainless steel, with an 11/16″ diameter hole (for #GR121 grommet) 2-1/2″ from the top of a 2-1/2″ diameter exhaust tube.
213473: Identical to 21347 but for a 3″ exhaust tube.
21347M: Identical to #21347 but cut from 10ga mild steel.
21345: 316 2B stainless steel, two 11/16″ holes (for #GR121 grommet) are on 1-1/2″ centers.
21345M: Identical to #21345 but cut from 10ga mild steel.
We highly recommend a flex pipe between your headers and the first hanger location. This will greatly reduce the stress on the hanger.
See related parts for a hardware kit. A threaded bung can also be used to mount the exhaust hanger to your frame.
