4AGE 16V/20V Exhaust Header Flange w/ 1.50" Holes

Fits 16V and 20V Toyota 4AGE heads. Accepts 1 1/2" OD tubing. Ideal for building your own tubular header.

Material is 3/8" mild steel, which warps less during welding and has less tendency than stainless to distort at very high temperatures. Stainless looks pretty on the internet, but this works in the real world.

1 1/2" port holes accept 1 1/2" OD tubing, as used on an OEM AE111 header. These holes also match the ID of typical 1 5/8" 16ga tubing.

4AGZE owners: header flange must be trimmed to clear alternator bracket.

Fits like OEM, made in the USA.
