1971-1977 Vega exhaust notes

No Vega header is listed on this page or on the Vega LS parts page.
The parent page does carry cast iron LS exhaust manifolds whose application list names the 1971-1980 Vega and Monza.
Those manifolds come as a pair with weld-on flanges, gaskets and hardware, so your pipe joins at the flange.
BRP has not posted a Vega install guide, so pipe routing and clearance are left to your build.

Notes from BRP product listings. No 1971-1977 Vega install guide is posted.

1971-1977 Vega LS exhaust FAQ

What exhaust manifold works for an LS Vega?

BRP lists cast iron LS exhaust manifolds for the 1971-1980 Vega and Monza on the Vega parts page. No Vega header is listed.

Which band clamp fits my Vega pipe?

Match the pipe diameter. There is a stainless band clamp for 2-1/2 inch and one for 3 inch tubing.

Can I add an O2 sensor without welding a bung?

The 3 inch O2 sensor band clamp has a port for the sensor, so it suits a 3 inch section of your Vega exhaust.

Is there a Vega LS install guide?

Not yet. BRP install guides cover other chassis, so plan the Vega exhaust path on the car.
