S10 Blazer LS exhaust notes

With BRP headers on an S10 2WD, the guide says the steering shaft has to come out to fit the driver side header.
The S10 2WD kit uses the LH8 oil pan.
High-mount accessories are required. The guide suggests a Corvette balancer and water pump with Kwik Performance alternator and A/C brackets to leave room for the radiator.
No header for the S10 Blazer is listed on this page or the Blazer swap page right now.

Notes from the 1982-2003 S10 2WD LS install guide, which is titled for the S10 2WD and does not name the Blazer. Part sizes come from the product names.

S10 Blazer 2WD LS exhaust FAQ

Does BRP list headers for a 2WD S10 Blazer LS swap?

Not on the Blazer pages today. This subcategory has the clamps, reducers, O2 clamp and header bolts.

Is there a clearance issue with the driver side header on an S10?

The S10 2WD guide says that with BRP headers, the steering shaft must be removed to install the driver side header.

Can I add an O2 sensor to a Blazer exhaust without welding?

On 3 inch pipe, yes. The 3 inch O2 sensor band clamp joins the tubing and holds the sensor.

Which accessory drive keeps the front of the LS clear in an S10 Blazer?

High-mount accessories are required per the guide, and it and says Camaro and truck LS drives stick out far enough to hit the radiator and fan.
