Panman, Speedway Motors has inexpensive stainless steel blockhugger headers. If you have a tig welder or access to one the rest of the exhaust system can be made of stainless also.

Stainless steel becomes slightly honey colored from exhaust heat. I like that color but others may not.

It takes a lot of heat to cause that color change. In fact, welding heat causes it. That honey color indicates proper welding temperature. Blue indicates overheating from welding and black is burned metal that isn't even stainless any more.

I weld as an amateur, not a pro.
