Dual exhaust system 1948 ford with headers

[skidmarks]

I have been away from this kind of work for awhile.
The car is a 1948 ford that is a stock chassis with a mild hopped up 59 AB. Has reds headers.

What is a current price for shops to charge for a complete dual exhaust system installed?

I have gotten estimates all over the place from $500 to $2000 .

Would be 1-3/4 pipe with short glass pack mufflers. Custom bend and welded.
