Flowtech are so much cheaper?


Doug Thorley does manufacturing in the US, others don't. That may translate to the quality of welds and the fit. The Thorley product is ceramic coated, Flowtech is painted. Thorley product is 14 gauge, 0.0747 inches thick. Flowtech is 0.049.

Both have 3/8" thick flange of steel. I can't tell if there is a difference in the quality of that steel.

Hedman flange is 1/4". Thickness of tubing is 18-gauge, .0478".

Choices abound!

The question is why are Thorley so expensive?

Depend on what you want. SS,coated,18g,hd 3/8 flange.you can spend well over $1000.00

Replace the gaskets with Remflex gaskets and you will never have to do it again…..

Funny this 88 Barth has headers, Stainless steel and an expansion joint between the center cylinders. They also have ports for the AIR pumps that have been plugged. Pretty sure not stock. So the digital dash was available on this year Regal, I would have never thought!!!

When Benobob came to GTG at Springvalley I had chance to check his coach. It had a electronic dash. He thought it was a Chrysler unit. The coach was 1986. That the only one had seen.
