  • Complete bolt-on kit with headers and catted connection pipes included

Quantity

Sold as a kit.

I ordered a part for my RV furnace. You shipped it out in a reasonable time, but the part was delayed by the USPS and I received it almost a week after I ordered it. Since it was delayed & I could not wait for it, I got the same part from another place. After I received your part late, I called and requested a return. I was very satisfied with the return process & received notice yesterday that a refund had been issued. All in all, I was very satisfied with your service, but not with USPS.

Great prices

Hopefully these will be correct and I will have them in a few days.

Great products and prices!
