I got really excited today when my arh LT came in..........until I went thru the box, no gaskets???? for the price im really hoping gaskets r included n the price. This is my first set ever, shouldnt they come with it???
A Lot of people reuse the old stockers, I bought a new set of OEM gaskets when I did the ARH's.
If you have the 1 5/8" primaries the stock gaskets are fine. If you have the 1 3/4" then I would highly recomend the Kooks gaskets that JDM sells for about $30.00.
This is from experience!!! The 1 3/4" primary tube laps over the "D" shape on the stock gaskets and will be prone to small exhaust leaks.
I never had an audible exhaust leak, however, when I pulled the headers (which were installed with NEW stock gaskets) there were carbon trails that are evidence of small leaks.
If you hold a stock gasket up to the 1 3/4" primary you will see that the raised sealing surface on the flat side of the "D" shape on the gasket does not make contact with anything on the header.
I am saying that it is better to use the Kooks gaskets which seal perfectly.
If you want to spend your time/money doing a fairly difficult header install and save a buck re using the stock gaskets........ Be my guest!
