Thorley Headers
Hey guys- I am thinking about installing a set of Doug Thorley headers #THY-218 on my 2000 EX. Does anyone have any experience with these headers and what do you think of the installation and performance?

I have them on my truck and really like them. I didn't install them but the shop that did said the only problem was the aftermarket exhaust I had on. There are a few threads here on the Thorleys and most are recent. You can do a search to find them.

I have had mine on for about a month now. Really woke the truck up, even compared to the y-pipe mod which helped. The installer did have some trouble. I contacted Thorley and they said they have fixed the problems since I had purchased mine. I don't think you will be disappointed.

Just got a call from him and he said the headers bolted up fine with the exception of the header to the cat. He said the headers are about 2 feet short of connecting with the cat flange. And of course Thorley is closed today. Did anyone with the headers get more than just the 2 sides and the crossover pipe? Or is that all there is? Thats all the picture on the website shows.
