4x4 what headers, I have the money now so I want to know if Doug Thorley Tri-Y are any good, if not why? Any other suggestions, anything will help, I'm running JBA shorties and was told to get rid of them. Help.

 

get rid of the shorties. I have the ceramic coated Doug Thorley tri-y's and I like them. they mounted perfectly and were of good gauge. none of that thin crap.

 

I know ASM"S will fit on 4x4's. And they make great #'s, I have had no problems with mine. I'm not sure if Thorley's will fit a 4x4.

 

I'm blind, I didn't read that part.

Call them up and ask them. 951.739.5900

 

I don't know about Throrley's, but I really like my ASM's. The headers look great, fit great, and feel great. The install took me no time at all, I had my y-pipe fitted at a local shop. He said that they were the best looking headers he has seen in a while.

 

The Thorleys are great headers. I've had the Ceramic 310-Y headers on my 6.0 L for two years now. Call Randy Miller at Thorley 951-739-5900, he's a good guy.

You can look on my web page and see what they look like before and after installation.

They are not 1-3/4,or are they?

 

The primaries are 1 5/8" as I recall.

Yep 1 5/8 primaries,and 3/8 flanges.They do fit 4x4's. Took less than 2 hours to install including the welding.I love mine.
