Got two broken off manifold studs currently. Figure I will go with a new header when I do the job so..I have linked a couple questions here and with more questions I will decide which and where to buy. Want to include the Y pipe as my stock set up is a narrow T.

Anyone have an update on the Doug Thorley headers?

Some say they are not being built, or a limit set once enough orders are paid for.?.?

or

Anyone try the Hedman ones?

Although thinner walled they are available now and fit my bill. Just like to know someone tried them.

Thanks for any help.

 

I would see if you could hook up with the group buy going on for the Thorley's. If not then my next choice would be Doug's Headers, then Banks.

 

I might . Summit is listing the part still with a May 4 or 5th delivery. Thing I didnt like about the others was the Hedman instructions say to use the stock studs, so I assume no bolts in kit.? Not sure. Can buy some, but if included with Doug Thorley's then its a point for them.

Anyone know when the group will order and when the pipes are expected? the other post got somewhat off topic from the order and I think the last post was 3-30-10.

 

Hi bakon, sorry for the lack of posts, been out of the states for a couple of weeks. The last time I spoke with my distributor, he said that they can build chrome or ceramic sets. Chrome should be right around $500 or so with the ceramic another $30-40. Feel free to contact him, Steven at 928-273-8114, as I'm sure he'll be able to answer any other questions you may have. I've already got my order in for a ceramic set!

I did not get any pictures. Had two studss broken but when we started working I ended up with 9 broke, 6 came off with the nuts and 5 broke inside the head. Hardest part was getting manifold off. Guy had experience with these and every tool you could buy from Snap on so it went ok. 12 hours yesterday, 5 today. New Hedman Headers fit perfect. Only problem was getting the one O2 sensor hooked back up but even that was not a big deal. Had to pull out the plastic tie down which held it up out of the way on the right side, then it was long enough. O2 ports are down in the collector so it was too short with the clip.

Other observation was I was leaking exhaust out of two cylinders on one side and one on the other. Truck is quieter now when idling, still stock cat back. But does have a jazillion more horse power. I really dont know but it feels better, probably because its done. No noise except a little rumble when full throttle. I can say they did a little something for performance.

The headers came with bolts but we did not use them. Bought the locking ones which was a PITA to put on. Those little clips fell so many times it was a joke. "Hey you drop another one?"

Other than the clips, super looking, great fit, easy to install. No noise. Good gaskets. Mechanic said they were some of the best fitting pipes he ever put on anything.
