I'd like to take out my stock exhaust manifolds and replace them with some nice headers. I have a Stock 5.0 TPI motor and have a cat for emissions, so the Headers that I need will have to have air tubes for the cat.
What brand makes a Good Header with the air tubes to keep it stock for emissions?

Hooker 2055's.

Dyno Dons Headers

Good call. I'd forgotten Don offers air.

on this latest 92 rs i built i used an airpump eliminater pully and used a set of flowtec hedders that are coated they came with a y pipe that my exsust man had to make fit but they are great then we used in aftermarket cat and i passed emmisiton with flying colors thanks to t custom chip by harris performance

Does Don have a CARB number for his headers? Can't run in California without one I believe...

Dyno don is the best I hear. I will soon see

I will see also. He is making me a pair right now. i can't wait for them to be finished and installed

Yea he's making me a set now also.

2055s

It's been done. Tell them they are SLP headers. Everyone has passed smog with them.

Ok cool thanks guys. How do I contact Dyno Don, and how much do they usually cost? Are you having them painted or coated at all?

I have the Borla Cat-back exhaust on there now, so I dont know if I have to change the Y-pipe or those Headers will fit the Y-pipe thats on there.

Shoot him a pm or you can order them off of top down solutions.com i ordered the non emission headers and they will be coated.

Cost with Y, and no air $833 shipped. Ys are not coated

Ya same here. Ceramic coated, I would shoot I'm a message and have him quote you. They aren't cheap but if you do the comparisons and research they look to be one of the best.

Three is company, he's making a set for me right now too. MO is in the mail Don!

Hey Don, dose Top Down have any of your headers IN stock?

Email TDS. And find out. Don makes them only when needed

No, they are all made to order.

dang. How long does it "usually" take to get them made and out.

3-4 weeks turn around time.

Dyno Dons by far...I just recently recieved a set and headers are a work of art worth every penny...I will be installing soon and will keep you posted on fit...Thanks Don

I ordered a set from Don for a crate motor swap! I am very PLEASED!!!! They look great and fit like a glove! Able to install both sides from the TOP with the plugs out, on my car. Would recommend to anyone, THANKS Don!

Will these Don's headers work with ANGLE plug heads?

When you order them he will ask you what heads you have. I think he tweaks a tube here or there, but he can make them fit straight, angle plug, and L98 angle plug.

They will fit all angle plug heads.
