Anybody used Doug's Longtubes p/n D3321? These look similar to the Hooker Super Comps, but the flange is thicker, and they are a buch cheaper. Also, it says they work with angled plug heads, can anybody confirm that? Will they clear a t-56? Thanks for the heads up.
I have a set that should be going on my car soon. I've had some experience with third gen headers but lots with 4th gen headers and I have to say that these are the nicest I have seen. The coating on them is fantastic compared to anything I have seen. No clue on fitment yet since they aren't in.
One thing I am doing is cutting the 3 bolt flanges off and welding some OBX Racing v band flanges on instead. I cannot stand any of the 3 bolt flanges on any headers. Plus it will make installing and removing the y-pipe MUCH easier.
If you are ordering them, I would suggest getting the flowmaster merge as well. Will make building a y-pipe MUCH easier and will be the best option IMO.
i have them, they have awesome clearence, dont get a spohn x member, my set up is L/Ts, T56, spohn x member, and i have like 3 inches of ground clearnce

I have a set, they do not work well with Edelbrock ETec 200 heads plug locations, and on my low GTA with 45-series tires, I've bashed the bottoms of the collectors pretty badly, but as I said, this car is low.
I think the problem is that there are about 6 different locations and angles of plugs between the angle plug heads and the Vortec-style (like mine). I had problems with plug boots burning on my Hooker shorties as well, so it's not the fault of the headers.
But yes, excellent quality and thickness of tubes/flanges, and the same person who designed these headers for Hooker now works for Dougs, so you can be pretty much assured they are quite similar in everything but price.
I have a set on mine with brodix angle plug heads and have plenty of clearance, but you will have to follow in L/T install in the sticky because you wil have to clearance the A-Arms and possibly the a-arm mount on the passengers side. On the driver's side, minor clearancing if any if needed.

Did The plug boots actually Hit the headers on Your E-tec200 heads? i do have heads like that and need some larger headers for my procharged engine, so the D3321 looks perfect..
I'm running a set of Dougs's on a set of AFR angle plug heads. Car is lowered an inch. Ground clearance is minimal, around 2.5-3 inches at the lowest point. Also running 3 inch from the collectors to an x-pipe to 2 magnaflow mufflers dumping by the axle. Will try to get some pice up. BTW the car sounds awesome with the 3 inch x-pipe and magnaflows! BTW, T-56 with Skulte x-member.
For the people that own these, are the reducers they come with 2.5" or 3"? I'm ordering these headers tomorrow and didnt know if I needed to order reducers or not since I'm running 2.5" exhaust.
If you ran a pipe straight back off of the headers, it would hit the spohn crossmember because of how far the crossmember hangs down. You would need a pipe with an S-shaped bend to drop the exhaust pipe down to clear that crossmember, and then its even worse for ground clearance..

I wanna order a set of these and i wanna know this question as well. What size reducers come with these??
I just installed these headers. They fit very nice !!! Angle lug heads work but you need to use a short plug. I ended up using Accels, because the tip unscrews. Which made it easier to install. The colloctors that are give are 2 1/2 outlet. They also give you nice gaskets for the head and collector flanges, and all the bolts, too !!
The only clearance issue I had was on the passenger side rear control arm mount. Other than that, I am very happy with them !!
