Thirdgen Header option chart - explained
I made up a chart of <B>SHORTY</B> headers for Thirdgen's. These should help people and save on a little research time when trying to figure out the "best" headers. There is no opinions in numbers, so when someone tells you that there "such a so" header is better than another header you can compare them for real. I've tripple verrified the info in this chart.

<PRE>
Header Gauge Flange PRI OD PRI ID COL OD Col ID Pipe OD Pipe ID CAT OD CAT ID
Hooker 2055* 18 0.31 1.63 1.53 3.00 2.20 2.50 2.40 3.00 2.90
Hooker 2460 16 0.31 1.63 1.51 3.00 2.80 n/a n/a n/a n/a
Hedman 68470* 18 0.25 1.63 1.53 3.00 2.80 2.25 2.15 2.50 2.40
Flowtech 16102FLT* 18 0.25 1.50 1.40 2.50 2.30 2.25 2.15 2.50 2.40
SLP 3004* 17 0.38 1.63 1.52 3.00 2.20 2.25 2.15 3.00 2.89
SLP 30005* 17 0.38 1.75 1.64 3.00 2.20 2.25 2.15 3.00 2.89
</PRE>
<HR>

(And now for the opinions)

<B>Hooker 2055.</B> Prolly one of the best headers available. 50-state legal. The best part of this header is the y-pipe. 2.5 " mandrel bent, into a 3" pipe. Primaries are large 1 5/8 18g. Problems: collector gets down really small. It could be modified to flow more however. Avg price: </B>$365.00 for the set</B>

<B>Hooker 2460.</B> Initially appears to be a good header. It's more
durable than a 2055 header (and heavier), however the thicker gauge primary (16g) is more restrictive. The collector is larger than the 2055, but by the time the exhaust gases reach the collector they have prolly slowed down anyway. No Y-pipe is available for the 2460, but you can fabricate one out of some mandrel bends - budget about 150.00 and a long weekend. Avg price: <B>$150.00 for the headers. </B>

<B>Hedman 68470.</B> Decent headers. Not as durable as hooker, but very lightweight! I got mine ceramic coated by ACS.

Heres the deal. The <B>OLD</B> style Has large 3" collectors with 3 bolt flange, large 1 5/8 18g primaries, and a y-pipe is available.

The new style uses a ball and socket flange like a Hooker 2055.

The y-pipe is a 2.25" pipe that y's off into a 2.5". However, you can cut this at the y and use 2 mandrel bent 3" peices. The collector design on the pipe (for the y) expands out to about 3.25" which allows you to easily weld the 3" section in. <B>Y-PIPE WONT FIT WITH MINISTARTER!!</B> Also, you'll need to weld an o2 bung on the header collector. Avg price: <B>$135.00, Ypipe #17470: $95.00. ($215 set) </B>

<B>Flowtech 16102.</B> I personally used these headers, and they are
junk! The flanges are machined VERY poorly, the collectors are 2.5", tubes are 1.50" OD, and the y-pipe is designed like the stock, so you can't just cut off the 2.50" section and replace it with 3" mandrel bends. The headers are VERY heavy, and so is the y-pipe, but this doesnt appear to help any with heat retention. Avg price: <B>$200.00 for the set.</B>

<B>SLP.</B> SLP makes the largest tube header you can buy in a shorty for a Thirdgen. The OEM style collectors are better than the the Hooker 2055's, and are 2.5" The headers are made out of 17 gauge stainless steel, so the 1 5/8 version actually has SMALLER tubes (ID) than Hooker 2055, hedman 68470 headers. The Y-Pipe won't connect directly to your cat, you will need a 45* angle. The y-pipe
is actually a nice design, and is 2.25" tubes into a y-collector. The tubes actually bend 90* back, so the y-collector faces the back of the car. This is a unique design.

I just switched from hedman to SLP 1 3/4, So I've now tried 3 of the most popular headers for thirdgens.

Slp no longer sells non ceramic coated versions. So the 1 5/8 headers are $649, and the 1 3/4 are $699. Add the 45* adaper at $35. Avg price: <B>$684 to $734 for the set.</B>

Edelbrock TES and Dynomax aren't on the list. Some may say that's appropriate, but...

Those who make dual-cat versions are TES, Hedman, & SLP.

Hooker 2460 do not come with A.I.R. pipes, but they can be specified for them with a "0" (zero) prefix.

Hedman emmissions-legal setups are 68481 (single 3" cat) and 68491 (dual cats). Include A.I.R. & O2 fittings, y-pipe. About the same price as TES/Hooker 2055 (dual-cat version is less, for some reason).

Very good thread and I applaud you for going the extra effort to really research the different headers. Your finding are basically what I have found to be true as well and have included in one of the stickies too. The 2055's are awesome! lol

Very nice. And appreciated.

One thing I dislike about it, is it makes me want to be able to get headers even more now. lol

Uh, you might want to edit that post, it takes up like 4 screens....
Other than that, good work! It's nice to see some info put together on the exuast board so users don't have to go looking everywhere. I think so far we have almost eveything covered, now all we need is a review of catback systems... Volunteers anyone?

As i've explained in previous posts, its the ID of the primaries that really matter.. It doesn't exactly make sense to go with SLPS though because of cost..

The table in my last post was found on the 'net. I have not verrified the information.. What i'd like is, people to respond to this with measurements, etc of their setups and I'll edit the first table in the post. Then this should be made into a sticky..

If anyone would like to "review" there headers, I'd like to add that to the first post too.

They will if you have single cat.. Not dual..

17470 for the y-pipe.

Do yourself a favor and call american coating specialties,
281-446-6203 and get the set from them.. Coated 68470's is like $240.00, and the y-pipe 95.00 (which is cheaper than summit).

They will also weld the o2 bung on it, which is required (make sure you remind them).

MAC also has a powder coated short headers for a thirdgen you have to take out the smog pump pipes but overall these are the best headers ive found ... you can really feel the difference and time difference depends on what mods you got ...Just my opinion but I recomend them.. kinda high priced but good..

Money is not a problem. I want the best power, which I see alot of people saying SLP.


I like the idea of no air tubes, just don't want to run into the basic slp header problems and have to dent the header.

Well if you are going by the chart, which I conclude to be true from my research as well, the hooker 2055 y pipe is a much, much better design and will support more power than the slp's will. The hooker's only come in 1 5/8 primaries, but they just happen to be the biggest ID 1 5/8 headers available. If you want to go bigger you will have to get the slp's, but it is kind of pointless seeing as how the y pipe is only 2 1/4 inch compared to the hooker 2 1/2. You will also most likely have to dent the header primary or modify your steering shaft, which is kind of scary to me. I have the 2055's and cut the air tubes off myself and it was pretty easy if I must say so. Besides the huge rip off with the slp's, the hookers are not only cheaper, but are a much better design overall.
