I have been searching the archives trying to find some good information to help me with making a decision on whether or not to go with LT headers, and if so which brand.

My car is a '97 Cobra with Steeda pullies & timing adjuster, off-road Dr. Gas X-pipe, and a UPR Powerpipe / Bigmouth filter.

The car makes it to one or two test and tune days a year, but is primarily used for autocrossing. For this reason, I would really like to help the midrange power and I am hoping the LT headers will be a step in the right direction.

At the moment I have been leaning towards the Hooker headers due to how well the tuck up underneath the car (my current ground clearance with the Dr. Gas pipe is terrible), and their claim that the transmission can be removed with the headers on the car. Lately I have seen some talk about Kooks headers (sold through JDM), but I am having a terrible time finding any solid information about them. From what I understand it should be significantly easier to install the Kooks than the Hookers, but I don't know about ground clearance and transmission accessibility.

Does anyone have dyno sheets for either of these headers on a '96-'98 Cobra? Is there any chance someone has pictures of the Kooks headers installed on their vehicle? Finally, are either of these options going to give me any improvement over my current setup with the Dr. Gas. off-road pipe? I know that shorty headers on the '96-'98 cars have not proven to yield much improvement. Thanks in advance for the help!

Hi Chris,

EDIT: Sorry.....when I was N/A......

Don't know if you saw any of my previous responses during your search. But I went from an off road x to the long tubes with the off road h and picked up some mid range power (between 8-10 rwhp / 10-12 rwtq from 2500-4500 rpms). My peak numbers only increased by 2 rwtq / 1 rwtq.

I don't know much about the Hooker product or design. Hope this info helps.

Good luck,
Brian

William,
Thanks for the info. Guess I need to get on the phone with JDM and see if they can get me any information. I really don't want to be the guinea pig for these headers!

Brian,
That is exactly the kind of info I am looking for. I searched for posts you responded to and did not have any luck. Would you happen to have any dyno sheets you could share?

If anyone else has any other information they could share, it would be greatly appreciated. Thanks again!

Chris

If you do a search for my username you should come up with several "LT Header threads."

In short, I picked up 32rwhp/21rwtq peak numbers from adding: N/A powerpipe/CAI, Pulleys and BBK LT's. My mid range improved quite a bit as well. I would buy the BBK's again, but I would rather have the Hookers because, in theory, you can pull the tranny without removing the passenger side header.

Chris, I'll have to see if I can dig them up (and have them scanned). Otherwise, I think I have some before and after numbers plotted manually.

Patrick has a good point. That's a pretty attractive selling feature for the Hookers. I think I am already facing this issue as I believe some of my synchros are on their way out :(

Good luck,
Brian
