Header installation - Need Help!

[blinkwatt]

Hey I think the sellers I.D. was something like "42150" right? Is the header wrap really neccassary? Be sure to let us know how they perform after you fix the leaks!

Yeah, it was something like that. Just keep in mind that this guys has very POOOOOR customer service, at least, in my case anyway. So, if you read a few of the negative feedbacks, you'll quickly learn why.

The header wrap will be extremely important in my case...my AC tube is just sitting right on top and just to the side of my header on the driver's side. Randall pointed this out in his earlier replies that it will help prevent damage to the hose....now I see why. I will get to posting those pictures soon if you'd like.

And yes, I will totally let you know how these headers perform, but without dyno results. Just listening to them a while ago, despite the leaks, I could hear the deep rumbling....it was pretty exciting! I can't wait, but I will have to until I get the wraps. They should be arriving on Monday or Tuesday. I ordered them through one of the local shops here. Apparently, many of the stores in my area do not carry them, so they are on special order.

I have been keeping track of these headers and trying to decide if they are worth it or not. Your input means alot,thanks.

I thought Randall said he zip tied them out of the way? You may want to search for some threads on the header wrap before you install them,it has pros and cons.

The more the better,I may need to do this mod sometime in the near future.

Has the leak/leaks set off any CEL yet?

"I have been keeping track of these headers and trying to decide if they are worth it or not. Your input means alot,thanks."

I would have to respond,.... it depends on what you want the headers for. I honestly wanted them because of the following two things: (1) inexpensive and(2) I wanted to know if I could install them myself. Now, if I end up feeling a slight difference in the ride (more power and a nice sound) without throwing any lights,.... well, I'll be happy. :dance: I haven't seen any CEL lights yet, but then again I don't think I let it run long enough to throw one off. Isn't there a time frame for these lights to go off?

Unless, I quoted him wrong, this (below) was taken from post #15. Maybe I misunderstood him. If you could provide me with some of the pros and cons I would certainly appreciate it. Also, if there's an alternative, then I would appreciate that as well. Thanks in advance.

"Oh yeah, be sure to zip tie off the AC line on the driver's side to move it away from the new header, and then wrap it with high temp foil tape or exhaust wrap to keep it from melting."



"I may need to do this mod sometime in the near future."
In this case, I will try to post more stuff to hopefully help out...although, ...since your car is a more recent model, it may have wonderful little tidbits of its own... I think cats go with your headers, right?

If I remember correctly you should have gained about 15 lbs. of torque and 10 hp at the wheels according the Randall's dyno graphs he did to his car after the modification.

My mistake I thought you were going to thermal wrap the headers,I didn't know you meant the AC lines.

Nope it's a 99' as well.

Well, I'm too pooped to re-write the paragraphs that I wrote to you in response. But in a few words..... I would be happy with modest gains! That's fine with me.

So, in short, it's always good to be a wise and saavy consumer. Do your homework, find out what your needs are, make a decision and stick with it!

dcporsche99: Great to hear you got the headers on, the headers are actually fairly easy to remove on our vehicles. Hondas and Toyotas are much harder, so feel graced that atleast something on our vehicles are easy to get to.


I too am making vidoes of stock exhaust being revved to 3-4k rpm and the headers and exhaust being revved to 3-4k rpm. There is a big difference not only in pull of engine while under load and also the sound.

But as for your comment on using a torque wrench. Never EVER use it to unbolt or as a regular wrench, depending on the torque wrench you have (the most common are the springs sprung inside ones) it messes up the reading of the torque. Also don't drop those tools, their calibrations for torque measurements can be misaligned resulting in you purchasing a new one.

Have fun driving the baby around, im sure you'd be happy with the results.

If I were to do this install again...I would:
(1) Buy a jack (a race jack preferably) that not only carries three tons, but does not feel like it weighs and manuevers as if it weighed three tons,
(2) Take the wheels off when I jack up the car (rear),
(3) Spray the header bolts and studs liberally with PB Blaster for 2-3 days ahead of time,
(4) Have a shorter breaker bar (approx. 14") in length,
(5) Be more patient and calm, especially in the beginning when the adrenaline is pumping...more likely to break or snap the darn bolts and studs off,
(6) Have a creeper (my back and the back of my skull were killing me after this install),
(7) Have a real light, not a freakin' ghetto flashlight (yeah, I have learned),
(8) Take off the plastic support in the middle of the car rather than letting it hang and hit me in the face numerous times before I decided to take it off.....it just had one screw....geez...talk about lazy....,
(9) Make certain that when the ratchet is turning, it's not because the head of the bolt is broken....though funny, please make sure that when you are removing these bolts....take your time and keep a steady hand. For whatever reason, I found these bolts to be sensitive. Not too much brute force. With a breaker bar connected to the end of your ratchet, turn it slowly at first (in the correct direction) until you hear a slightly high-pitched"click"....this was consistent for each bolt when loosened. Different from when the bolt broke, sounded more like a "crap, it broke",
(10) Make certain that when you are dislodging the headers, pull toward the front of the vehicle in an upward fashion and then down at the cat end...be careful as this is where elbows and forearms can easily get scraped,
(11) When installing the headers, especially on the passengers side, the header part facing the front end of the car should go in first, ...don't forget the first bolt to the header here (deep 13mm socket w/ long extension to help bolt go in) and then second either at the other end or somewhere in the middle just to keep it from falling,...tighten two ends first to make sure of appropriate gasket fitment,
(12) When putting on the new bolts with anti-seize, make sure to tighten in the same fashion....take your time and make sure the ratchet isn't bouncing around...this can break the bolt or cause you to have to re-thread the block or have the shop do it (not good),
(13) If no bolts or studs are broken then tighten remaining bolts to appropriate torque wrench setting (double-check this for your vehicle) or if you have broken bolts or studs go to your trusted shop and have them do it after they fix any leaks from broken bolts and/or studs (preferably replace with OEM products)
(14) OR better yet, if the bolts or studs are broken, set a propane torch to it while holding it down with vise grips...be careful as these suckers get ridiculously hotttttttttt...as Ohio said, they will easily come out ....I will practice this one time Ohio, if not on this install, then probably for my new exhaust and cats!!LOL, can't stop laughing!! How's this? Thanks!

etc.... (BTW, thanks to you too MNBoxster - Jim '99 - your initial post was on the lost thread as well. I appreciated your advice then too! I didn't forget!)
