UZJ100: Good work! Has he seen hoser's photo of the limited clearance on the driver's side (steering shaft)? Probably not the only design hurdle but maybe the biggest one.
 
I sent over all pics.
 
Is the idea that the header will bolt to the existing pipes, catt and exhaust? Or will it require a total rework of the exhaust? How about clearance with a Slee belly pan? Assuming it bolts in and takes place of the original exhaust manifold. I'm in.

Just to give credit where credit is due, those were Loud's photos I reposted and his effort to try and have the JBA headers fitted.

I would be in for a set but my 1998 manifolds are still good! Plus, I think I already blew the 100 series budget for this fiscal year ;):D

Ooops...there I go again giving you credit instead of Loud :lol:.


Ok. Playing devils advocate here. Assuming you are not replacing a set of cracked manifolds to begin with (in this scenario I'd much rather pay for headers than OEM manifolds) you'd really need a set of high flow cats with dual exhaust to take advantage of a properly tuned set of headers anyway right?

And then with a less restrictive exhaust system what is the chance you'd lose low end torque in exchange for more power at the top of the RPM range?

And it would be, of course, good to know if DT integrate the O2 sensors ports so that they are in the proper position to reduce or eliminate the potential code issue.
 
Funny how I haven't been to this site in like 5 years and run across this topic!!! I live in the LA area and have a '99 LC. Could I get a discount for using my LC as the loaner? I would love to have a pair of headers but $742 is a bit steep for me with 2 boys and a 2 year old baby girl.
 
The price is 642 if we get 20 folks. I am sure we could take up a collection for the loaner LC. My biggest concern is that we only have 4 out of 20 signed up.

Times must be tough even in cruiser land. I think 4 is the lowest committal I have seen every time this has come up in the past.
 
I'm in as long as DL answers/addresses my above questions satisfactorily.
 
I will double check with DT however I know they sell these for the tundra and would have to work with all o2 sensors. Up to 5, only 15 to go. Come on guys.
 
Nick at DT said the gain should be about the same as the tundra which works out to about a 10% gain. 10% seems a bit high however I hope he is right.

10%.

well. I think your man is being conservative.
As i said in my post : It's like i have a new LC100. I'd say 20%. Depends on your package.

I know it's hard to guage from afar (ie you are in USA and i am in Oz) but as i keep saying, and i really hope you arent sick of hearing this: the difference is night and day. For me anyway.

yes i have a 3" free flowing system. And yes, the Pacemaker extractors i have might not be the best choice....Genies are bigger....we'll see
But i have what i have.

And the detractors....wow. i never thought i;'d get so much flack, not from here tho, from OS forums.
anyway.
despite the fact i am not working and the beast may end up hiding somewhere....it's the best decision i made. (the extractors/headers)

And when i come out of the bs thing we are all going thru, i'll re-register the LC and be back (and legally driving it) and hopefully have pics in whatever i do to it.
take care

Just to point out the maybe not so obvious. The dyno chart posted on the TS site compares the 4.7 with catback exhaust vs the 4.7 with catback AND their headers. Would've been nice to have all stock and headers only dynos as well.

I'd like to know if their headers would be fine with the current borla cat back that I have. I wouldn't want to change the borla cat back. Also would it use the exact same tight space as the stock pipes? Because many of us have some modifications to their engin bay etc. that might interfere with the headers.

Provided that my concerns are addressed along with what spressomon raised in post #26, count me in. :)
 
On a side note I just found a guy that was getting rid of his brand new stainless Boost Brothers headers for the 05-06 Tundra V8 ($140!). Construction looks pretty good, 7/16" thick flanges. I will be looking at this to fit onto the LC engine soon. I will let you guys know what the difference is between the fitment of a Tundra vs. LC. I've been emailing both Gibson and Thorley about the difference but they do not know and could not give me an answer. Stay tuned.....
 
COUNT ME IN.... only if I can be #10 or #20 on the list, if not don't count me in!

Will it be $642 or $742?

Search, it's been tried.

Siglo, get rid of the borla if you ever want to run slee skidplates (I guess you dont need them for rocks, but maybe IEDs incase you run up to Iraq).

I took the JBA bolt in header replacements and attempted fitment on my LX. Lined up with the block, obviously but the point where the tundra mid section lines up with the header is different then the LC....preventing compatibility.
 
Thanks for the input on fitment between Tundra and LC headers.

I thought one of the problems would be hooking up the Tundra headers in the LC to the LC exhaust... My bud has a welder and knows how to fab exhaust manifolds & piping. Once we get this going I will let you guys know how it was done. (He's actually so talented with fabing and welding that he can create a header from scratch if needed!).
 
oh, well while your at it modifying the tundra headers to fit the exhaust, might want to make them not hit the firewall...could help.
