You are probably right...

Hey, I didn't bring up the SC... and I do think worst scenario on header resale would be even money if not better once the run is over. Headers do not wear like a SC kit... not to mention no missing parts, ETC. Just don't want people to automatically think the end of a run = monetary gains. Most if not all resold SC and Turbo kits here have been at a loss to the original owner.



Still cool that there are headers for our cars.

 

Just to clarify from what I understand from John's posts the MINIMUM order is 20 sets for a run of headers, 20 is not the the maximum that can be ordered... so as long as you get your order in before the first build set closes you should be fine (JB please correct me if I'm wrong).

Morris - I asked JB about having these before Lexfest and he said not to count on it. I was going to see if SRT could do the install while the GS was already up here.

PS, those that put down money a long time ago to make sure these happen should go to the top of the list for delivery cough cough

 

I think I'm going to have to ban you from this thread

EDIT - please do not respond to this post

 

Thanks thats what I needed to know.

 

glad to see this coming together . curious to see dyno on a otherwise stock 430.

wow Morris, you sure would save alot of time, money and aggrivation by installing these with your motor pulled already. sounds worth the wait to me, especially with a boosted motor.

 

Man, this thread is moving FAST!! This is a good indication that the headers are making power, my butt-meter originally thought I lost power with the Y-pipe, but the dyno proved my butt wrong. Actually, the gains were 1hp and 6 tq on the dyno. John and I are still trying to get this together for everyone here on CL, but it might have to wait till next month. I went WAY over my mod budget for the month

 

I very interested to see your gains, Morris. I was thinking of going the FI route later and was very curious in seeing your gains versus someone without JB headers. Please keep us informed.

 

Here are some pics from the install, I'll have some more up tommorow...

JB vs OEM




JB Header in OEM heatshield

 

Great pics!!

Thanks for the JB header in heat shield pic. This is what I was planning to do inorder to disguise the aftermarket headers.

I know these will not come with a legal sticker, so has anyone already discussed the legality of these in Cali?

The question I am asking isnt if I should purchase, rather do I have to hide them in order to smog?

 

It cant help but improve FI especially Turbo I would think. My expectation is that you will see faster spool times and perhaps more HP at lower boost levels.

But I am already over budget and was going to stretch to get the headers if I could get them installed while we put the engine back in. I am not in a position to handle the cost of the headers and install labor right now.

 

Dave, you are correct. Loren needs to run at least 20 sets at a time. Obviously they cannot be built all at once. He will probably run the first 20-30 sets and then additional runs all based on this INITIAL VOLUME of orders. If people do not get their deposits in by next Friday there is no way of knowing how long before another 20 orders are recieved. Example. If a total of 45 orders is recieved, and he runs 20 in the first batch, he will run 25 in the second. If then another order is rec'd it will have to wait for 19 more

Target date on production is 4 weeks from next Friday.

Yes Dave, you are in the 1st run

 

Morris, you are correct. More efficiency all around. Quicker spool, more power at ANY boost level, cooler engine at ANY power level.

 

gawd is really helping here with information, details and pictures. Thanks man

I also want to give credit to Greg aka SRQ400 who was the one who initially pointed me in the direction of S&S Headers... Thanks Greg

Now, looking at the comparision picture of the drivers side you may notice that this is the BETTER of the 2 stock manifolds. It has 2 decent runners and 2 terrible runners. The passenger side has 1 decent runner and 3 terrible ones. REMEMBER, this is the GS400 manifold which is actually better than the GS430 manifolds. The 430 manifolds have 2 ok runners and 6 terrible runners. The 430s should gain more than the 400s.

 

No CARB certification will be sought. All aftermarket parts must have a CARB E.O. # to be "legal". That said ironically these could actually be BETTER for emissions than the stock manifolds. The superior efficiency could bring the cats to operating temps faster creating less cold start emissions. They will certainly pass the tailpipe test. The visual is the only concern. MANY cars in California are heavily modified and "somehow" get through. I would suggest some searching for how that is happening.

The headers have no provision for mounting the heat shields. I really cannot offer a good way to secure the shield in place. Personally I would suggest cutting the shield into a top and bottom half and placing the top half over the header, secured with wire for the test ONLY. This would probably get you past the visual as the view from the top would be normal. Afterwards, remove the partial shield to avoid rattling and rubbing on the coating.

 

Great minds think alike! I have been thinking along these lines for some time, planning for the day when I have to pass inspection. I totally agree that actual emissions will not be hurt at all, but the visual is the concern. A *temporary* heat shield placement should suffice...
There MAY be a market for factory exhaust manifold heat shields here in Cali soon!
