Weapon R Shorty Header INTEREST Thread

I could care less what it's called as long as it works and doesn't crack.

no, that movie was junk, you are correct, and if you asked me 5 years ago to put anything weapon-r on my car or sell something weapon-r i might also have thought twice about it, but some companies do progress and they work with other shops and have smart and hard working employees and do make good products that work well.

i try not to look at brand names on everything because i have seen it from both ends after selling so many products, you wouldnt believe how many big name companies and small name companies use the same manufacturers. Another way i have seen it is when a big brand name produces something that is just basically junk, so why not be open minded and consider a "lesser known" company to be capable of making something good.

Bringing up this dead thread -- I'm looking for a cheap header and found this full length header Weapon R. I figure it's gotta be better than my stock header, but don't know. Anyone try these headers on a Exige S?

This is something that I'll swap for track events and then go back to street setup (aka stock shorty header and cat). Read it doesn't need to have long term street durability.

I have an EFi so I'll tune for the header.

Looking for input -- prefered input with forced induction application.

Thanks, Rob.

I'd ask Boosted2.0 if the stock header after he ports it wouldn't do just as well. That would be cheaper and wouldn't require changing the header for street and track. The preferred header for supercharged applications is 4-1 with much larger tubing, like the 2bular header.

Ya know, I've thought about porting the stock short header - goes a long way in passing "Visual" inspections. There is a ton of material in the stock shorty -- keeping the heat shield is a plus too.

i have sold a lot of those headers, they have made good power on all the NA cars but i cannot say how well they did on any supercharged car's since i didnt dyno any of those myself and didnt get anyone that posted any dyno sheets on here either.

[ZJChaser]

it ok. I'm running one now. expect to modify the u-bend to make it fit though.

[robains]

thanks for the scoop, appreciate the input.

Both Jim and I purchased this as well... Candidly, the fitment is simply poor. The flanges are nice, the welds are nice, but the U-Bend is simply wrong. It's the wrong radius bend by about 1 inch and it's clocked incorrectly. That wasn't a big deal for us as we simply cut off the u bend and welded new u bends in place... Another option is to cut 1" out of the "apex" of the u-bend and weld it back together... Problem with that is/was (we both did that first) the angle of the U-bend is then off... Which lead us to just starting over with a tighter bend (purchased from Summit) and simply clocking the new bend correctly at the header and TIG welded back on... It was truly 'not' a lot of work if you have the right tools... If not, you're looking at spending some bux at an exhaust shop for it to be "right"....

Best,

Phil

Edit: While I did dyno it before and after, I made other changes to the car in the mix so I can't really say what it did for power... Car currently makes decent power, but I can't say if it's -due to- or -inspite of- the header...

I got 18 HP from my WeaponR header with my BWR SC / EFI. Without touching the tune. (like I would know what to touch)

Same dyno, etc etc. Could be I had a header tune before I had a header.

I would install one based on looks alone. Those tiny tubes on the stock exhaust are a joke. Not to mention the weight savings. Not to mention the extra space I have in the engine bay. Not to mention the heat reduction (just a guess).

[robains]

Thanks all, think I can get the U bend dealt with. At $500, these seem like a low dollar risk ... 18 HP wow!

Got the summit part#? You had to modify the header itself?

Forgive a stupid question, but the part is being sold as a part for Lotus Elise/Exige? It seems strange that it just wouldn't fit by over an inch? Given the price I'm not complaining but what was used for prototype?

[dustylax]

I talked to the person who prototyped them a few months ago about the issue, most of them werent as bad as a couple i have heard about, most of them were very slightly off, Phil migth have gotten the worst of the worst since his was clocked wrong too. Normaly the issue was that the 180 degree U bend wasnt really a full 180 more like 175 degree's so it wasnt perfectly straight into the exhaust. I installed a couple that were fine, another was about 1/4 inch off and just by adjusting the stock exhaust it fit alright w/some muscle grease.

Like Jim said, the benefits are pretty good for what your paying for it, the weight savings is great as well as the easy power gain. You have to be sure that you also have the weapon-r 02 conditioner since that is the only one that i have seen work to prevent a CEL. I'll shoot you a PM with more info.

The fix is pretty quick and easy. No need to order anything from Summit.

I think I have pictures.

It may fit with no modification. It will depend on how mush wiggle you have. Diameter and type of muffler.

I wouldn't hesitate on ordering it. Simple fix, very good flange and welds.
I have installed more than one.

[robains]

Jim, thanks, you have all the answers!

Dustin, yeah price is great, you have PM.

[turbophil]

Ya, Mine was clocked wrong--'er could have been clocked better. How's that

If you simply wrap the apex of the bend with masking tape as a guide and cut that 1" section or so out and weld the two halves back together, it will come together just fine...

Jim- Yours is still that way or did you end up starting over with a new bend? I can't remember where you ended up????

I first modified the bend with a rose-bud and then did the cut it and weld trick after finding I couldn't bend it enough--- and then finally just said the heck with it and welded a new U bend in... In any case, Jim is right. It's not hard to do by any means, particularly if you have the tools to do it...

Probably the prettiest header out there

Best,

Phil

[jim-clayton]

I did the 1" slice. Used an upright belt sander to touch up the angle I wanted. Tack weld everthing in place and your set.

I have the u-bend setting in my office. 3" dia.

[robains]

Sweet, I'll get that car lift install in my garage tomorrow hehe

Ordered - thx Dustin.

P.S. ... Oh, and the upright belt sander
P.S.S. ... and the welding equipment

I think you folks over estimate my "ghetto" garage
