Default KL Racing 8v NA Header 2017

My quest to purchasing one of these originally started out as a group buy feeler for a KG Trimning Type 2 Header. Ronald (culberro) sold me on KL Racing. Total cost was $288.48 (after shipping). It's essentially the KG Trimning Type 2 Header with the exception that the collector is advertised as 2.5" OD (just a smudge above 63mm). I placed the order on their website on November 18th, and received it December 1st. 13 days isn't bad considering it shipped from Sweden to Phoenix, AZ over Thanksgiving weekend and made it's way through customs!

Packaging

Here's how it came. Didn't appear to have any dings. Right around 3' in length.



It also came with a sticker and a bottle opener. Free swag anyone?



Collector

Measuring the collector:



I like the flow inside the collector:



Size Comparison

Comparing it against the stock header assembly. The secondary and primary tubes are clearly longer:



Weight Comparison

I wanted to compare the weight with the stock header assembly.

Weight of the stock header assembly was roughly 27.7 ibs:



Weight of the KL Racing header was roughly 13.8 ibs. 14 ib reduction isn't bad!



Overall I'm very satisfied with the purchase.

Missing Bell Housing Bracket An Issue?



Has anyone had any issues without the bracket to stabilize the header to the bell housing?

Not needed with the 1 piece header?

Looks good. Nicer than the Folkrace header I installed on a 745.

I made a bracket to support the header. Just a piece of 6-8mm thick steel stock welded across both runners (secondaries) and a threaded hole in the plate. Mating to the original springy-wire style holder. Fits like stock.

Nice weight savings! Might have to pick one of these up for the daily.

I would probably weld on a tab to mount it to the bellhousing, just for peace of mind.

Yea, I think I'm calling BS on the bracket with the new header. I mean, look at all the hooker headers out there for 350 Chevy's. You'd think if headers cracking was an issue then they'd have brackets on them as well, but they don't.

Do yourself a favor and have is ceramic coated . It will add years to the life. Also post thought and gains in performance and mileage. Real interested in one

Is the tubing close to 0.060" / 1.5mm thick?

Yep. Replaced A LOT of header gaskets over the years. It isn't going to break the header, but the additional support would take the stress of the bolts to head- that is welcomed even if a lot lighter. Less movement at the gasket interface. YMMV
If one did not want to weld on the nice, new header, an exhaust clamp could be used with a fabricated bracket.

Curious what mods you've made to the car.

Dang. Well, I think this alone is going to make me weld on a bracket. The exhaust pipe I picked up is fairly heavy. I could see the lack of a bracket causing unneeded pressure on the header bolts.

I don't believe so. A local coating company quoted me around $160 to have it ceramic coated.

Measured with a micrometer, and it was around 1.5mm thick (which is close to 16 gauge).

Yes. I'd really like to have it coated. A local coating company said the lead time was about 2-3 weeks as ceramic coating is a bit of a process.

In addition to improving velocity (due to a reduction in heat loss through the tubing), the engine compartment should stay cooler. In Phoenix AZ that would be huge.

I don't think it is a structural issue per se. It would take a lot to break the bolts and the header for that matter (although weird stuff happens with steel, high heat, and cracking). My recommendation was purely from the annoyance of gasket replacement. There is a reason that bracket is there from the factory.
Look forward to updates.

headers come loose because the gaskets relax in never put a header on anything that didn't need to be tightened up later, everything from cheap to 1000 a pair

Ther is a place in Jonesboro Ga that should be quicker. Do t remember the name but I have spoke with them several times but found some one local to do it cheap on a plus 90. Problem is he stopped doing it. You all got me wanting to order one and my money is funny right now. Going to trim some fat and will see!

very cool, I would like to change out my old stahl 4-1 header for one of these. Assuming any website navigation issues, it was a fairly straightforward process??

How come? Wouldn't the 4-1 design provide better low/mid-range torque?

Yes it was. The only issue I ran into was this: I registered on their site and added my address to my profile. I live in a condo with 4 digit unit numbers. When I was checking out my unit address appeared correctly (i.e. all four digits displayed); however, the email confirmation I received had the 3rd digit missing. I quickly emailed them to inform them, and they responded right away to let me know that they updated the shipping label. Didn't have any issues other than that.

Also, if you're like me and you check tracking information every 5 minutes, customs felt like an eternity! No updates we're posted for almost a week, then one day it was Arrived in Phoenix

You can always paint it with some POR20 and put more coats of paint on later. The inside will get covered with carbon so it will get coated from your engine.

Hmmmmmm no. the 4-2-1 thing is supposed to be all about broader powerband, isn't it? You see in invariably on rally cars and they have to operate from 3000-7000.>

ya know? a 90L just out of the woods and you snap throttle shut and brake like hell and initiate...ebgine revs dropped from 7000 down to say 1400 (idle) so you jump on the gas and it sure as fawk better PULL NOW!.. Your cornering--balance everthing depends on it pulling... 4-2-1


4 into 1 I have seen on roadrace cars....and non-poofter road race car with have a box that close enough the motor drops no more than 1000-1200 rpm on a shift so PEAK POWER is the overarching concern..and what do you see? 4 to 1..

Might have to get one of these for my otherwise stock b230f... would look good in the engine bay and would give me a chance to re-do the rest of the leaky ass exhaust... I'm assuming for an otherwise stock motor there would be basically 0 performance gain with one of these?

Nice. Thanks for measuring and reporting back.
