American Racing Headers, Fitment and Thoughts

[jacketedlobster]

Miss the old forums... And the extensive thread on this topic.

Any first hand experience with them? Yes, they are probably ruthless to install, but worth the trouble? Just looking for more info than "ARH Sucks"

If they’re good enough for a low revs high torque pickup truck engine, how could the exact same design not be good for the s54?

[Obioban]

Why provide the ecu with all the o2 information it wants when you could just give it half?

[Obioban]

Don’t forgot to mod your intake (not manifold) for the full claimed gains, because everyone (especially ARH) knows the factory intake is a huge restriction point.

its obvious you dont like ARH, but that makes zero sense

That’s the point...

That makes even less sense.

It was sarcasm. As in, of course they're crap. They took the IDENTICAL design that they use for their pickup truck headers, fitted it for S54 exhaust ports, and called it good. Since different header designs are needed for different powerbands (torque vs revs), they were never going to be a good option.

That was then compounded by not working with the ECU (1 pre cat 02 while the ECU wants 2), and statements from the company that showed how little they understood/cared about the platform (intake comments), and you end up with a product that... never had a chance.

Didn't Hassan just tune a car with these? Maybe he will chime in with another opinion.

[Slideways]

To my knowledge, BMW never used a 6 to 1 header on any of their NA straight 6 engines. Zee Germans must know a thing or two about developing an exhaust system

[Dash1]

I wouldn’t call them crap. Paul Claude stated they (ARH) only came behind SSV1’s by a couple whp when he tuned cars with them installed.

I will post my dyno numbers once my new car is finished. I
I can't believe how much hate there is with ARH.
ARH doesn't suck. There are cars including race cars with ARH headers make more power than other setup. SS V1 was designed a long time ago. ARH came out recently.
There are a lot of information that's not posted here; such as dyno results with ARH vs SS V1. The shop and tuner that I use has done many cars.
Give me a few more days.

There has never been an apples to apples comparison of the ARH headers properly tuned compared the SS V1. Historically, there was a lot of caveats associated with people's claims to their dyno results.

Your data will be welcome, but be ready for people to throw spears if you don't have all the info to back up your results.
