Where can I get a "Long Tube" Header for my RX-8?
I know I can purchase a short header from Racing Beat and some other sources.
However, the real ticket with racing is a long tube header. I know some of the teams run them. Are all of you just getting them custom made on an individual basis? I have a Racing Beat Header I could have "extended" but if there is an easy source to purchase a long tube header from I'd prefer to do that.
Let me know!

Due to the exhaust port design on the Renesis you are correct that there is not as much to be gained on this motor with a header as compared to the older rotary motors but there is still power to be gained.

How far are you from Chicago, I have a nice stock '06 that will fit perfectly

Selected. E-mail me at Charles@BlackHaloRacing.com and we can schedule a day of fun. Thank you.
To be clear; this first step is only a fitment test. Once we have established that the unit installs and fits properly, we will set about making a few for dyno and driving tests. This process takes time and we are in the middle of moving from one shop to another right now. How you will be compensated for your help is yet undetermined but I can assure you it will be something notable.

Just shot you an email.

My friend in this area had a custom header back system made. He provided all the measurements of the header design, collector length, and they fabricated it to his specification. I am sure any good local exhaust shop could do one for you if you did a little bit of research for the sizing, that is, if you don't want to purchase a potential legendary BHR product

Dyno testing by various sources (including some experimentation by Racing Beat on their very accurate engine dyno) has shown that a longer tube header provides a performance advantage over a shorter header or stock manifold even on a stock Renesis.

However, what you want is easier to build than you seem to realize. Simply take a Racing Beat etc short header, cut it off before the merge, extend the pipes with slip connectors in any lengths you want to test, with a proper slip merge on the end with spool pieces to account for the various length changes, and have at it on the dyno to figure out what you think works best

I am not sure how effective that exhaust would be on a Renesis. I am going to dis-agree with some of the above, as a "long-tube" header does seem to add power, and the exhuasts that are working on my 8's are likely nothing like what you would expect. I will agree with most however and say that all of the off-the-shelf stuff seems to make about the same power.

Modified a Racing Beat header into a "Long Tube" Header
Ok, so at long last I had about a foot of extra length added to my existing Racing Beat Header and the Racing Beat Midpipe shortened to fit. Some pics are attached.
It wasn't super hard to do (for an experience fabricator) and seems to fit just fine.
Next race is in a couple weeks so I'll report if it seems to help at all.

Let us know how testing goes, I might have to try this.

Well... sure I could throw my street muffler on and drive it around the street before the race just to make sure it's not going to fall off or something. I could put the car on the dyno but as I have no BEFORE dyno numbers it wouldn't really tell me anything. Honestly, I'm not expecting more than a couple horsepower from this mod. But every little bit helps.
By using an off the shelf short header and having it lengthened I THINK I saved a lot of money as full custom headers tend to be very expensive. The fabricator charged me $180 for add the foot of length to the header and shorten the midpipe. Not bad in my opinion considering that is was good qualify work.
