Would I be wrong in assuming that the advantage of this header is that it has equal length primary's ?

Thanks in advance

Yes Wink
Many headers are equal length. This is also a step header (tubing gets progressively larger).

The Stage 2 starts at 1.625" (41 mm) OD at the exhaust port, and then increases to 1.875" (48 mm) and finally to 2" (51 mm)...checked again and corrected the numbers.  My digital calliper quit working, so I measured with the ruler calliper, and my readings are approximate.

Not sure what the steps are for the Stage 1 & 3.

ok, CSP has revised the description. sled tins/ heater channel tins cannot be used.

let me try and fabricate something.

I notched my Berg engine support (traction bar) to clear the #3 pipe, but the notch ended up being larger than I anticipated.  I had a piece of simliar bar stock handy and had it welded underneath the notch to add strength.  Hopefully, this will do the job.



The Berg oil hoses are contacting the Wasp pipes, so I'll have to either move the oil filter mount, or add longer oil hoses.

change the oil filter mounting bracket to a different hand.  they do lhd, rhd and top entry.

Good call. Get the one that will point the inlet/outlet towards the front of the car. Cheap solution.

Good suggestion...the "forward-facing port" filter mount should provide enough slack for the hoses to clear the exhaust pipes Smiley

Well, switching to the filter mount with "left ports" did the trick.  The Berg oil lines now clear the exhaust pipes nicely:

To keep this all in one thread, here are a couple of pictures showing how I had to slightly trim the "sled tin" to fit the Wasp J-pipes.  It was certainly less material than I've had to trim for other headers in years gone by, approximately 15 mm.

Another option would be to bend the outer lip of the sleds, and then add industrial tin to close everything in.  I may still install some industrial tin in the future, or make by own.  For now, the sled tin should do it's job of routing warm air out to the rear of the engine.

Here is the right side sled tin:

Is that a custom flange sleeve in image 5?  Does it just slide over the collector and use a clamp to secure it?  I like it!

Hi Neil,

Yes, it is, I never wanted to interfere with the original stainless header.

And, I'm not a welder but my engine builder is, ( I cut up all the bits to the right angles but he expertly brazed it all together for me ) except for stainless, so, I thought, if I can make a transition flange piece in mild steel, then I don't destroy what it came with, but can add anything I like (stinger) in the future... just through the flange section.

So that's what we did, and if I welded a flange onto the end of the exhaust as it sits, then that's all I can have, I may want to change this 10 times (you know how it goes) so it's perfect I think, the only thing I may do as per other Suzuki hayabusa and other exhausts is a pin so if the clamp fails it still won't fall off.

Not convinced it will ever fall off the way it is until I try it, and there is another strap to the bumper bracket I made to hold the body of the yoshimura muffler (which I've repacked in a 3 stage arrangement) and made sure it is 2 1/2" all the way through. If it doesn't look straight through, it is.

I then of course thought, well I don't want to paint this, or keep painting it, so it got plated...

Soon to see how it all works anyway... just need to tune in the new IDA's...

Greg

Can CSP come with numbers as far as decibel loss with that little device?
or was it intended to help with drone/vibrations at a given RPM range..

Apparently this is the street legal design to give max hp, I cannot see how a pipe being bent 180 degrees on its self will out perform a turbo style muffler like posted above. 
Wondering if it will be better to change an existing muffler to fit as Greg has done above, its cheaper and may produce more power.

I believe thatīs because tuned length is more important than a bend.

Yes understand.  But as we know the most efficient exhaust is the stinger - straight through exit.  So is a Turbo style muffler going to be that different in performance than the JSP Muffler?  A question rather than a statement, been waiting a while for these images and trying to justify the extra expense of buying the muffler.  Be interested to see how much the muffler takes from the stinger in HP.

From my own experience Iīm not sure if thatīs knowledge or myth.

On the Wasp prototype stage I tested the muffler vs. the stinger at the track.
Of about 10-15 runs we ended up with 3 stinger runs and 3 muffler runs where the top speed was identical down to 1/100th of a mile.
Same day, car, driver, weather, track conditions, etc. This was at DDD #11 in 2013.

The difference to the production muffler from mine is that we used an off the shelf muffler for the prototype, but the production one is made for the Wasp from Scratch.
I have not heard the noise level of the production, but the prototype was extremely loud. If all goes well I will do some back to back testing on the production model at SCC this year.

To give an idea how important tuned length is, we tested two Wasp stinger versions on the dyno. One calculated from 3rd order pulse and one 2nd order. Same in and outlet diameter.
We lost 7hp with the shorter 3rd order stinger. That obviously had to be wrong, so we changed back and forth two or three times. 7hp difference every time.  Wink

7HP.
About 3%.
That sounds about right.  Wink
