'03 Yoshimura 4-1 stainless full exhaust-$250

[Warp11XX]

Full 4 into 1 stainless exhaust with RS-3 canister. Good condition with 1 missing canister rivet and one small scratch. Pics can happen if interested. $250 plus shipping from 24134.

 

I ran this system for about 35K miles and switched to a Micron setup. Great power, very nice sound. May have PC-3 custom Dyno map, but not sure I can find the CD or recover it from a crashed drive....maybe....

 

Not online frequently these days, so email to hondasixpak@yahoo.com will get the quickest response.

 

Thanks, T

Bump...last call...🙃

My kid has a stock set, he might consider it. I'll ask him 

[superhawk996]

I was quite surprised with the power gain of this system over stock.  I expected a slight shift in the power curve, loosing a bit down low and gaining a little up top, but didn't expect it to be very noticeable.  If it lost any at the low end it was minimal, the gain was impressive, and I didn't tune for it.  And it's way lighter.  As much as I like performance, I prefer the look and sound of dual so I sold the Yosh with my first '97.

I wonder if this is the F.I. header which is said to have more low end with the top end of the single can would it be the best of both worlds on a 97-98?

I don't quite understand what you're asking, but I'll try to answer anyway.  The Yosh has no cylinder pairing like the stock headers do, it's 4 pipes into one all together.  The stock ones pair the 4 cylinders down to 2 pipes, then those pair into one.  It's a 4 into 2 into 1, instead of the Yosh's 4 into one.  The stock is actually 4 into 2 into 1 into 2, but the last separation means nothing as far as the merging effects are concerned.  It could stay 1 at the end or split into any number of pipes without directly changing what happened at the final merge.

 

Pairing theoretically adds more midrange than a 4 into 1, and how the cylinders are paired also changes that curve, as observed in early vs late model pairing.  I'm pretty sure the Yosh has larger diameter primaries which also theoretically reduces low end power.  The total design of a header can break the rules/theories that are generally applied to headers.

 

My recollection of my butt dyno test was that the Yosh lost a bit of power below 4k, about equal from 4-6K then the Yosh increasingly ran away.

 

See also- tri Y headers for V-8s.  They pair somewhat like the stock Bird headers do and sellers claim a torque gain.  Most tri Y's are short tube which are rarely much better than an iron manifold no matter how the tubes are merged.

 

I also have an aftermarket Bird header I took off of Cecome's bike, now my bike, that is fucking garbage.  Its only redeeming qualities are that it's lighter than stock and a 100% effective anti-wheelie device.  He brought me his bike to diagnose/fix his low power problem, as soon as I saw the header I was pretty sure it was the problem.  I put on a stocker I had with his Two Bros cans and it came alive.

This pretty much answers the question.  I know about the stock headers and was thinking the Yosh header was paired like the F.I. header.  It has been many years since I messed with all that stuff and the info fades away.  Too much brake clean?  😉

Or not enough.  Take another hit and report back tomorrow.

Our loss, Tom.

 

 

[Warp11XX]

Not a total loss...😀 Must just find the time ...😆 

[Warp11XX]

Heads up on email address charliemarks1704@gmail.com

 

He is a scammer that strung me along for over a dozen emails and then tried to get me to make changes to my PP to "receive" his payment. Dirty bastard he is!! 

 

Carry on....😐

[Warp11XX]

Sooo....thanks to charliethepenismarks1704, I now have pics and the RS-3 system is boxed and ready to travel....wherever it may be called upon to go...

 

I replaced the missing rivet with one having a slightly smaller head...pretty unnoticeable....

nice repair. I sent the pics to No. 2 son.

I think that is a great deal. Wish I needed one.  @blackhawkxx  I don't remember the header differance between the carb/FI either.  Maybe someone will explain in this thread?    Rich, don't tell them we know the 98's are the fastest model. It's true. The Black ones.

97-98 pair 1-2 and 3-4 from left to right.  99-up pair 1-4 and 2-3.

And one style will fit on the other bike, but not the other way around without modding.  I can't remember if it's early header onto late bike or vise versa.  I'm pretty sure the Yosh, maybe all aftermarket headers, fit all years.

 

And '97 is the fastest.

The 97 is Black so that helps.😄
