My question is :

What is exactly what you guys want ?
1 Complet headers with mufflers (covered by the original chrome)
2 mufflers only (covered by the original chrome)
3 a complet different exhaust other than the original look
4 Would you cut your own exhaust and do the install yourself
5 would you send me part of your exhaust if I told you where to cut it before shipping
6 would you pay a $1300.00 core charge on the exhaust plus the cost of fabrication and when we receive your old exhaust you get reimburse.

Please guys let me know what you want

Here are my opinions on a new exhaust, hope it helps in planning this.

1. Most importantly, the look of the original has to be retained. Honda got this right.

2. I've gutted the stock exhaust and like the results. I still think the sound could be deeper. That is more important than loud, although the stock is just way too quiet. If you can create something that is louder than stock and much deeper sounding then you have a winner.

3. I would remove the old exhaust and re-install the new one myself. I have no problem with paying a core charge, but not if I send you my exhaust and my money and then wait 6 weeks. I think you need to plan a quick turn around time.

4. Finally, I would like to see some dyno or other numbers with the new exhaust. Honda is very, very high tech. I'm sure they've spent a lot of time optimizing the stock exhaust. I hesitated for quite awhile to modify the stock exhaust because I was worried about how it would affect performance. Clearly a 900lb Rune isn't made for racing, but if a new exhaust could also provide even a slight power increase then I would be more anxious to have one.

While my opinions may be different than others, I hope they help you get this started.

Dyno a K&N air filter modified Rune (I dont care what the original did anymore because I love the air mod)

Then Dyno it with the exhaust mod added.

If you get any improvement at all, I will pay whatever it costs.
I can do the work myself... unless you dont mind me riding out to AZ this September to hang around & watch!
Total Est. Time: 31 hours, 52 minutes Total Est. Distance: 1976.78 miles (I'm still decompressing from being in Iraq and want to do a long ride before winter)

Keep the original Rune exhaust chrome look & formfactor.
If you are replacing pipes and headers, can you do it in stainless steel rather than rusty iron or steel? I know that costs more, but no internal rusting please if I am paying for an upgrade :D

I like the core charge idea, so that I dont have my cruiser-rocket in non operational status for long. (I put 500 miles commuting / week on my Rune)

I will require cable in my room.

Danny, this is most welcome news.

Following is a draft of a letter I’m preparing.


Dear Clients:

I quit!

I’m retiring to Arizona.

Keep the orignal chrome . I also think Honda got it right. On one of the other concept bikes that preceeded the Rune they had three large oval ports comming out of that muffler. The deeper the sound the better I am not interested in the dyno numbers I would cut my pipes to accept a new muffler. As far as sound goes my wifes valk with Two Bros 6into 6 are the best sounding pipes I have heard on a valk.

Dan,
Chuck is planning on retireing in Az. But he is not going to buy a place he is going to use one of your spare bedrooms. He is taking you up on your open invitation :)

Thanks

I guess I don't have a voice because don't have a bike yet, but FWIW, I also like the stock look but hate the V-twin sound. And yes, after hearing Ken's sound file, Honda unfortunately succeeded in their quest (IMO). I'd like something maybe slightly louder, if at all. I'm over the 'loud pipes save lives' crap :lol: .

I'd like a proper 6-into-2 like the wing, not the one-cylinder-to-the-other-side contraption honda did. A simple cross-over pipe between collectors (after the 3 pipes from each side are joined). Is it possible? Thx.

well i DO HAVE A RUNE....two of them in fact, so i do get to vote 8) ...maybe even twice???

anyway, all joking aside. I would like to KEEP the original look of the pipes. Honda got that right. it looks perfect...it just needs to sound perfect. While the sound is good (and for the life of me, as the owner of TWO Runes...and a Valk, i don't know what all this foolish talk is about sounding like a VTwin? Cause it doesn't sound ANYTHING at all like a VTwin. PERIOD. I've had several VTwins lately....and several 6 cylinder bikes. This sounds like all my other multi cylinder bikes ....of course!)....Honda did not get the VOLUME of sound right. That's what we need improvement on.

Keep the same look, make it slightly louder...and deeper...and throatier. Kind of like going to a glass pack on a Valk, if you will.

I would prefer to meet a vendor at one of the many rallies i go to...and have him do the mod/change out while at the rally. i hear removing the pipes is a pain. that's a pain i don't want to mess with...if i can avoid it. I MIGHT be reluctantly willing to perhaps pay for cores....swap out...then be reimbursed. but that's a lot of bucks. It would have to be done QUICK...VERY QUICK. And that is not my preferred way to go....

i would be willing to cut on my own pipes to do an EASY mod that could gain some sound. as long as it was something EASY. No removal of pipes...no 'rocket science'. SOmething like the old mod on the Valks...just pop a big drill bit in...drill out the rear baffles...and in seconds, more sound. something like that.

Keep the stock look, improve the sound...the deeper the better. My 6-6 valk pipes were the best sounding so far. I'm installing the k&n filter as we speak and am hoping to hear a noticeable difference in the sound. If you can come up with a good mod that keeps the current look with a much deeper sound...I'M IN!!

am i the only one?

I would like to see a different exhaust look. Something more radical. I know there arent many of these around but having one that is even more of yourown is nice. I always imagined the three piped intertwining into one as opposed to being so linear. ofcourse sound and performance would be an issue as well.

I always thought that the six individual pipes of the other prototype would be ultra cool, reminds me of my first look at a Honda road race machine, Seattle's worlds fair. Now that was a long time ago and multi cylinder bike have given me wood ever since :D

1-Yes-I don't think I would like to cut my original exhaust it would be hard to replace if need be.
2-No-it would require cutting the original exhaust (am I right) :?:
3-No- I think Honda did it right wouldn't change a thing :!:
4-no
5-no
6-no

I would feel comfortable swapping out the system.
I would like to have a deeper sounding a little louder muffler with the same exhaust pipe configuration :twisted:

New Exhaust

I want my nasty Black Rune to sound like my 98 Valkrye with cobra pipes.....Id love to leave the stock look but would be willing for ideas. I just hate the look of those three huge pipes that stick way up in the back. Has anyone solved this mistery? Im tired of my Rune sounding like a vaccum cleaner

If you change the exhaust system, save the original. In 10 years, factory exhaust will be worth as much as the rest of the bike, e.g., CBX.

  1. HPC coat over stainless steel, all mandrel bent, from heads to tails, inside and out
  2. Fully welded construction--stainless steel welds, HPC covering everything, including the welds
  3. Equal length headers of the full cross-sectional area / size of the exhaust ports in the heads . . . perhaps even big enough for ported and polished heads
  4. Test / tune configuration for max power: Multi-Y configuration? 6 into 6? 6 into 2? Go with the most power and torque gains as measured by area under the RPM curve, through the full power band.
  5. Equal cross-sectional area per cylinder through-out (e.g. 2 pipes combine into 1 pipe of twice the square area / sqrt(2) larger diameter if round pipe). Yes, nice size pipes by the time you get to the collector(s) and get aft.
  6. Low back-pressure "turbo muffler" type construction with high flow, very muffled at higher frequencies, leaving only a low, mean subtle, rumble--no raspy/licking/popping/high frequency junk like a dragster. Sound reference: a set of dual Hooker Super Competition Turbo Mufflers on an FE block Ford was one of the sweetest sounding truck exhausts I every heard--nothing but low, mean rumble, quiet at idle, and loud, but only at low frequencies when you opened up the throttle. I could burp the throttle in a parking garage and set off car alarms just from the exhaust rumble.
  7. All tucked away under the stock cosmetics as much as possible. You can change the black part of the outlet, but don't change the chrome piece at all.
  8. Built to last a lifetime.
