Exhaust System Help

[Steel]

Bet the difference is what we in Australia describe as a 'flysh!t' .. meaning very very very small

That's kind of what I'm thinking too. But I still wish CES hadn't waited until right after I bought my pipe to come out with theirs. I really like the look, and think the heat situation would be better.

To be an exact test you would fit one pipe to a bike, tune it to it's best then fit the other pipe and tune that to its best. Then compare the two graphs. Which type of CES pipe is it? Apparentlythere are three.

It actually wouldn't be too difficult to do that. Can't speak for Carpenter pipes but my CES was such a perfect fit they could be put on in 15 minutes - less if you hurried and didn't stop to admire them a few times.

Not sure how long it took Steel to fit his pipes, but mine were on in VERY short order. We could probably arrange a "shootout", but I'm not sure it's required. Both exhaust systems dramatically increase torque and HP so at the end of the day I think it comes down to aesthetics...we shall see.

Funny.

You're right of course. Tuned, equal length of the CES I'm sure is important for somewhere in the rev range and I understand the Carps do best at the upper end. But with otherwise stock motors I doubt there'd be much difference.

Not sure of the significance of the little vid Phil? A valid test is try them as described above. Each pipe tuned to the same bike. I am tipping Bobs pipe more above 4500 and CES ( if it is the one I thnk) better under 4000. Stock engine?

It simply means that this is and will be very interesting... no hidden meaning.

Interesting reading for those wanting to more about primary diameter vs length vs power band relationships.

The last sentence just above the "Minor Improvements" section is of particular note regarding the R3 design

"Another instance where a slightly larger pipe may help is where the departure angle of the pipe from the flange is very sharp (typically downward). The added cross-sectional area immediately after the flange apparently helps reduce the restrictive effect of a small radius after the port. This partially explains why some header models or brands work better than others with similar dimensions."
