This is a real dilemma. If I want to lose the hot, heavy, unnecessary-for-the-amount-I'm-going-to-ride-the-bike chunk of metal for weekend track use, I can't without ruining the exhaust for street use. Welding that thing on there permanently creates an expensive, untenable exhaust fiasco. I could hammer out the guts for track day but then I can't put a new one on for emissions testing. I could cut it off but then it'd have to weld it back on. How many times can I do that before I run out of material to weld? I'd buy the H2R exhaust and swap it out but they won't sell it to me.

They wouldn't really do that to us would they?

I believe there are some new anti-tampering regulations to blame for this.

Just change the whole exhaust system ... doesn't have to be for the H2R unit ... Tracks around here that are worth riding all have noise limits anyhow that the H2R exhaust won't pass, it will need a muffler.

It's also quite likely that the catalyst is not restrictive even if left alone.

It's my understanding that as a general rule, Slip-On's don't really do much regarding actual increases in performance numbers.

However, according to Akrapovic regarding their gag... gag... looking Slip-On:

"Making the most of the Ninja H2’s power, this unique system will deliver optimal performance from the bike and add even greater appeal through its innovative design. The Slip-On exhaust system is supplied with a light-weight carbon-fiber bracket and an easy-to-follow mounting manual. This plug-and-play system needs no remapping or other parts to make the Kawasaki Ninja H2 an even greater machine."

The Akrapovic web site still has no Dyno comparison to the totally Stock system on the H2 versus this Slip-On.

Akrapovi?

I am sure the bike will make big power with a CAT in place, as soon as the ECU flashes are complete and open the bike up it will help.

This bike also has a exhaust valve and servo so you know kawi will be closing them up. Will be interesting to find out when they do that.

Regardless that thing looks like it weighs 20 pounds. It's a giant titanium (or stainless?) brick tightly packed with honeycombed steel. Must. Go. Away. (And when I said 'track use' I was trying to be politically correct. Wink.)

you could flange it if you're up for the work?



If only I had a monkey...

Yeah would be very easy to get a flange welded on to get rid of the headers.

Most people buying these bikes will have no problem putting a $1,500+ pipe on the bike though.

You could always buy a spare set of stock headers..... MSRP: $1,669.60 LOL


Yes the header and Cat's are one piece :-(


I'm planning on doing this so I can mod the exhaust and maintain the original exhaust for future use. :D

Just buy an aftermarket and then keep the stock one around for emissions!

Lucily in Florida we have ZERO emissions so you can run a straight pipe if you wanted to.

For me it's not so much that the cat is restrictive as it really sticks out and takes away from the beauty of the bike. With the stock muffler you just don't notice it as much, but look at the pics with the Akro slip-on, the cat really stands out. :eek:

There is something to be said leaving the cat on....with a super charged motor it's not as important like with a normally aspirated motor. For total power yes but I think we'd be fine with it in place. I have a CTSV with a bunch of mods and when I finally put a full system on my torque dropped enough to feel it at low rpms for sure. Now granted the peek HP went up big time... I want the cat off for sure but I really want someone to come out with a full system early this spring I'm not sure how long I can wait taking off that stainless steel anchor.......

I know everyone is saying it's a catalytic converter...but is it?From what the literature said,it's pre-exhaust flow chamber...something like that...I didn't see anything mentioned about a cat?(although we KNOW it has at least one)I presumed it is in the exhaust mufflers like the 14R.

Found this:

"A single exhaust silencer on the right side, combined with an under-engine pre-chamber, replaces the race-type open exhaust of the H2R."

Is 'pre-chamber' code for counter weight?

and in my couriosity i went looking for the price of the supercharger ...


omg :) 2533 euros plus 21 percent taxes !!!
Will, if you could it would be great to see the parts/price list in its entirety, perhaps its own thread, H2 replacement parts and cost? :D (that is if you won't get yourself in trouble doing so...:D;))

Cheers!
