@rcannon409 did the y pipe he made eliminate both sections of catalyst. The forward section in my 15 was right after the collector with maybe 4" between the end of the down tubes and the start of the first catalyst. All of the Y pipes I've seen out there only eliminates the second catalyst section that is partially (maybe 1") inside the muffler.

Yes, he did. His thread is still on the z1000 forum. The members name was "repair"

That was interesting, seems the 3rd gen Z had 3 sections of catalyst.
I liked his jig.

Makes you wander if the guy that dynoed the y- pipe had a tune and like Avintage hit on was all the converter removed. Delkivich has a dyno on the n1k in its site but I couldn’t blow it up to see the numbers. They do advertise an improvement in hp. But I think 300 bucks is a good bargain to get rid of the heat. I would rather have that set up than cutting and putting in a y- pipe. Maybe Novak’s 43 will get a dyno run done. Sure if your after every ounce of power then you need increase the price 2-1/2 times to obtain the Akra headers but I’m not so sure your going to notice that much difference between the 2 if the delks say increase by 5 or 6 hp

I'd like to lose some of this heat for sure. Maybe as RC says a few more bucks net you a bit more gains, but at the very least I want to lose some heat.

If that delk header is the same size as stock, the gain wont be anything. If performance is the goal, spend an extra 300.00 for something that will perform. You do pay more, up front, but you will get that back if you ever sell the bike. If it's only heat, or weight a person cares about, the delk makes sense. Performance? Probably not.

Rock, is the heat Concours 14 like? Ivan helped the c14, a lot, but it's still a hot bastard when it's over 100 degrees out.
RC this Ninja is much hotter than the others. It runs pretty hot. I heard another member complain about the 2018. I forget the reason but there seemed to be some explanation. WIth the temps lately it becomes unbearable at times.

I dont know if the header if going to do THAT much, for heat. Sure, every little bit helps, but the hot exhaust is a symptom....not the real problem. Plus, if a good flash ever becomes available, 100% chance it will be based around the Akra header, and not a Delk. Still ot would be a nice upgrade to use the Akra header and the stock mifflers.

A tune was also part of the y pipes problem. Repair had dyno access and a power commander. He ended up even. If you have to pay to have a tune to be developed, there go your savings on the y pipe or delk header. Plus, why bother if you know one of the components is not correct?

He did eliminate all the cat material, which is not awesome, either. The cat is oversize, so it wont restrict flow. When the material is removed, that section becomes way too large.

I’m going to question the part about the n1k cat being over sized, I know the kids 400 exhaust flow is 5 times more than mine with the brawlers, hers moves the turn signal and you can feel it 3 or 4’ back, mines like blowing through a straw compared to hers. I thought the heat on the n1k come from the cat and bread box. Usually the cat gets hot on
most vehicles. RC that sounds like a democratic carbon footprint ploy you are putting out.

Go to pt today and tell the therapist that this puts week 8 under our belt and I’m not happy where I’m at in this whole process, he says this injury takes time, he said you couldn’t lift your leg if the ground when you come in, I said yep but I’m tired of working from home, I want to ride my bike, I’m tired of hurting and doing these dam exercises all day.
He said I’m going to get hold of you
today. He pulls out his piece of
stainless plate and starts rubbing it
over my knee cap with pressure,
then he says get on your stomach
and he pulls my leg up towards the
back of my head and I’m like dam,
the other therapist said he his
cringing pretty bad, I said hell your going to cripple me worse than I am, he measured the reflextion at 107 degrees up from 97. That fucking knee is so sore tonight I can’t hardly walk. I ditched the brace this morning because I got to come out of it sooner than later, it’s mainly for protection now anyway. I can finally take a shower and put all my clothes on by myself and tie my shoes is a struggle on my bad leg, they made me come out of my slip on house shoes I been wearing for 8 weeks, I told him if other parts were as stiff as my knee I’d be hard to recon with and he grinned.

Good deal Mark. That's the attitude you see in people who come back better and faster then expected.

One of my all time favorite NFL players was Bill Bates, he was one of those all around good at heart type of guys. Gave 110% on the field and 90% of his free time off of it to charity. He was voted numerous times by his teammates and fans as best leader on and off the field.

In his first year 1983 he ran a 4.8 40 and barley made it as a walk on with the cowboys because that's the team he wanted to play for. Coach Landry said yeah he might have been a little slow but hes the only player I had to ask to quite hurting his teammates. Won NFC speacial teams player of the year.
In 84 he went to the pro bowl and was selected All Pro.
Skip forward to
92 mid season he tore a ligament in his left knee, and at first some though he wouldn't make it back. At the very end of taining camp in 93 he ran a 4.6 and acted like it was nothing and that he should of always been that fast.
When asked how he did it he replied...... because I wanted to show people I could.

Bill Bates was an amazing player, and sounded like a good guy, too.

Mark, I'm not sure what the Democrats think about my gutting a cat, or it being oversized..but, I am pretty sure about what made power on Ivan's dynos, and what did not...in fact, he put the results on public display so people would see if the added power was worth the cost in switching out the stock exhaust header. He did not publish the result of how hard the exhaust appears to be shooting out of the pipes. Maybe that's coming for 2020?

A person should buy whatever system they want, and maximum power is not where it's at for many people. It's been a fact, since late 2010, that the stock header tubes were too small to make excellent power. When someone produces a copy of that undersized system, what sort of magic would be involved to have it make more power than stock? How can it?
