Just got off the phone with Jardine sales - aftermarket slipons. They don't sell a full system. When asked why, his reply was, the factory headers are more than sufficient. The problem? They're over a grand for duals. He said we only sell them in duals when I told him my intention was to go to 4-2-1 and won't be needing the second one. If you ask me, these fellas are shooting themselves in the foot.

So, my question to the group - is there really a significant gain to be had by switching to the aftermarket headers? I know the aftermarket titaniums are lighter, but for sheer performance gain, what's really to be gained here?

Thanks for any of your insight.

don't just listen to anyone on this subject as just about everyone will tell that 4into1's are better and for what reasons common sence tell us this dual exhuast pipes move more gasses out of the motor (air pump) and 4t1 moves it at higher speed I myself don't know all the reasons but even suzuki started putting then on there 1000 to help move out more gasses now if you want to ask someone who may know why duals may give more hp than say an every day 4t1 ask brock how and why the ct duals came to be now if it where for just 1hp more than the single do you think they would produce them, just for looks ??? now as for the sidewinder type ex for one its a ground clearence thing two they look cool on drag bikes lol now I am not saying 4 single pipes are the way to go but dragsters use 8 thats the majic number I don't think you will find much gained from getting after market header except that some models have catalytic converters and that is an air restriction some guys have removed it mine was never there aswell the stock header has crossover tubing to help with scavenging as well as Tq now if you want a 4t1 stock header look for the one off the c14 as it is single sided or you can just cap that sucker lol like some have done nothing wrong with that just "funny ha ha" hope that helps a little

hmmmmmmmmmmmmmm.Ok, I will only give you my reasons. Muzzy Slip-ons = 4 to 5 Hp Gain. Full system = 12 to 13. When I removed the slip-ons and installed my 4 into one set up and then went for a ride,,,,welllll,,,, the smile on my face could not be scraped off with a chisel. I spent allot of Money to learn this lesson. If I would have listened to others I would have saved a few bucks and allot of time in the learning curve.

ask brock how and why the ct duals came to be now if it where for just 1hp

1hp more than His 4 into 2, then into 1 system correct? The CT Duals make Shitloads more horse power than any set of slip-ons, correct?.

I hope my explanation of why I switched, answers your Question(simple). I know all the Black Magic is done with Header and Mid pipe research. This is where the power is made. I hope hub or some of the others will give more detail. Sorry I'm not that guy.

brocks ct duals give you a 26.1 hp gain over stock according to the dyno chart they have on thier site

26.1 hp gain over stock

That is one big #. Are you sure ?

heres the chart

http://www.brocksperformance.com/dyno_charts/ZX14%20CT%20SERIES/ZX-1406_CTD_vs_AH_PEAK_800.jpg

Full system is just plain better.

My brock's pipe is 4-2-1. Couldn't be happier.

heres the chart

This graph starts off with a bike making 161 Hp. Most Start with a 174hp or a little higher #. Sorry it was just a bit of a shocker for me. I was thinking 170 or 175 then add 26.1 = WOW #'s Lol. Slow, you would not need Nos lol. If Brock says the CT Duals makes one more hosre power then his 4-2-1 systems You can be sure they do. Point is still the same, Jardine slip-ons will not make #'s like the ones listed above. I guess it's all what your after. I just think if your going to spend the money you should get the most hp possible for it. I love those CT duals. If they were around when I was looking they would be on my bike today.

believe it or not but the KR TUNED slip ons claim 11hp over stock the most hp of all I believe and their mid pipe design dose look different than most I've seen they where very costly but now you can find them around 500.00 bucks there was a pipe compo in one of the post either here or on another site that put quite a few pipes on bikes then dynoed them to get the out come in numbers MY FACTS ARE NOT CORRECT HERE THE COMPAIRO I SPEEK OF IS LIKKED BELOW OR YOU CAN JUST LOOK UP SLIP ON COMPAIRO ON GOOGLE ITS LIKE 16 PIPES THEY TESTED

If you find it xxxxses that would be great to see. I love watching that stuff. What kills me is the stories about about 195 horse at the rear wheel with just a pipe install. Then off to the Happy Dyno and what do you see, 175hp how does this happen ?

believe it or not but the KR TUNED slip ons claim 11hp over stock the most hp of all

If so, these would def B the hot ticket in the slip-on Market and a really cheap way to get 11 ponies, Yes ?

This is a good one. Lots of good info if your looking. No one here is making 187 Rear Wheel Horse Power. Click Here, Cheers

Mine made 194 with a brock's smeg

Just a pipe and nothing else.....? I thought you had the thinner head gasket and that funny fuel? hmmmmmm. The nice part about the video it was a good group of guys all on the same dyno on the same day. I don't think you will get a stock bike with just a pipe running on pump gas and that's it to make 194hp. Or not on that Dyno anyway. Slow what did your bike make before the gasket change? I'm still toying with the idea anyway. Snow here brings me down. Booooooooooo.Lol

ok I found the slip on compairo seams i was mistaken about the KR tuned pipes what i read was 11hp gained but what it says is 1.1 Tq gained and with the totals like 3.1 hp and 1.7 ft Tq Even I can admit when I am wrong SORRY GUYS I misquoted what I had read but I still place all the faith in dual ex for this beast although the ct duals are way out of any price range I have for my bike they do show how they compare to whats out there as far as perfomance. Now they are really 2into1's side by side not 4into2's ok here is the test on 16 slip-ons
http://www.superstreetbike.com/tested/0802_sbkp_slip_on_exhausts/index.html

AND FOR THE RECORD I WAS NOT SAYING THAT CT DUALS ONLY GAINED 1HP OVER 4INTO 1HP I WAS SAYING OVER CT SINGLE WHICH IS JUST A NUMBER I REMENBER FROM BROCKS WEB SITE AGAIN I COULD BE WRONG HERE ITS JUST WHAT I READ NOT WHAT I KNOW

I have 4 bikes in the stable and 4into1's on three of them they do make tons of power none have been dynoed

Don't be sorry, we all get things wrong somtimes. I like it when the guys point out when I'm on the wrong track. It usually saves me money later on down the road. Sometimes I still don't listen and later wish I did LOL.

Why 4 all the yelling ?

Have any of you heard about a guy in LA named DePalma? He runs DePalma Motorsports. Basically, he requests that you send him your factory exhaust cans and he will chop them, power-coat them black and baffle them differently to allow more flow for around $300. They actually sound excellent. Here's a link for youtube:
http://www.youtube.com/watch?v=EzknUwdHiVQ

Doesn't look like he has a website. What are your thoughts?

is there a 4 to 2 replacement for the oem available? i already have yosh slip-ons and want to rid myself of the cat but want to keep my $ spent on the slip-ons

BrSwift welcome, there is a thread here somewhere where one of the members cut the pipe in front of the cat,removed the cat and welded header back together. easiest way though would to be to by a 06 or 07 header for $100(what ive seen them go for on ebay)and swap out the header

Br here is that post i mentioned

xxx you are correct the ct duals make just under 1 hp more than the ct 4to1

http://www.brocksperformance.com/dyno_charts/ZX14%20CT%20SERIES/ZX-1406_CTS_vs_CTD_800.jpg

CT Duals are not slip-ons,They are complete systems,2 into 1.left side and 2 into 1 right side

yes and as far as i know they are the only full dual exhaust for the 14..might be why they cost $2000 lol

My bike stock made 158 rwhp. Tuned it, made 161.

thin head gasket, degreed cams, race fuel, and brock's pipe made 194.

The jump from 158 to 194 must be flipppppping AWESOME. I look forward to reading your new #s when Your bike is finished. Envy I have. Cheers.

Laughing at Romans - "Envy I have". Around the battlefield, a perimeter create. Thanks for all the good info gents. I've decided to go with Brock's CT 4-2-1 full system. I just prefer the single can over duals for some reason. Two just looks gaudy to me. Good info all around.
