Which exhaust system / can do you use?

Madaz twin cans on the ZZR600 . $900.00
Wanted the performance & NOISE, but keep the original styling of the twin pipes.
Mechanic tells me it should be rejetted, rough at idle (no efi).
She now pulls smoothly from 2000rpm, give it a fist full at 4-5000 rpm and the front gets very light, lifted it once without trying.
The cagers now know I am there

Don.

i have a Pipemasters 4 into 1 on the 9R. It sounds beautiful and makes delicious power. plus, its australian made, and that counts for lots. apparently the system was designed for the first series of Formula extreme?

unfortunately i have a 2000 model engine i am about to put in so the headers wont fit the 98 cylinder head (the newer ones are larger). i think i'll get a quote from pipemasters for a new full system.

I have a Kerker, but hopefully I'll have a Yoshi soon.

On my Kwakas:
1980 Z440 some cheapo Chinese megaphones which still look like new after a year of abuse- cost $150 for the pair!

Why did you choose it? El cheapo is it a style thing? yeah they look good. was there a noticeable difference? Ummmmmmmm yep it had hotdogs on it which were rediculously loud- still nice note but sociable. How much did you spend? $150 Did you dyno before and after? No....did you have to make any carburetion changes? No. Any intake mods? No Would you choose the same again? Yep they are great
What did you fit it to? 1980 Z440 Kawasaki

1986 GT550 Transac 4 into 1 with alloy muffler

Why did you choose it? On the bike when I got it. is it a style thing? Guess so. was there a noticeable difference?N.A. How much did you spend? Nuffin! Did you dyno before and after?No did you have to make any carburetion changes? No Any intake mods? Foam (I made it!) airfilter- original one had perished.Used proper filter foam ,cut to size and glued on Kwaka airfilter frame Would you choose the same again? Yep sounds great, quiet enough but loud when you get under it- best thing is you can't hear it on the highway so the sound doesn't annoy you on a trip, but sounds good around town.

2003 ZZR1200 - Staintune oval slipons

Why did you choose it? Good product that outlasts the bike and to get rid of HEAVY standard mufflers. is it a style thing?No I prefer the look of the stockers. was there a noticeable difference? Oh yeah! Particularly the weight but a bit of pickup to. How much did you spend? $900 (trade price) Did you dyno before and after? I dynoed before- 139 RWP haven't after yet-would guess around 145HP. did you have to make any carburetion changes? Yep just turned my flo-commander knob. Any intake mods? Nope apart from removed carby heater/water plumbing and reed valves in valve cover as well as adding a flo-commander. Would you choose the same again? Yep very nice pipes.

What did you fit it to? ZZR1200

i started out with a akra slip on had it dynoed got 132 hp, sold the slip on to a fella who's names slips my mind(it will come back to me i'm sure) then went full akra system , waited a while til i got the jets done due to $$$ shortage ,it was running a little lean and playing up at low revs, had the carbs off 6 times to get the jets right on the dyno, what a difference, although i'm down to 19 k's per litre now from 21kpl maybe coz i'm giving a bit more of a hand full getting used to the front wheel being off the tarmac , had the same full race system on my 98 ninja zx9r but got 142 hp out of it, maybe coz the ninja was lean and mean haha
cheers lins

akra on the 7r.

142hp eh... whos dyno was that on krafty55?

would love to see what my 9 is making now

It was done at race replica brooklyn, had the ignition done too

If u go back to race rep tell them lindsay sent u hopefully u'll get a good discount ask for rhys, the ninja had an ignition advancer fitted

I have an IXIL muffler. It was on the bike when I got it, somep eople like the sound, some people don't. I think it sounds ok, but will have to let someone take it up the road and back, so i can hear it from a bystanders perspective
