i was just curious about "real world".i didnt see sportrider test a 9 with an akro,maybe i missed that one.If they did these mags are sometimes so right on and sometimes so way off!

but thanks for the feedback,and if you get around to it post your's when you get a chance.

02 zx9r

with Acrapovic exhaust "sport production" (eight pounds less than stock pipe) i.e not race version most people buy

peak increases

10 hp 1.3 torque



Looking at dyno sheet

everywhere but 9g to 12g power is pretty much the same

but the delivery seems to be smoothed out.



they also put pipes on the 954 and gsxr not acra's they put out only about additional 6 hp

but that probably doesnt help you.

I will keep a look out and see what else gets in print.

You might want to email the guy with the 998cc in ebay and find out why he chose the muzzy (although i read somewhere that he is not the one who did the work.)

good luck

Akropovic; it is the only 4 into 1 pipe for a zx9. i have had a muzzy, d&d , and now an akro. the d&d sucked. it leaked like hell , was loud, and and did not perform as well as just a slip on and a stock head pipe.The muzzy offer an increase in peak hp but sacrificed midrange and was loud.The akro offered greater peak hp, drastic midrange boost,and sounds great.the akro was a bit pricey but was worth the extra $.

I recently installed a black to green faded micron slip on to my '02 zx9r because the serpent headers aren't available for carbureted bikes, yet. Prior to that I ordered a full system from HMF Engineering with a beautiful black powder coated canister but they sent the '01 version. I have a buddy who went the "conventional" way with good old Muzzy. With the full Muzzy ti system and rejetting, he's claiming gains of 7-8 hp on the dyno. I did read the article with the Ak system adding 10 hp to the bike but unfortunately, the pipe is yet available... I checked!!! If you want to avoid a migraine, refrain from dealing with the following companies and their customer service departments: HMF Engineering, Micron, Wolf Exhausts, Boss Exhausts, Lockhart Phillips, and Quill... None of 'em have us on their "to do" list!!! I learned the hard way!

I used an Akrapovic pipe on my 2002, which in my opinion is the best choice.....(the pipe for the 2000 + 2001 model), it fits perfect.....no adjustments or other issues at all.



It's a 4-1 w/merge plate and crossover tubes.....it pulls very well out of the bottom.......no dips anywhere, after installation of a 4 degree ignition advancer and my carb kit, it made 140hp + with great low end and midrange. The top end above 9000 is awesome !!



Handlebar vibration is very low and the closed to part throttle problem is also eliminated.



Similar results can be had with a Slip-on........More midrange than a full exhaust up to 8000, but slightly less peak (2 to 4hp).



If you look at my website, the 2000 + 2001 dyno charts are nearly identical to the 2002 model.....

(no charts on the website yet for the 2002 model)

Where can I find a used slip on for an 02? Prefer carbon fiber but anything would be considered.
