You Ask/You Answer: Which exhaust?

I've just got my first 'big' bike – a 2002 Honda CBR900RR-2 – which is currently completely standard, and I really want to pull some power out of the motor. I've got a Power Commander for it, and am looking to buy an exhaust end can, but the choices are baffling. I've found loads of cans from £100 to £500, but have...

Unintended Pun ?

It struck me as funny when the article said "the choices are baffling".   :biggrin:


Anyway back to the question: Is the choice to be made from road-legal end cans? Assuming it is, I had a 2010 Blade with the Akrapovic can which has a Honda part number and meets all current legislation. It gave a decent weight saving, sounded really good and looked the business too.

Going off-topic a little Snev and Hosbusa mentioned the ZZR1400. I bought a 2012 model and have just fitted a Brock's CT exhaust system, a Dynojet PCV with 02 Optimizer and fuel maps, a reflashed ECU by Don Guhl and a few other goodies. An identically modified bike owned by a friend made 202bhp at the rear wheel on our local dyno last week. There's also the 30lb weight saving over the stock system to consider because the result is a pretty good bike made totally brilliant. A Kawasaki employee has already had a stock 2012 ZZR over 200mph, at Elvington last year, we're looking forward to running our modded bikes there in March.

That ZZR14 with over 200 rwhp sounds amazing ! You gotto crack the double ton on that? That kind of power with the right fuelling is amazing.

I haven't been to Elvi for a good while. Mind you its a bit of a treck for me now. I'm closer to the other top speed event if you know what I mean.

Do you get down Santa Pod much? I'd like to see that on the strip !! Mind you, probably have to stretch the wheelbase a bit.

snev, my bike was low on power to start with for some reason. I have heard of stock Gen 1 Busa's making over 170 at the rear wheel. But they are not all the same power output even when fresh out of the crate.

The biggest and most significant improvement is the huge increase in rideability ! It makes these high power bikes safer to ride when they have all the restrictive crap removed. The Busa can be an absolute pig on small throttle openings and stutters and farts when trying to manouver the big tub in tight turns and mini islands and such like. When you try and give it a fraction more throttle to get it to move smoothly, you end up giving it too much and its all because of all the emissisons and restrictions tat they have to put on them. These motors run best when they are free breathing. I reckon modest performance mods with a good dyno set up are worth every penny just for the improved rideability !

My second Gen2 Busa makes 177 as stock at the wheel which corresponds to the 197 crank figure officially quoted by Suzuki, all told I have amassed @ 86000 miles on my 2 Busa's in 5 years also owned an 06 ZZR1400 and an 05 Blackbird all new when purchased. I also own a number of other bikes and a couple of special cars so I can spread out the miles depending on my mood. In total I have owned, Ragged and enjoyed riding 47 Bikes without being done for speeding once. Touch Wood.

Dunno about what exhaust for a Fireblade but going all nostalgic, I can hear 2-stroke MX bikes and my own commuting and weekend dirt fun DT250 with a Fresco... and if I listen hard enough I can hear RD's and KH's with Allspeeds........ahhhh happy days.

getting a bit of a wet patch

A standard RG500 is glorious. That's before you stick on Jim Lomas or Jolly Moto's. Oh God these were great days... courtesy of mircomoto on you tube. http://www.youtube.com/watch?v=XyC5RBCwknI

ah yes, the NS400 was probably the worst ever 2 stroke sound track. It sounded like popcorn being made in a tin can. There was no real oomph to it. I may have to buy a KH with allspeeds now. Not to ride though, just to listen to in the garage :)

best bang for your buck

If your just looking for a better sound for you Honda any slip-on will do try not to go to big with the core as it will be too loud and loose too much bottom end which is what you want on a street bike everyone wants the big horse power figure but torque is the key loose torque and the bike will feel slow ive been building superbike/supersport race engines since 1999 the best thing you can do is air filter K&N DNA BMC with a pipe full or slip-on depending on the coin you wish to outlay ECU Tunning is crutial in getting the best out of it once the mods are done then get it properly tuned dont just upload a map from off the net because it wont be right take it to a authorised tune shop custom mapping is very important you can set it up for full power fueling when you want to race your mates or lean it off for the h/way runs
