Exhausts

[tim2100]

Thinking about getting a new exhaust for my Fireblade. Its a 1000cc RR 5 (Under seat Can)

There is that many exhausts out there

Slip on
Factory
Full System
Link Pipe
Etc
etc

Now I'm not sure what will be beneficial to get. I just want something lighter and slightly better noise. More power would be nice.

What should I get?
Are the Power Commanders worth while? Is it worth cutting back on exhaust and getting a power commander?

Cheers
Tim.

i dont know how good the stock map is on those, but i doubt you'd gain much with just a power commander.
get a exhaust, full system for power, can for noise. then later get a power commander & dyno mapped to suit - then it'll run perfect for what its got.

There are two types, "Slip-on" and "Full System"

The Slip on is just the end exhaust on your bike (The big round bit at the back!) this is connected to the rest of your exhaust system via a link pipe (Which is usually supplied with the slip on)

Full system will be more expensive, and will almost definately need setting up on the dyno

Cheers for replies

I am seeing full systems for £1100+ for my bike and slip on cans for £145. can there be that much difference?

What just a 'slip on' can give any power/noise benefits?

Is a Power commander/dyno run needed for just the full system or are they better on slip ons?

Are you comparing like with like brands ? £145 is bottom end for an end can, and most of the favoured brands are £400 minimum. As for the full systems, they are a pipe bending work of art, and are made and sold in much lower volumes than cans which kind of explains the high cost. Worth checking whether the full system achieves anything for the £'s also. I talked to someone from a race team developing the '07 R1 who said they couldn't get any measurable power improvement over the standard manifold using a very expensive top brand race system.

It depends what you want...
Power or Noise... or both?
If you want power, then go to a performance custom building exhaust company it won't be cheap and you'll have to get it set up with a Dyno after which is a couple hundred more!
If you just want noise then get an end can.
I wanted noise & didnt give a dam about the noise, i went to my local auto parts place bought a Viper end can and link pipe, it was their last one and we're trying to get rid of if so did me a deal it was on the shelf for £120 but the link pipe was £15 extra.
They did the end can and pipe for £90 - bargain.
Sounds great!
Tbh if you have a 1000cc fireblade why do you want extra power? It's not like your going to be able to put it down on the road.
It might giv you maybe 2-5hp of which you probably won't even notice...

If you're riding on the road I can't see as you'd benefit from either weight or power. Noise can be achieved with an end can. I picked up my end ca off ebay for about 60 quid.

In relation to te weight part.
My stock can is literally about 5x the weight of the Viper i put on!
I'd say the stock can is about 8-10kgs!
It looks light but i couldnt believe how heavy it was!

That's not going to matter on the road though is it?

[lawrence567]

No of course not i was merely stating that the aftermarket one in my case was incredibly lighter!
I dont really care about the performance i have a 600 it goes from 0-60 in around 3.5 secs and to 100 in around 8 its fast enough for me!
I just got the new can for the nicer sound!

I think that's a fair point Dern. A lot is made about after market end cans being lighter but how significant is that REALLY for pure normal road use? Ok we all like a more fruity sounding exhaust but these days so much is made of bike balance & "mass centralisation" (to quote Honda) but what impact does changing the exhaust system have on those things?-especially on bikes with underslung cans -like new Blade. Surely it can raise the centre of gravity changing the "flickability" etc...

[tim2100]

Very true about the power and weight points. Will not notice much difference.

Mostly after noise and looks then. So looks like i will be after a slip-on can.

Cheers
Tim.

I'm not sure but believe that on the road none of this makes a jot of difference. Riding ability makes far more difference both on the road and on the track. Having said that I can sort of understand why people accessorise their bikes but a grand on a full exhaust systems seems like an eye watering amount. Having said that if you care about weight then from what I've read losing it off the wheels makes more difference.

Or to be brutal... and specifically in my case eat a lot fewer pies......

Indeed, I know wheels are unpsrung and what I am referring to is sprung, oooh err sounds rude, like the exhaust I know my quote does not quite follow but I was trying to follow the general point of losing weight from the exhaust..
