Re: Fireblade 08 - Aftermarket Exhaust

I don't think anything I've seen is worth the money yet. Your biggest gains will come from a metric calibrator (US box to get the missing UK power back) and a PC with a custom map.

Curious about the losing power down low comment - do you know this to be true from a dyno test etc? How much does it lose and where? If so, I might reconnect and see if I can notice any difference.

It doesn't really show on the dino but when you disconnect it to me it feels sluggish picking up, try it

Re: Fireblade 08 - Aftermarket Exhaust

Here's mine with the Akra race slip-on (basically the race version does not have the valve). It does come with a noise reduction insert but I've never had it in. The pipe sounds good, is light and pretty much gets rid of the flat spot. So there's no panel fill in but to be honest you only notice this if you look at the bike from waist height.

Very nice. They also look good in carbon fibre.

Re: Fireblade 08 - Aftermarket Exhaust

I have been looking at the Two Brothers Pipe and Juice Box, does anyone have any info on this setup? I am put off with the lack of belly pan, the Taylormade is nice, but I have read it is very loud, is the two brothers one loud too?

Thanks ............. Hoody

Re: Fireblade 08 - Aftermarket Exhaust

Personally I think the Taylormade looks the best. My buddy has his on '07 Gixx 1000 and looks and sounds good. A little loud but nothing to bad. He had a dyno run and his looked pretty good but I'm not sure what stock was like.

WooHoo A New Year!!!

Re: Fireblade 08 - Aftermarket Exhaust

I Dont Like The Looks Of Any Of The Aftermart Pipes

I bought a Stock Muffler Off E Bay 95.00 w shipping

I open the back up and took out the plate over the main baffle

Took it to my welder buddy

Bike sounds Awsum.

With the cable off top plate stays open,however servo motor has to be set as per manual or you will be in limp mode.

Any one interested in how i did it e mail me .

a decent slip on may or may not give you a few more horsepower but what it definitely will do is improve your power to weight ratio (to the equivalent of gaining a few extra horses), remove the flat spot (if you go for a race slip on without the flapper valve) and improve handling.

let's face it, there is no way that Honda would design the exhaust they have on the Blade if they weren't facing such strict noise and C02 legislation.

maybe the stock exhaust looks ok, maybe it looks slightly better than most aftermarket pipes but guys, this is a superbike and the OEM pipe is totally counter-productive to anything that anyone would include in the original design. maybe the Blade would look nice with lots of chrome bits and forward foot controls but somehow i don't think that's the point.

maybe it's just me and maybe not everyone buys a superbike for the performance? otherwise i guess roland sands wouldn't be able to sell his chromed and extended swingarm creations.

Weird, how can you say the original looks better than this plus this sounds amazing and makes an extra 12bhp through the range
