Fitting Cat Free Exhaust and Air Box Mods

[beardyweirdy@me.com_imp]

Hey All,

I'm planning on fitting an Arrow Cat Free Exhaust, TSR Air Intake Funnel and TSR Air Funnel Kit, later this week. I have the parts and I'm just waiting on some Exhaust Gaskets.

I've got a couple of weeks off, the weathers fine and all the bits are in place, except I don't have a Workshop Manual. I've had the tank off a few times before and I know my way around a bike, I'm quite handy on the tools. I just wondered if anyone had done these mods or had the air box out at least, that could offer any tips or help.

I know the Air Funnel Kit will require some cutting and drilling. I think the TSR instructions should cover that. It's more the disassembly of the components.

I was going to use 'The Force' and I'm sure I'll muddle thru, but any advice I can get that will save some time, frustration or general bodgery would be appreciated.

I've tried getting hold of a Workshop Manual in the UK, but the dealers I've tried won't supply them. The only way is a purchase from the USA but it's not going to get here in time.... Or, if anyone knows of a PDF of the relevant sections online, then that would be cool.

I'll post the results of the mods when I get it dyno'd. I've got a PC V and a Flashed ECU so it should show a fair change when done. If anyone's interested I'll post pics of the Mod as I do it as well.

The bikes already had most of the cosmetics sorted with a White House K10 Kit and a few other bits and bobs, I'll post loads of pics when it's finished..... I know, it's never finished ;-) but it's getting there...

Thanks
Kev

Keep us posted! it's my understanding that the air funnel kit requires a lot of disassembly to access the OEM funnels plus you need to enlarge the holes in the throttle bodies. Hopefully someone has done this and can help.

The exhaust and air intake funnel are straight forward installs. If the arrow exhaust uses springs to connect the header pipes to the collector, a spring puller may come in handy.

I have a cat free exhaust, TSR air intake funnel and PCV but still have the stock 25mm air funnels which are the main bottleneck.

I hope you can post some pictures of the install and share your dyno results.
