Hi,

I've justed fitted a set on TOR pipes to my 09 RIII and whilst they have improved the overall engine tone, I was looking to lose the CAT and replace it with a by-pass pipe assy (A9600160).

I'm not looking for a full-on Harley slash pipe sound, but would like a bit more growl especially in the lower rev range. Can somebody let me know of their experience of fitting a by-pass with the TOR pipes?

Are there any examples on Utube ?

I'm assuming that I don't have to have a second re-map of the ECU after fitting a by-pass pipe (I've already had one for the TORs)?

Cheers
Steve

Steve,

Just did the cat bypass/Tor thing a couple of weeks ago. Very easy and believe me, I'm no mechanic. I did get the Tor download which seemed to cause even more decel popping than without it.($45)
I do like the sound. Never tried it with just the Tors so I couldn't comment on the difference, but she sounds pretty nice - and I think fairly loud.
If you take a look at the bypass, I think you will see how easy it is. I just made sure I disconnected the battery, replaced the gasket on the cat side.

Thanks HIM,

Did you do the ECM re-mapp yourself (you mention $ 45) or was the charge from the dealership to do it?

cheers

Now that you have the TORs, you have to get the bypass. It sounds great. Remapping should be free. It takes 5 minutes. However, all of the stock tunes have power restriction so you need to get Tuneboy ($350) to download a map with full power.

Dealership did it Steve, but I would like to go with a Tuneboy at some point. Sounds like something I could have a lot of fun screwing up.

What do these cat by-pass units look like?
Are they only available as a genuine Triumph part or are there aftermarket ones available.
What sort of cost are these units?

Thanks

Paul.

Hi Paul,

Triumph make these by-pass pipes as an accessory for the US market ( http://www.triumph.co.uk/uk/clothingAccessoriesPopup.aspx?GID=2 ), but I get the impression that a lot of UK owners also fit these as well.

You can buy cheaper copies on fBay for a little less, but I guess if your bike is new and you want to keep the warrenty, you might want to stick with the Triumph parts.

On a UK legal aspect, I don't think there is any regulation (yet) that bike motors have to have a CAT (please correct me, if I'm wrong in this assumption). If that is true, does anybody know what the position would be if the legal requirement to have a CAT fitted is introduced in a year or two, and an owner has removed a factory fitted one?

Cheers
Steve

Very Happy with the TORS + CAT by-pass. To be frank adding the TORS by themselves was kind of OK, but it was the by-pass that sold me.

If you want that sound that's a cross between a P51 Mustang and a Spitfire, get both done. The bike now (to me) sounds like it should.

Brilliant...
