Thanks for the link Ray it looks interesting. Just in the process of registering so I can see the pictures. If it's too much hassle I'll keep swapping between the termi's & standard depending on track noise levels.

The reason for looking into this is that my Termi is showing signs of overheating after only 4500 miles & I was assuming that it was caused by using the db killers on quiet trackdays also db killers should be called hp killers as a restricted 125 could pass me with them in.

The main reason for the de-cat was because I wasn't sure what the results of having a rich mixture was likely to be. I know a weak mixture destroys cats which is the reason for lambda sensor but didn't want a rich mixture to block the cat.

I'm no fan of DB killers, i wouldn't be surprised if they are the cause of damage to the carbon sleaved termis due to the excess back pressure they cause.

I'm my experience it's over rich fueling that does for a cat, they certainly don't like unburnt fuel on them at all.

Yep it's hassle swapping systems depending on noise limits, one reason why I don't do any quiet days!!

Maybe it;s worth looking into one of those new fangled Motty fueling thingies, it's reckoned to adjust fueling based on readings from a lambda sensor.

It's absolutely pointless running db killers as the exhaust ends up being even more restrictive than standard.
As long as excessive fuel eats the CAT rather than blocking it I'll be happy.
I'm finding that a lot of weekend trackdays are 98 - 100db & weekends certainly work for me money wise.

With my ability I don't really need any more power on a track so I'll stick with the DP ECU or go back to standard & see if I can flog the Termi.
