Thinking about going full de-cat, though concerned about the front pipe as it has 2 sensors on it, pre and post cat.TSL have a Group A pipe available with inbuilt bosses to re-use these, does the 2nd sensor at the bottom need the cat inorder to function correctly with the ECU or as TSL said " don't worry it is only an exhaust gas temp sensor"
Car is an Import RA MY97

Thanks in advance

The cat over temp sensor can be disconnected at the plug and forgotten about. It won't raise a "check engine" light if you do.

Many Thanks

if you replace the stock pipes with high performance ones, especially de-cat'ed, wont you get a Boost Creep?

i have been thinking of doing the exact same thing as you, but the only thing that stops me here is possible creep.

best regards

did not notice you have RA.. ok, then no boost creep obviously..
