Hey, So i'm currently trying to figure out if it would be possible to relocate my main cat from the downpipe to roughly 2ft further along the exhaust system without much issues.

My reason is i need a new exhaust and i've decided due to the cost to buy PPE headers which are catless but as i require the cat for my MOT, if it's possible to extend the wiring for the sensors and relocate the cat under the car at the next joining section which is maybe 2ft from it's previous location (Start of the cat to new start of the cat location)

My car is a Lexus IS250 (2006). New OEM headers cost more than the PPE headers so it makes sense to get the upgrade and just move the cat a little.

Besides needing the car to be a little warmer during the emmisions test is there anything else i should be concerned with?
