We have now released our KTR 3" decat pipe for the Megane 3 RS 250/265/275 models. It is made from 3" bore stainless steel and it is a direct replacement for the original restrictive catalytic converter. Comes complete with the all important mounting brackets fitted. (Gaskets not included)
Once fitted you will find that boost builds quicker and the car pulls much harder through the rev range. On our own RS 250 we gained 13bhp and 17lbs/ft of torque in the mid range which is very noticeable. The exhaust note also takes on a more purposeful growl which sounds superb.
We would recommend have the car mapped or the ecu program adjusted once the cat is fitted. You will also not pass an emissions test with this part installed and you will have your emissions light come on for now but this could be switched off as part of a remap.
With a revised design for 2018, these are now fully tig welded!
