No expert but the holes are for the bolts that fix it and on your age of vehicle you don't need to remap. |

My 2010 preface lift has now completed 12 months 12k miles with EGR blank fitted, mot last week passed with 0.47 on the emissions. The blank is a solid flat aluminium plate, ie no centre hole. No software mods. Very happy.

Hello fredastaire...... also I have eliminated the turbulence from the intake manifold by replacing with a straight pipe, the engine is much better as power delivery .......... |

Hi cqr! There is no noticeable performance gain in removing the cat if you are at 160ps. You only get a very mecanical sound out from your tail pipe. (not much difference inside the car.) If you have remapped to about 200 then I guess the cat can be an obstruction, but I have not tried to veld it on again to check this. (It passed the simple MOT with good margin anyway ... ![]() |

Nothing else. There is no sensor on the secondary side of the cat. |
