Replace One Exhaust system with Two exhausts

[k0d]

Hi, I've got an vauxhall vectra 1.9CDTI SRI 150 2007 and I want to replace the existing 'one exhaust system' with two exhaust (like the 2.2 petrol) but I am wondering if this will make my car consume more diesel and will affect my insurance.

Moved to the correct section!

Yes you can fit a twin exit exhaust. It won't affect your fuel consumption but you should tell the insurance as it is a modification from standard.
