Well this post is about inceasing performance of vits 2007-10.
I own a 2008 vitz 1.0. and i met a guy who cleans the catelatic converter without breaking it. iv seen many vitz with catelatic converters removed but their sound became really annoying. This guy charge me 2000 for cleaning it in front of my eyez. my car's acceleration has been improved from 30-40% along with fuel average. So i just thought to share it with u guyz may b it'll b helpfull for someone out there.
Ive also got his contact # if anybdy is interested or have queries may contact him.
