Y CK got bad reputation? price r high, and no professional modding standard. I was once their customer. Was quite noob and young that time, 2-3 years back. I asked them to recommend some good exhaust system for my car since the old one was about 7-8 years old already. they changed the hotbits manifold, 2 inch piping, center swirling bullet. For all that they claimed can increase 35% more horse power to my 4G13p! think back i felt quite stupid also hahaha. The boss recommend alot stupid mod for me lucky that time i dun have enought money to go further. Even his ex-worker also advise me not to go back there. Their objective is just to earn money. This is based on my personal opinion and experience.
I've also asked some of the mechanics around that area, most of them gave bad comments mostly due to price factor and unproper mod. I dunno how other malaccan think about it...mind to share?
