Since I got few PM's regarding this shop. It is located in Melaka and you can contact Tim 0172001336. I paid close to RM2k for it.I got my car a custom exhaust system. Exhaust manifold was maintained because it is already the tubular type. Exhaust system is made of SUS 304, mandrel bent tube, TIG welding and machined flange.
Overall I am very satisfied with the job done. Appearance, sound and build quality is good and they even did a dyno run on my car too.
