Well, I'm new to car mod and not sure is there any different performance between PZ and Cap Ayam brand. Physically, I see not much diff but PZ said their is length tuned, etc...

Any idea/comments?

My first impression after reading the forum on PZ was most of you all commented OK/good.

When I went to PZ, I saw their workshop messy & un-organised, then the guy did a demo on the vacum, blowing the air from ori and then PZ 4-2-1. I can feel the PZ have stronger air blowing out compare to ori. (well not sure if the ori extractor was blocked somewhere in between, commercial trick?)

Anyway, I installed it after listening to the guy explaination.

But my impression was not good when they do not installed it at their workshop but sent me to another exhaust shop nearby (saw lot of design there and cheaper too!).

They do not have the proper jack/machinery to repair underneath of car. Wonder what can I expect from such a workshop and whether it can increase my car performance or not!
