Installed HKS Jasma Large Exhaust In my Car

In terms of mileage and performance, technically it'll improve engine performance by allowing gas to move out quicker as compare to OEM muffler.
Straight piping is a good deal for extra loud sound but I'll not consider it because it'll effect engine efficiency, no doubt it'll improve performance but in return shorten your engine life and forget about good mileage with straight pipes.

I got this exhaust for around 8k from Gujranwala, its obviously not original hks but nor local Pakistani copy as you can hear the roar.

Rest I'll post more sound test videos on my instagram inshaAllah, here instagram.com/MOEEZAHMED4942

and yes you've to practice for driving with light foot again as this exhaust will make you forget about the ideal shifting rpm :3

Everything in this video is done with extreme care.
Do this at your own risk.
Use safety goggles and gloves wherever's needed.
