Guys, found the culprit of the sound...
Not the suspension at all. The mudguard must b lose when i repair the bumper last time.
Just now when to semenyih, can follow v6
Suppose can overtake but toll booth is in front.
Able to smoke the new city around 6-8 lamp posts
He picked a fight with high beam

He overtake me and i just follow behind
After that dun want to see him i just drop to 3rd gear and smoke him
Yesterday, tested the new muffler. Uphill not much different and able to reach 200. not so much stress.
But i like how the rev cut sound from the muffler.
Something like boom boom boom
This few days, alot of reckless things i've done

When i woke up this morning, i just realize if yesterday i hit a small stone, confirm cannot go TT.
rileks...la zuma nice sound u hv there.. n thnx coming for the tt guys!
