Royal Enfield — Problem with Engine sound

Address:

Basaveshware nagar 13 cross A block Haveri

My royal enfild himalayan bike has completely different sound compared to other himalayan bike. I visited the royal enfid showroom and the mechanic told that frequency need to be reduced to get the normal sound of the himalayan.I did not change any exhaust. They directly told that there is no change in sound without checking the defect.The warenty is there, I need my bike in good condition not the defective one .
