Horn is easily available @ Rs. 200/-. Sound quality is great. btw in my opinion original silencer looks cool 
Thank God, no strange noise is there so far
After reading your post in checked the rear cowl. its fixed and tight.
Yes. cosmetically Dream looks very cool and to some extent, sporty. Customers response is very low. What I think is that there is "BHAIR CHAAL" in pakistan. So people dont give importance to new products. Secondly hathora mechanics are also the reason. They always advise that older product is good. New one is crap. Once I went for a mechanic to lubricate chain, he said to me that he only likes this bike's foot rest. rest is crap. I asked him it bears same engine and same brand. but that illiterate chap was not convinced 
Sportster is looking ugly on Dream.
It suits on pridor. Not on CG Dream.
Yes. one sided sportster doent look cool.
