Hey guys, im new to the car business.
i drive honda civic 2004, shalimar rose color.
Previously it used to be a powerhorse.. but now it just slacks like a sloth..
i drive it on cng... i have done everthing
changed oil, air filter and got my car tuned.. still performance is very low.
i was wondering if any of you guys.. expert at civics.. help me out on this performance issue..
Also im thinking about doing slight modification to my ride.
1. exhaust and piping
2. plugs (which ones should i get)
3. air intake
now as im new to this business... i have absolutely no idea where to get it done from and how much will it cost.. im afraid i might get ripped off by the rascals 
so if anyone can guide me through this, il be very obliged...
id like to know any good mechanic who can do all these modifications and the crude sum of money it will cost. (in pindi or islamabad)
p.s im using my bros account here, as the new account i made didnt have the privilege to create a new thread
