Hi,I have 2002 mustang V6 with complete dual exhaust system with x-pipe from "PYPES".This system is extemly loud inside the car and car is not running smooth.Before instalation was everything o.k.I just want dual exhaust sytem and I don't care if is x-pipe or y-pipe. Do you guys have any expirience with diferent system.My friend hi have flowmaster with y-pipe and mufflers50 delta ,this is perfekt system but this is not available for 2002 they have same system but 40 mufflers and they are probably really loud( but I don't know) please help me thanks Pavel ( bartospavel@yahoo.com)

 

In order to solve the problem with the sound you'll need a silencer. These things should cost you somewhere around 150 dollars.

The problem with the running could be that the exhaust was not properly installed. What I would do is have a flowmaster X-pipe installed instead of what you have now. Flowmaster is that much better even if it does cost more.
