Magnaflow Catback with Super 44s welded. Help
 

Hello guys, I currently have the following setup

Mac Longtube Headers
Mac o/r X pipe
Welded in Flowmaster Super 44s on the factory Magnaflow Catback (04 Saleen model)

Why is it that my car sounds very quiet when compared to other Mustangs with the same setup but maybe not with the Flowmasters welded onto Magnaflow pipes? I have noticed that the tips of the tailpipes are skinny and long and go into the chrome tips and wonder if this has anything to do with it? Will shortening the length of the pipes and adding longer chrome tips help?
