Shorty headers with Magna flow cats/X-pipe

Hey! I have a question. I have flowmasters on my car now, Would an X-pipe change the sound at all, and would their be any increase in power? also does any body have shorty or equal length headers installed on their 05 gt? I am just curious how they sound. My plan is to get shorty/equal length headers, Magnaflow high flow cats and X-pipe or I might keep the H-pipe, dont know yet. Thats about all I want to do to the exhaust but I do plan on getting a throttle body and a K&N aircharger kit, and later I will get it tuned. To me this seems like a good package that should produce some decent Hp. Does anybody have any sugestions? I apperciate any input I only know how to work on F-16's.

your shorty headers are about a waste of money. the stock manifolds flow excellent. if you are going to upgrade to headers, go long tube for the bigger gains. the shortys dont produce enough power to justify the purchase. $300-400 for 1-2 hp is not a good equation in my book.

That is what I have been hearing, thanks, I might just wait to do Long tube Headers now.
