I never had my X-pipe installed with the stock mufflers so can't really compare it. Like people say on here sometimes, it's your car so as long as you like it. Here is a video of my exhaust, poor quality.
It sounds pretty good with the flowmasters that are already on there. I don't know what kind they are tho. They're just really rusty and crappy so I want to get new ones. I don't want it to be too loud or crappy but I don't want it to be restrictive either.
