90 GT Exhaust Question

I want to put a new exhaust on my 90 GT. I want the car to be street legal, noo off-road exhaust. From what I understand the X-pipe is going to be best with me, i think I'll definitally go with that. Here comes the stupid questions.... First do I replace the mufflers? Do you buy the X-pipe with new mufflers? Should I buy the X-Pipe and get a set of seperate flowmasters? Should I use the stock mufflers?

Thanks,
Al

Come on, SOmeone?

Why not just do it all at once? Not sure what you have for headers, cause you didn't mention them. If it were me, I would do it all at once. Headers, x-pipe, then a cat back of your choice.

Oh maybe I wasn't clear with my question. I want do do it all at once. I just don't know if when I buy the X-pipe does it come with mufflers? Or do must people use stock mufflers? Or should I buy muffler flowmaster mufflers seperatly?

it goes,headers->midpipe->catback...the xpipe is the midpipe and the mufflers are included in the catback. what hiflow was sayin is, get the x pipe if thats what you want, and there are dozens of cat back options to choose from...

Yeah, h/x-pipes are befire the mufflers and are a seperate pipe, then the mufflers follow in a catback set up.

If you want to stay street legal like you mentioned, then you have to get a catted h-pipe or x-pipe, and that's going to cost you about $400.
