Spintech
i have the spintech crossflow muffler and i like it alot. it has a old school muscle car sound. if your gonna run duals with an x pipe i would do 2.5" tubing. it makes it easier to work with and easier to tuck under the car. i would use the spintech pro-street mufflers. they have a small case and will fit under the car or behind the axle.
they are on the louder side of sounding good. they have a very unique sound that no other muffler makes. like i said it kinda has a 60's muscle car sound to them. the pro-streets are the best performing in the street muffler category. lots of guys with gtos run them. do you have an lt1 or ls1?
ok. you will like the sound of them. i like mine. but i would go with the pro-streets in a dual setup. they will be loud but i don't think too loud. plus everything sounds better on lt1's anway. 
the only thing i don't like about the sportsman crossflow is that its a little too quiet for my taste.
