Is it legal to remove your mufflers?

[95GTS]

Here in MO it's illegal to not have mufflers. Shoot you're even supposed to have tailpipes here. The exhaust must exit out the rear of the vehicle. But most inspection places never notice because they never look so you can very easily get away with it. On my 96 stang I cut off the mufflers and tailpipes and welded on turndowns that dumped in front of the axle. Sounded really good and was not that loud. You'd be amazed how much sound those 6 stock cats soak up. You could hear it at an idle but it just sounded like it had a good catback on it. I had alot of 4.6 owners stop me to see what exhaust set up I had. It REALLY sounded sweet at WOT. After that tons of stangs around here started doing it. I did it on mine because a buddy of mine cut off the tails on his 5.0 and it sounded good. I just went a step farther and cut the mufflers off, too. I've got dumps on my exhaust on the L, too. The inspection guys never even noticed.
