Do you have to run mulfflers in Tucson AZ

 

Check with your local dmv laws.

 

If you live in the US, for the most part yes. There are noise restrictions. The usual is 100dB's at 100ft i think... SLP makes the Loud Mouth exhaust sysem that doesnt use a muffler, but just a resonator in the I pipe. Sounds very mean and flows very well. If you wanted a set up like that, check out SLPonline.com and look up loud mouth exhaust. You can get a good idea of what im talkin about and maybe fab yourself your very own LM for third gens!!!

 

That is funny. I live in Denver and have the sniff test every year. My car has not had a muffler snice I bought it 4 years ago. Just the cat and then pipes to the duel exits. It sounds good and passes with flying colors, so why spend the cash on a high $ muffler? Heck I think I even pick up a few hp with it off.

 

If you want a '******* CAMARO" its best not to use a mulffer. However; in most areas they are required.
