ImportEvolution.com legit

Hate to keep posting "is this site legit" questions, but im really paranoid about getting ript off because of what happend to me before. Anyway... Does anyone know if importevolution.com is a legit site? Im trying to purchase a catback because chicago has absolutely no shop that makes mufflers...well there is one and their overpriced for just press bending...other than that thats it....this shop in chinatown wants to charge me 540 and thats the cheapest in the city...Import evolution has the system for 460 and with shipping it will probably be like 500 so its a lot cheaper! Thanks guys!
