Rainbow Muffler in St. Petersburg. Taken all my cars there the last 2 yrs or so. Their located in between US19 and 275. Off 38th Ave. N. If your coming from Tampa. Take 275 S. get off the 38th Ave. N. exit, make a right and their on the corner at the first stop light you come to. They'll be on the right and a gas station will be on the left.
