Hey guys, recently purchased a Full Tomei exhaust with the Tomei y pipe and had a shop install it since I don’t really have any tool. Fitment seems good and everything but I do have a weird hissing sound mostly on deceleration. I thought that normally you only get the “hiss” with test pipes. My cats are stock with just a Tomei, is this normal?
