Hey guys, I'm just curious if a slip on is ok to get, or should I go with a full exhaust? I just don't want to waste my money getting a slip-on if it really doesn't do much as far as adding power, only better sound. I am looking at the HMF sport series pipe. All feedback would be greatly appreciated! Thanks I was also looking at the HMF optimizer as well. Let me know your thoughts on this please.
