I must say, after a week of this setup (Catless DP w/ Muffler Delete) I hate it. Sure it sounds real nice when you get on it and you're having some fun, but for everyday use it's just too much. My cold starts sound like a diesel truck and it just attracts too much attention IMO. So I think I should ditch the muffler delete and go for a more conservative catback. I don't want quiet but I don't want ear deafening. I think a Q300 with my Tomei Catless DP will be a nice alternative. From what I've seen the Q300's are fairly quiet until you get on it, which is what I want. What do you guys think?
