hey guys I'm in the process of picking up a 04 G sedan. hopefully i should be getting it by end of the month. I'm new to the nissans and infinitis so alot of help will be needed. 1st question. if i install coupe midpipe and test pipe w/stock muffler would i get a better sound on my exhaust (somewhat louder)? 2nd question. if i install coupe springs or 350z springs how much does it lower??
thanks guys
