Wooo had my 3.5" catback system fitted today, has a 4" dump tip on it, was done at exhaust innovations, sounds awesome! Also had a BluPower Air Induction fitted, got exactly what I wanted out of them both, more turbo spool sound and breathing noise, has a nice note to the exhaust, not overly loud or droney, looks beasty with a big ass pipe, more response and definitely more power. Love it :ugotmail:
