There's a lot i want to do to my 2006 mazda 6s (3.0L, VVT) and i want close to best as i can get. right now i have a k&n typhoon intake. ive been trying to do some research on my own before i go bumbing around asking questions. after i recieved the intake, im now interested in an exhaust. i think i found one
--- this is the Injen Exhaust System I found. I tried to narrow it down to a couple injen systems and i think i like this most. what are your opinions? good or bad? the next serious questions is what headers? im just starting to learn the kinds and brands of headers. I heard MSDS headers are good but what manufactuerer and so on?
