Just bought a used 2003 coupe! love the car. I'm newbie to the forum.
Does anybody know if adding aftermarket cat back exhaust voids your warranty? And does anybody have any dyno specs. on cat-back's for the G35 Auto.

I'm thinking of installing the Borla system, I'm looking for a few more ponies without it being to loud! Like to hear from anybody who has done an exhaust mod. and if they think it was money well spent, please include brand and how you like to sound and performance.

A cat-back exhaust will not void your warranty.

The consensus seems to be that the Fujitsubo exhaust is closest to the stock exhaust, in terms of volume and tone.

 

i heard a fujitsubo exhuast yesterday on a 6mt and it sounds pretty good but u can also check out injen.com because they have a clip of a G w/ their exhaust.
