I just baught a 2002 gt and want to start off with a cold air intake. And exhaust but should I buy the whole cai or just the filter and how could I make it sound better for a reasonable price

 

There are numerous CAI's out there and some need a tune, some don't so decide what you want before you buy. I have an AEM that takes no tune. Nice aluminum intake and an open filter. Was on the car when I bought it.

Sound is a hard decision. Mine has 40 series Flowmasters....not my choice but not bad. Again, on the car before my owning it. Some drone plus on the Vert, things are a bit more noticeable. Try to find some local cars like yours and listen....most of the online sound tracks are off compared to real life. Check a good local shop for exhaust work. They can be reasonable at times.

 

CAI systems are pretty much a waste of money on the New Edges. Exhaust would be a good start.

 

That's correct for the most part. Get the K&N drop in replacement filter and the intake will breathe better. You might remove the air silencer (snorkel going into outer fender) as well.

As far as inexpensive exhaust goes... well I don't know what you are looking to spend. I removed the cats and put in a MAC off-road H pipe then threw on some weld in Flowmaster 40's. Sounded very aggressive on the 2V motor and I was always getting comments on it.

Then do something with the gears...

 

Cold air intakes def dont need a tune and they add zero performance gains, there just for show. Get a drop in filter and be done aftermarket tubes cant outflow stock
