K&N Typoon Intake 2- my review

[Nutsid]

There really isn't a whole lot you can do intake wise from the after market that does any real increase in power, and those that do generally lower the mid range and add 1 to 2 horsepower up top. From everything I've read, the exhaust systems are essentially the same. Basically the only real reason people change them is for sound purposes. It is much nicer to actually be able to hear my exhaust now.

Having said that, you can add horsepower by doing custom intakes and exhausts - making them far more race oriented, but you'd still need a good tune as with any modification.
