& what has been your experience?

Just looking online there are some intriguing systems from Milltek, AWE, & I'm sure others (see YouTube link as example). Just curious if they're claim to boosted HP lives up... I know they sound awesome and are relatively nominal upgrades from a cost perspective...

Also, what would this do to the warranty &/or lease provisions??? I know in some instances mods are a "no, no"...

Pretty tempting...
