I own a BMW 2004 330ci,(E46)...The stage 1, easy to install, my son and I installed it in less than 20 minutes, the performance is definitely noticable. You get that deep roar when, punching it to pass or just speeding up. Noticed a slight rise in gas milage sense the install. Love the sound it makes when the ignition is turned off..(the release of vacuum). The price was very reasonable..
