Reviews on my current Mods.
Joez Direct Flow Intake: A little gain, but it's definitely louder than the stock IS300 intake. Could hear air sucking sound which is one good thing about it. :D
Blitz Drop In Air Filter: Improves third gear quite well. I could feel it that's the thing.
HKS hiper silent catback exhaust: Gotta luv it.. the sound level is just a bit louder than the stock exhaust. B) And there are definitely some gain in hp, with better throttle response.
King Spring 30mm Drop: Too soft.. but it's good for a comfy ride. If u're getting one of this, i recommend u not too. Coz if u hav 4 passengers on the car, the car would be too low and u hav to drive too careful.
Any questions r welcome
PS - Applies to 01 + Lexus IS300 Only...any questions ask me....
