Hey guys, I am planning to mod my IS 350 FSPORT. Do you think it's worth it to put the F Sport Intake System + Ark Grip. I've heard that the F Sport Intake System does not really adds much to the sound or performance. Please let me know if this is true to see if I should buy them both or just the Ark Grip Cat-Back Exhaust.

 

Full CAI's offer some gains but nothing to make you go wow

Now if you're after a better sound, Ark exhaust will make any intake sound nonexistent
