Matt,
I think you did a big mistake not getting the filter off me, you have atleast wasted $50, also the TRD FIlter is no longer the best for the IS200...Tom's has just released a new filter and it has a far better air flow compare to the TRD, plus it will be cheaper! For 10-15 more kw I would prefer you to get a Trust Intake System and a Oval Shaped Muffler...That will garantee you a 15rwkw (20kw) with S-AFC II Tuned...As for the TRD Grille, I m doing a groupbuy on it so I m sure you can also save alot on that!
Keith Have to correct you, TRD did not tuned the Modellista IS200 (Quadlitat) It was only performance mag thought... ;)
Matt I have a great knowledge on the IS200/300 so if you ever need any help, either questions or parts let me know and I will do my best to help, welcome to our site and hope you will find it useful!
Matt :D
