this maybe a dumb post but im new to the forums please help me out
i just got an 07 is 250 and im debating installing a
injen intake its gonna cost about 250 installed
is that worth it and how much horsepower boost am i looking at
is it gonna make a difference thati can feel in the performance
and i am debating what exhaust to put on
i want something quite on the inside and still have a little rumble on the outside
i was thinking about hte hks hi power exhaust
would that work for me?
if so how much is the hp boost and how much is it installed
thanks for all the help

I honestly doubt that you will get any noticeable performance boost, and alot of people here have lost a bit of low end power with the intake, about the only thing that it really does is make more noise.

because i feel like theres nothing there

I'd take the NA 4GR over the NA 2JZ any day for a lot of reasons, not the least of which is better gas mileage.

I hate to say it, but basically you made the wrong choice. The 250 performance aftermarket is tiny, and not likely to get a lot bigger any time soon because there is a factory option for a lot more power. This will only get worse when the IS-F is released, because the IS-F will be the solution for 350 owners who want significantly more.

Mind if I ask what you were driving previous to the IS250?
