Power, but also sound for a 250

I understand the 250 isn't the most powerful car out there, but I am looking to do something to the engine not only for a small boost in performance, but also to be able to hear the engine a bit more. Would a cold air do it for me, or would I need to invest in a new exhaust?
Any links to parts would be appreciated.

I have fujita intake, PPE headers and JoeZ racing exhaust on my is250, it definitely sounds a lot better now. An intake is definitely a cheap start and they produce a good deal of noise up front at higher rpm's.
FWIW, intake headers and exhaust will net more than 20hp, but not too terribly much. If I recall JoeZ gives around ~12whp and PPE headers gained ~15whp on a 250 (?) and JoeZ or FSport intake gives 5whp. Not much tp gain with these cars as you probably know, but it's still fun to drive![Thumb Up](https://www.clublexus.com/forums/images/smilies/thumbsup.gif)
And here's a short rev clip of my setup:

The downside is all that stuff together, besides being illegal in all 50 states (cept the intake, which is only illegal in CA), also runs close to $3000 installed... which isn't much less then the price gap 250->350, which would've added 102 hp.

Intake + headers + Joe-Z full exhaust if you want the most power and a good (loud) sound.
Still wont do much because the IS250 isn't able to be tuned, but you'll get a slight power boost. Next best option is to get a 350 for the extra power, and slap on a good exhaust for the sound
