I know I shouldve gotten the IS350, but I always wanted a manual tranny and I guess it wasnt "cost effective" for them to make a manual tranny for the IS350. I am happy with my IS250 so far but I want someone to break it down for me and let me know what I can do to make my car faster! I've read posts on intakes and exhaust not doing much, is there anything else I can do? If it boggles down to nothing, I will still be happy. Happy Valentines Day, Thanks.

you can wait until someone boosts the 250. until then you can buy a ~1hp intake and filter and a ~3hp axel back exhaust. you could get the megan racing headers, that would probably add the most HP as the stock ones are restrictive to a degree, and they have that pesky cat on there ![Wink](https://www.clublexus.com/forums/images/smilies/wink.gif)
borla still claims they are reworking an exhaust for the IS but i'm not sure of it. JIC is supposed to be making a cat back exhaust as well.

thanks for the responses, like I said I'm still happy with the car. I would be that much happier if I can make my baby run faster. Oh well, slower cars give more time for chicks to check us out. LOL

according to some dynos the joe z tube ($110) provides 7rwhp, and the Tanabe (~$575) provides 4 rwhp. Therefore, for $685 you can achieve an additional 15 or so horsepower to the crank, resulting in nearly 220 horsepower. Not bad.

Lol I hear ya man, however, 7rwhp from an intake is a hell of lot more believable than 19. Also, I don't think Tanabe would "lie" about 4rwhp, so i think some credibility should be given to those claims, as opposed to the fujita claim.
