Is 280-290rwhp is350 possible?
I've been searching around trying to find out what kind of dyno results people get modifying their IS350. I have seen a lot of results but nobody in the 275-290 range. I would think this is possible considering the baseline in the mid 260s.
Does anyone know if this has been done and what was added?

Note: he had a full exhaust system and an intake with it.

I'm shooting for 300whp this summer with the addition of ppe headers and mapecu3 (which will hopefully do what I expect). As I understand it, some folks were running an safc on their is350. I dont know what the results of that venture was but I'd bet dollars to doughnuts that the factory tuned it real conservative especially at wot. I bet there are more ponies in there than we think.

Could the headers be street legal if you used a midpipe with cats? Georgia only does a physical cat inspection and makes sure you're not throwing any codes. No actual smog test or anything.

So, bit of a pain to do each year... and if you strip a header bolt, or mess up an O2 sensor, or anything else that could happen during such you've got a non-trivial-cost repair in front of you too.
I could certainly see going through that trouble for something that adds 150 hp... 15? not so much.

You certainly could, but unlike say an intake, it's a non-trivial amount of labor to do it (ie 6-8 hours by a competent shop, probably longer for the typical guy in his driveway... then same amount of time to swap back again after you pass).
