Looking For Light Mods That Wont Void The Warrenties

[KvnChu]

I am looking to do some performance mods on my IS350 '07 that wont void any warrienties

Any suggestions?

Very few mods (that actually add any performance) exist for the IS350. Your warranty can't be voided by ANY aftermarket modification though unless the mod itself causes whatever failure you're trying to get fixed, that's federal law... (ie an aftermarket exhaust system has no impact on the warranty of your brakes for example).

If you don't care to break federal law by removing your catalytic converters there's really no mods worth the money (IMHO) to add power... the best 100% legal exhausts add maybe 5-7 horsepower... you could do a Joe Z intake and maybe pick up a similar amount on that end, and that's fairly inexpensive so might be worth it to you... and that's about it.

If you don't mind an illegal exhaust system a couple of those (LMS for example) can give you in the neighborhood of 15-20 hp for a bit north of $1000...

If you want to go faster without adding power you can always go with lighter wheels and tires.
