New header for SC300, pretty good gains

mods, i'm not sure what the policy is about recommending a specific place to get a part so if this violates any rules please feel free to delete.

i'm in NO way affiliated with mazzuri super, i've been following the development of this header since it first started and now that it's available i think it is a worth while mod for those NA guys wanting more power without the boost.

It is intended for an is300 but i'm sure it'll work for the non-vvti guys. It makes the most power with a 3 inch exhaust as it added 39 tq and 29 hp to the wheels on a stock is300 auto.

i may stick with my vvti SC after this release.

the forums have more info on it, i'm just spreading the word.

they dont give nearly as much hp/tq as the new mazzuri header does. Also those headers also leak and sound tinny.

there is a dyno in the link, i don't want to hotlink it, but it's there and shows the gains. i'm not sure what the gains would be on non vvti but i'm sure they're comparable. also those gains are UNTUNED, so there's still more powerl eft to get with an intake, exhaust cam and SAFC.

Is300

On the website it says that the headers are for is300 Will they also work for the sc300?

well for us VVTI guys it should bolt up correctly no problem, more then likely we'll need to adapt the cat and rest of the exhaust to the new manifold, it may be too short.

i'm not sure about the non-vvti guys, i dont think they changed anything in that respect so it *should* bolt right up.

i think it may be too short to bolt up to the rest of the stock exhaust, then again it may just line right up!
