Anyone have or know of a diagram that shows the setup of the stock exhaust setup on an IS350? Im gussing since it is a v-6 it would have two headers, maybe 2 resonaters, 2 or hopefully not more than 2 catalytic converters, then ive seen the back end, the Y-pipe into the dual mufflers. Thanks for the help in advance fellers. Ooh rah.

All you have to do is stick your head down and look. 2 headers each with an attached cat. Mid pipe with two secondary cat, one resonator and then the y pipe exhaust.

Although I have an AWD...
but the whole setup should be similar to the rwd's
so here you go

^^COOOO, thanks for that pic. Umm these CATS must be tiny, there should be 2 in this picture and 2 stuck on the headers, correct? Thanks again.

So this megan exhaust is probably illegal correct?

This is a cheap price, it looks like it replaces exactly whats in your picture, right?

Which part is the midpipe, I always think the mid pipe is right after the headers or the downpipe on a turbo car.

Illegal? Well, it really depends where you live. Here in SC the cops could care less.

That Megan exhaust link you posted is only for the exhaust...trust me, I looked into it. LOL!

The midpipe is from the header back to pass the cats and the resonator....right before the split into the two exhaust pipes leading to the mufflers.

Removing factory cats is illegal in all 50 US states... only difference is your chances of being caught at it is really low in states without inspections.

Its only illegal if you get caught, right? Lol! I hope SC doesn't adopt the NC inspection process any time soon.

Reviving an old thread. Could someone label which parts are which in the picture? Is the silver cylinder in the middle the resonator?

Yup... and the two big ones at the back are mufflers... the two smaller ones near the front are the secondary cats.

Not shown are the primary cats, which are built into the exhaust manifolds.

haha ~ i always see you explaining this concept in multiple threads
