The custom/aftermarket exhaust thread! [Pics + Videos]

[frownonfun]

so uh... i thought i was following all this exhaust stuff but now after reading this thread i'm a little unsure. if i want to replace my exhaust from the header back what parts do i need exactly? and is that going to be really loud? would it be worth the trouble from a performance standpoint? would i be better off just replacing cat back?

Well, personally I think it's worth the money. You can't have an efficient engine if your intake and/or exhaust is too restrictive (which is what the Yaris was cursed with out of the factory). If you wanted to replace your exhaust, I'd start with the axle-back so that you can find which kind of sound you like. Then you have the option of either going with the Nitto midpipe (available from microimageonline.com) or custom-fabricating your own midpipe (warning: the Nitto midpipe does not have any catalytic converters; they're just resonators). And you know, I would recommend replacing the header. The stock design is rather convoluted and doesn't lend itself well to a good exhaust flow. For this you have many options: TRD (expensive as all hell), Megan, DC, Thunder, DME, or, again, custom make your own. If you plan on doing more performance modifications to your car, a good exhaust system is pretty much invaluable. Hope that answered your question well enough :D

Lol, yeah I was going through some threads I wrote in a while back and I saw that no one had replied to you yet. I hate it when people don't answer my questions, so this is my way of working with karma
But yeah, the most amount of play you'll have is with the headers. Some improve the power more at the lower end of the rpm band, some at the middle, some at the top. The DME header is best, imo, for just spirited around-town driving. It's pricier than most, but not by much.
Cheers! Always eager to help out fellow Yaris owners - especially ones that like the new iQ (I'm buying that as soon as the first-year bugs are out )

Hey is that the only midpipe you can find. And why is it so expensive? Is there anything cheaper that you know of?
