Custom Catback System

[Black Yaris]

For those of you who stated this above...
if you are going to buy an axle back then replace cat back with something bigger, how about you just give me that money for the cat back instead? you are still going to be bottle necked down to 1.5 at the axle back, to do it right you need to run AT LEAST 2 inch off the resinator ALL the way back to a muffler that has and intake of 2-2.5 inches, but all the axle backs for our car just bottle neck just as bad as the stock right down to 1.5inch pipe

i think they used the same-length piping on my custom job on the GTI.

when you crawl up under your Yaris , you will find that the exhaust is 1 piece starting from the header all the way back to the axle ................. Have fun :)

That fact is EXACTLY why you see nobody offering a catback system for this car.
