Custom Cat-Back exhaust Yaris TS

[CASTREX]

Yes, no, no and yes.

It will work on a sedan, the exhaust layout is the same.

It doesn't throw a cel. I still have the primary cat I just removed the secondary cat. My car should be able to pass emssions test.
The o2 sensor picks up it data from the primary cat, if you remove the cat after the sensor nothing will happen to the car.

No need for a spacer... only if you remove both cats.


Yes, there is a difference. The car picked up some power from 4ooorpm to the red line.

It's louder than stock... is not obnoxious or anything but if you do long comutes it might get anoying. A solution for this would be to use a different kind of muffler on the back. The sedan has more space than the hatchback.

You can go for a turbostyle muffler on the back like the dynomax superturbo... that should make it quite.

nice i might just do this and i already have the nitto turbo axle exhaust from garm

oh I see... I guess the nitto should be on the quite side.

One suggestion. If you are getting rid of the OE resonator, have it replaced by large resonator. To save a few buck I've seen people use a small glass pack. That will make your car loud. Mine is a 4" round 18" long Magnaflow and it helps a lot.

Also, for your car I would suggest a nice 2" mandrel bent pipe.

I went 2.25" since my car has slightly more displacement and to make up for the crushed sections of the pipe since I don't have a shop that do mandrel bents near me.

I really like some of the aftermarket axelbacks available for our car... I just can't stand the fact of paying $300 - $400 for one when you can have a full exhaust with good quality parts made for that money
