I am new to the header/exhaust scene and basically I want to know if this is a good deal. I also have a few other questions I hope can be answered.

https://www.scionlife.com/forums/viewtopic.php?t=216601

How does it sound?
How does it affect the gas mileage?
How does it affect the warranty?
Will any modifications to the computer or O2 sensors or anything else need to be done?

Please be nice because I am a noob here and I want everyone's opinion.

I drive my tC daily and most of the time I am at speeds of 60 - 75 mph. I don't want my gas mileage to suffer.

 

Raspy
Itll go down a little
Warranty is fine unless it throws a CEL, which it will, and you need to get an antifouler
Antifouler on the secondary

 

It will sound very loud and very raspy. Since the car is a 5speed, it will be terribly loud on the highway at 75mph

Gas mileage will suffer. You will be making more power and the engine will be running slightly richer.

The dealer will most likely deny any warranty claims since you are modifying a piece of the engine. Even though its not technically a piece of the engine, there are pieces in the header that do affect how the engine works.

Yes, you will need an antifouler to get rid of the 02 sensor.

I personally think you will be unhappy with the setup. Your best bet is to go on youtube and listen to some exhaust clips.

 

Thanks everyone for your replies. I have decided to NOT do the deal.

I am glad I can count on my fellow SL members.


THANKS!
