Full exhaust System for NA yaris

[harveyjai]

Hi guys,

I just wanna know what would be the best combination of doing a full exhaust system for a NA yaris.

Atm, i have a bolt on muffler. I have read post saying Headers might not make too much difference. Also some of my mates told me to modify the cat or something.

What do u think is the best combination piping for a NA yaris? I wanna get the most out of my NA yaris...

I don't mine custom the whole thing, i just need some ideas.

Cheers,


Harvey
