My 2011 Vitz

Yea man straight pipe is the way to go

just go 2.0-2.5 depending on your plans, delete both resonators and the cat if they will let you, in Cali you will HAVE to have a CA DOT approved hi flo cat though or youll be fined im sure. Just make sure since youre going straight pipe, that you put a nice muffler in the rear that doesnt restrict but that gives you a nicer deeper tone.

Yeah man I definitely want to keep the cat. I just want to make sure it sounds nice and has clearance haha. I'll definitely keep this in mind though!
