The Yaris has a horrendously restrictive exhaust. Hell, just swapping the muffler (not the exhaust, just the muffler) with a Tanabe Axel-Back is freeing around 3 WHP for most drivers according to the dynos. The Megan Header hasn't been dyno graphed yet, but they're predicting a 6-9 WHP gain. Considering how bad our exhaust is, I just about believe it. If anything, it's a cheap mod that should give the car a little tone.
