Exhaust dimensions - Toyota Yaris Forums

I have looked everywhere for the 2014 stock exhaust inlet dimensions and I cannot find them. I plan to upgrade to magnaflow's street cat-back which has a 2.25' inlet. I am also trug to figure out what amount of gains I am looking at with this system?

From memory the stock inner diameter is 2" from the header to the reasonator, then it narrows to 1.8 or so inches. The 2.25" cat back will definitely give an improvement(throttle response, sound,looks), power wise its a toss up.
