Hello everyone! My name is Nick and I just bought a 2007 Mazda 3 5-Door GT. I am curious about how much more horsepower does a new exhast give? Secondly, are there other types of upgrades where it will improve the horsepower of the car. Curretly the engine puts out about 156 and i want it near 200. Thank you for your help.


(Sorry if this was already asked)

A turbo would put you well over 200. And you should really search before you post.
