The next big project i have in mind for my car is to get a full 2.25 exhaust system(first on the list to help start my car to get ready for my 3sgte) (spec pending on all the exhaust parts) And i was just wondering if running the car with bigger exhaust would increase MPG at all?

I was just thinking becuase of less back pressure in the system or something... This is not my area, so i figured i'd post on it:)

Thanks for your help

well people have told me it makes petrol worse but when I got my exhaust I'm pretty sure it stayed the same, its hard to say, if done right I doubt it will make a noticeable difference if the car uses more or less petrol.
