Zorst Back To Standard And Fuel Through The Roof!

[lighty01]

hi all,

Ever since i changed my 3inch cat back exhaust back to standard (front pipe and dump is still 3inch) my fuel consumption has gone up. (i took it off so it would go down)

the only other thing i have on my car is a FMIC....

is that suppose to happen cause air is harder to get in and slower to get out?

if so, im puting my exhaust back in.

you will get better economy with a free flowing exaust. the engine does not need to make more power to push the air out.
