Not as a bolt on alone, especially shortyies, I wouldn't waste a single $1 on a shorty. Long tubes might give you about 10-15 HP if the rest of the exhaust is done right.

MPG won't really change any except maybe at really heavy throttle angle where the computer ignores the O2S and it will lean it out a hair but it will be hard to notice without other supporting modifications.


I am not causing global warming, I am just trying to hold off a impending Ice Age!
