gstraw Posted June 30, 2014 Share Posted June 30, 2014 Not scientific if course but I'm not surprised with the result. Reduced a restriction so my mpg is higher by around 4mpg!! Very impressive! Car also sounds great! Quote Link to comment Share on other sites More sharing options...
Will370z Posted July 1, 2014 Share Posted July 1, 2014 I found the opposite on my 350, I found my mpg plummeted, something to do with the noise and my heavy right foot I believe. Quote Link to comment Share on other sites More sharing options...
