New NISMO exhaust MPG??
i just put this exhaust in and my average MPG went up to upper 20's for about 4 days.
now its back down to low 20's with SAME driving patterns and miles.
i have a K&N drop in filter before and after.
anyone know whats causing this reverting to low MPG's???
thankx!
i posted in this forum because i wanted to get the most opinions and wasnt sure what one it would go in
