I've noticed sometimes (not always) I get a popping sound from the exhaust when Im downshifting from 2 to 3 usually coming off the freeway. Just wondering if I should worry about this? Or does anyone know what this would be?
Mods: turbo back exhaust, cat less up pipe and I have had it pro tuned.
I never noticed this until I did the last mod for the up pipe and pro tune but I never noticed this immediately. Like 3 - 4 months later
