So... Anybody switched their overhead/front pipe? I'm wanting to add bolt ones before getting a tune. @
ft86speedfactory has given me a quote for an Invidia catless frot pipe and Perrin overhead pipe for a great price, but I wanted to run it through my fellow brz/frs owners for opinions! I doubt I'll switch my intake, but I may switch the filter with a drop in. @
Dynotronics1 any gains on bolt on + tune that to can speak of?
