What Exhaust systems are people using on thier Mazda 3 MPS latest Gen?
upgrade and retune of the factory ECU done, almost 10KW atw everywhere with as much as 12-3ish in places with no mechanical mods... Torque limiting removed for bucket loads of 1st gear to 4th gear fun! (much more than teh dyno sheet hints at)
Now for an Exhaust - Is there anything decent off the shelf avialble?
Interested to see people's thoughts on what works and what doens't?
