Picking up a Topspeed Pro-1 axle back soon for the meantime before dropping big bucks. I've sat in a 6mt with a Manzo(same thing) axle and it sounded really smooth for what it's worth. Any comment on these Taiwanese Ebay market sale exhausts?
Sport acc muffler installed today. I'm verry happy with the results. Nothing new; it sticks out more than stock as others have said but I think it's great under the AK V2 diffuser. It starts up with a much nicer growl than stock but then it's very subdued until you get on it - I see my gas mileage suffering until I get used to having it on. I'm still planning on adding RHFCs and custom piping in between

We've all heard it before but I uploaded a clip of the sport acc muffler.
The rest of the exhaust is still stock for now

It's honestly much more of a difference than I was expecting. This is a DD that gets used by the other half quite often, as well as for work-related trips so for me it's a nice compromise between a more aggressive sound while also not having to worry about drone. I don't love the stainless steel tips but they're fine.
You're right about it killing the MPGs, though. Just like how my battery life on a new phone is always awful.
