Josh's GR Corolla Gets A Magnaflow Exhaust + How To: Transmission & Differential Fluids

[@breaks_n_stuff4049]

Oil yes, trans and dif changes after break in is overkill

[@murk4545]

I’ve heard the diff oil gets really sludgey 3k miles in but idk yet. I’ll see when I change it after break in

[@mr2marc]

after 621 miles (1000km), the oil was still clean, but the diff and transfer case was suppppper sludgey. trans is fine and i'm gonna wait for 3k (5k km)

How long before this burn 🔥 up spontaneously?

Also what floor lift is that? Its pretty neat

[@teamturner4300]

Its a Bendpak from about 10 years ago. I'm not sure of the exact model but I was told it is discontinued

[@yuyu-san]

Has MagnaFlow fixed the rattle issue that was plaguing these systems on release?

[@teamturner4300]

We haven't heard any rattling as of yet. 😊

How's the drone on the highway at about 80 mph?

[@teamturner4300]

I would say it's a 5/10. It's definitely audible and louder than stock, but it's not unbearable.
