Hey guys just curious about this down pipe for my 2025 mk5 Supra This this work ok without a tune ? Any problems with over boosting ? Any temperature problems ? Any issues or damage to motor down the road staying catless without a tune ? Any information is great thanks

Looking at Valvetronic or FI exhaust? What do you guys recommend and why? Also open to other options, i just really like the idea of being able to be close and open valves ! Thank you !

hey my stock valves have been acting weird lately they dont want to close no more. Once i start the car they open just on normal mode and they do not want to close and when i turn it off they close. I dont know if i shoulf buy a new actuator or what to do because it works just not how its supposed to. Has anybody had this problem before??
