Installed this when I upgraded to the TU Hybrid T3/T4 TrannyBuster turbo. Installation of the turbo was a little tight against the firewall and took a little positioning but I was able to mount it without modding anything. Puts the outlet of the turbo in a nice spot to run down to my FMIC without weird bends. From underneath and behind, I had easy access to all 4 nuts on the turbo flange. Awesome product!!
