Hellion twins install question

[dennisn]

Supposed to pick up a 16 next week and plan on installing twins. Tried searching for install info with no luck. Any links anyone could share I'd appreciate.

It's a 'tight' fit. Make sure the exhaust does not hit or rattle on the suspension or it will trigger the knock sensors.
I also HIGHLY recommend relocating the O2 sensors post turbo.

Because the 02 sensors don't work correctly pre turbo
