amc hemi swap

Awesome(!) and congratulations!! She sounds good! Was that the first start up? Did you have to create the initial tune, or did you have a tune already? Please tell us more about the exhaust.

I got a 2.5" TTI kit, way back when I first got my 6.1. Built it with other, straight through mufflers. Since then, I had the engine bored/stroked to 393 but more importantly, I'm going to build it now with a Hellcrate engine. I've had my concerns that the exhaust may not be big enough. Stock Hellcat has 2.75 exhaust. What all brought you to the conclusion you needed to go bigger?
