That's a nice motor and all that torque will probably break other things in the drivetrain (unless the owner has little tires). And if RichN tuned it, I'm sure it will purr like a kitten and then roar like a lion as you mash the loud pedal. I see that TTI recommends http://www.ttiexhaust.com/MoparClassics-Headers/Hemi6265/TTiHEMI625-218214.cos.htm for E-Body with coil overs. Do the headers in the dyno run video belong to the dyno shop? I ask because I see the exhaust temp bungs welded in and I wonder if they will hit the inner fenderwell shock tower area on passenger side once that bad boy is in the car.

I just ordered a custom set of TTI 2-1/4" primary tube with 4" collector with O2 sensor bungs and a V-Band flange instead of the 3-bolt collector flange. I was going to wait until after installing a Gerst K-Frame so I would only have to order those expensive TTI Headers once but decided to just go with my stock k-member for now so I can get my Hemi (https://youtu.be/95gZTspdzsg) installed and get on the street/strip this year. My current exhaust system uses 3" UltraFlows but as my hearing gets worse, I think I'll switch back to the FlowMasters.
