I could show you many more dyno's, but I don't want this to get way off topic. |
Go back and read my post again and because I think you missed the context of it. This is not a new thing you know. It's a pretty common understanding.
Side note: Thread in link list...
Stock from valve cover to oil pan
RBC manifold
11" intake with velocity stack/filter combo
Tri-Y long tube header
3" Thermal exhaust
Tuned with K-Pro on my shop's dyno
Hardly just a 3 inch exhaust thrown onto a 100% stock car.
