[QUOTE="xblitzkriegx, post: 15168820, member: 105608"] I think this shows more that the headers on that engine were larger than they needed to be in the first place. Considering the rpm and engine displacement, a 1 5/8" primary tube would've been fine. I bet you wouldn't have seen much of a bit with 1 1/2" primary tube header. Many people run too large a header and make similar mistakes on exhaust pipes as well. Case in point, hellcat engines make 700hp using 2 3/4" exhaust tubing. I bet it could make a little more with larger tubing but my point is, it already makes 700 thru "small" tubes. Any car guy using the engine in the video wouldn't think twice about 3" exhaust. Reality is that 2.5" would be just fine. [/QUOTE]
