All of you are not seeing the complete picture. This is something that has already been posted in this forum by other members and completely overlooked.

#1. RoxRocket says "The overall pipe diameter between both pipes is enough to feed a small block.

#2. Others have pointed out the same.

Here, Let me show you school children (DemonSVT) what I'm talking about.

Take your crush bent exhaust. 2 pipes at 2.25 inches. On crush bends only the inside of the pipe is actually crushed - And true mandrel bends lose diameter on the inside of the bend also - Just not as noticable. Say the the crush in the bend reduces pipe diameter to 2". That's a 1/4" in pipe deflection. So in the worst case scenario you have two full length 2" pipes considering the defelction. Do you realize the overall total exhaust cross size is 4"?

2.0 + 2.0 = 4.0 inches. The system has more than enough capacity - The factory system has one single 2.25 pipe and a 2" neckdown at the factory Y. Using basic mathematical calculations 4" cross section is a HELL of alot bigger than the factory 2.25". Losing power from backpressure? Where in this system could you get backpressure from? You effectively doubled your factory flow right off the bat running the system at it's worst point.

Crush vs Mandrel is a very old topic. In a single 2" pipe coming from the engine back this could be a critical point. But for this setup - Using mandrel bends would NOT make any benefit.

Geez - And it didn't take a genius to figure this out, just a brain that some people seem to forget they have.
