The only point I was trying to make is that a good crush bend exhaust can , even in 1 instance, be superior to a stock exhaust. The rest were just performance results from 2 of my cars. These results are not to be compared just facts of performance. I was not trying to compare a ford to a nissan that would be ridiculous! DemonSVT put it out there that he was willing to bet that a 2.5" crush bent system would not increase performance over a stock svt exhaust and he was proved wrong. He posed the challenge of proof and it was met by another member. I look forward to DemonSVT's reply on this subject.
