We recently received this story about an exhaust system gone wrong. While significant money was spent creating the magnificent drive train, the exhaust was so badly designed as to cause Kevin Crocie of Colvin Automotive to wonder if the engine was damaged. After all, to have the World Products 427cid, 495hp engine only generate 258 horsepower at the rear tires, something had to be really wrong.
As Crocie ultimately determined, the exhaust system was the culprit – and was easily corrected through proper fitment. Documented here by one of Flowmaster’s technical experts, Jeff Thomas, who recently discussed the scenario with Crocie, the correction was miraculous – and cemented the fact that you can select the wrong exhaust products for your vehicle with disastrous results. This worst case scenario is a perfect example of – exhaust design gone wrong!
