The exhaust flows pretty well. The car makes 574 rwhp with a 2.3 Whipple at 13psi on 91 octane. The mufflers are all magnaflow. The piping is all 2.5" stainless steel. I built the exhaust to keep the car quiet and reduce droning. It works fairly well. Very little drone and the volume is close to stock but with a much deeper tone. The intake can still be seen a bit. The coating on the intake is to help make the killer chiller more efficient. The bumper looks much better in person. I thought it looked a bit off in pics also. Then I saw one in person and it looks very clean and finished. The side reflectors are also shaved off.
NOW IT MAKES SENSE you did it for sound ./ drone more less then power, yeah im sure its quiet and wow yeah thats really good numbers for only 13psi on pump gas, but imagine the gaines on normal 15-20psi boost with 93 octane and long tubes and diffrent exaust hahaha holY HELL! lol
