Hello villian. Nice rides.
Quick question for you. Did you lose or gain horsepower with you flowmaster exhaust? I have heard that many people tend to lose HP with flowmaster. Or if they gain anything it is very small. Thanks

when installing the first 3" system with turndowns, I gained 12 hp over my old 2-1/2" system that also has flowmasters. As mentioned in the info, the new system with tailpipes only cost me .9 rwhp on a dyno, and added about 35 lbs of weight. I'm sure correct muffler selection is critical to this, but the car is much quieter at idle and cruise speeds, while being close to the same level of noise at WOT.
