I feel that these mufflers are like a placebo, they make you think your car is faster. I dont think there are too many people out there that call tell a 3-7whp gain in a 400+hp car.
Thats absolutely true. But its quite noticeable that the revs are much more free mid-high end as you stretch. This may or may not equal power but its a good butt dyno for at least 3-5hp at the very most.
