With the flapper disabled they are close, I agree the performance one sounds better, but like $200 better, the difference is not worth the price of admission in my book. The beauty of stock is you can get pretty close with the flapper disabled, but if you don't like the noise or drone, you can put it back, performance exhaust you are out the money and stuck with the noise!
