I have a 06 R6 and I'm thinking of cutting the catalytic converter and replacing it with a pipe so I can open up my exhaust system or just purchasing a full exhaust. Is it even worth the dollar to buy a full aftermarket exhaust comparing to replacing the catalytic with a straight thru pipe and just throwing in a PC3? There's a company called MJS performance that cuts the catalytic convereter and replaces it with a straight thru and they said that it's almost the same HP gain if you purchase a complete aftermarket exhaust. What are your input on this? http://shop.mjsperformance.com/product.sc?productId=4&categoryId=3 I was thinking of doing this.
