Hey there. This is an honest question, I am not suggesting anything negative about using R6 pipes, but I have been curious:
What is the advantage of using these with the pipes partly crushed restricting flow some (maybe not significantly), over cutting the cat of the stock headers, then welding a reducer on and sliding on your favorite can?
I did this with a Delkevic DS70 (Marthy style). If I were to remove my stock but header, use yours with my current can, would there be any performance difference do you think?
