Tuned or Nontuned Pipe?

[ohmygahitscoby]

I've heard that getting a tuned pipe improves your car a lot. So I was wondering if my pipe was tuned or not. How can I tell if it is on not?

if its not the old can type muffler that came with an RS4 back in the day its a tuned pipe.all pipes(not can mufflers)are "tuned" its just a catchphrase to help them sell.there are certain adributes to a pipe that effect different things slope,length,stinger and abunch of other complicated stuff play a part in how the pipe performs.but for the most part just about all nitros come stock with someform of a tuned pipe nowdays.
