Dual Exhaust help
 

I am not sure if this is the right section.. I am looking to put dual exhausts on my 2006 v6...
I apologize if I am getting the parts/terms incorrect..
I currently have the 2 GT take off mufflers and the X-Pipe... I just need the driverside pipe that goes from the catalytic converter to the Muffler...
I assume I can use the passenger side pipe still..
does anyone know a good shop in Ottawa or around Ottawa that I can get this pipe from and it won't cost me an arm and a leg?
I can get someone to install the exhaust for me.. just need this pipe.

thank you
