Cheap Exhaust Repair for Generic Pipe Replacement in GTA?

I have a 2001 Nissan Sentra needing a new Front Pipe (between engine and catalytic converter) replaced. I was wondering if anyone knows of any inexpensive exhaust repair places in the Toronto area that might use Generic, economy exhaust pipes? I looked at some places that used Walker or Bosal exhaust pipes and the price for the pipe itself is really expensive so was looking for a Generic, economy, OEM style.

Thanks.
