Does anyone know how long my stock H-pipe is? or know where i can find how long it is?

I need to know this because I just bought some long tube headers because I'm planning on making my own H-pipe with cats and i dont feel like paying $369 for an H-pipe with cats that fits long tubes (i want to keep the car street legal and to pass OBDII regualtions).  I would also need to know the angles of the bendings in the tube. If anyone could please help me, it would be greatly appreciated.

Thanks!
