X pipe H pipe or side by side

Going through my exhaust install now. Bought a Pypes set up and its not a bolt in job like they say it is. Having a local mandrel bending spot install and do the head pipes. After calling Pypes and talking to them about their "system" I'm having the local shop make up custom legs for the Pypes X pipe. Could have done side by side but already bought the X pipe system so I wanted to use it.
