Pipewerx back box

Here's a few pics of the custom exhaust, it seems to growl more than the janspeed if u know what I mean, I'm extremely happy with the whole job. Will put some better photos and vids on when it stops raining lol[album]10163[/album]

Looks great. Did they delete collector box and bolt to standard cats then?

I'm not to technical I'm afraid, but it's still the janspeed manifold and remember him mentioning sports cats, I'm going back next week to pick up the old back box will see what he says.
Also they used wider pipes (will get the measurements) and that has made a real improvement in performance
