If you have a diesel, you don't need a cat as it's just a smoke test, and you need at least 1 box in the system - so your backbox will do.
If you want a full straight through, weld a straight pipe through a cut open box so it appears to the MOT tester you do have a box.
Yeah its a diesel (306) yeah ive an exhaust on the car atm with mid box and bb, but took it off the day as a few ones wanted to hear what it sounded like and it got me thinking about it, its just itd be handy if it would but if not the exhaust on it atm can be put on in about 20mins
