Yeah, I'm thinking I might knock a set up out of 4" mild steel just to work out where they would fit best and to make brackets etc..., then copy them in stainless once I'm happy with the look. I'm also thinking about having a joining flange at the front so I could fit a hotdog style muffler inside. That way there's no mufflers under the van, just the pipe from the extractors to the front of the sidepipe.
