Diy exhaust

[Janis]

So my friend owns his metalworks business and has all the welders pipe benders etc but he mostly works on farm equipment tractors loaders buckets etc. Ot him or me ever made exhaust system so i woud love to try and make one.
Plan is to use mild steel 2.5 inch from turbo.dummy cat and cheap back box.and do it on budget.any tips?what backbox shoud i use?does it matters much as long as its 2.5 inch?
Any help woud be appreciated.
Thanks

I'd take off the original one..from the std clamp below the cat .....bend a new one up as a direct copy, missing out the two intermediate boxes and buy in a back box that is just a tad smaller than the std one.....make all the hangers match and it only takes abuot an hr to swap pipes if you need to...but in Ireland no one will care
