I have done a good bit of mandrel cut and fit exhaust. I actually love the work. It is fun to put it all together to me. It is more work than paying someone else but it is how I want it when I am done. I probably have 20 different pieces in the S10 crossover pipes and downpipes. Everyone requires tweaking, but you get better and better at it. I can eyeball most cuts close enough to make it work now......maybe just a little grinding
Anyway, I understand the work, but I like it...
