It sounds nice, but I personally don't care for the looks of the slender pipe with a big wart muffler (although it looks like you did a good job on the chop).
How is your epoxy floor holding up? Mine started flaking in places after only one year!
Do you have PPG products in the States..? If you want an epoxy floor that will last for 10 years or more, try cleaning the bare concrete with a hydrochloric acid and water mix, this will etch the concrete and clean off all the contaminants. If you have PPG try and get an epoxy product they have called "Amerlock", this is the best industrial epoxy for floors you can buy,i have done thousands and thousands of square metres of flooring with this product. Most of the floors we do are high traffic floors and have semi trailers and forklifts {bloody big ones} driving on it all day and it holds up to that extremely well. In a home shop set up it will be extremely resilient and last for years.
Always wear protective gear and mask {2 pac mask} when using these products.....
