Such an awesome product. I bought a few different sizes, which have enables me to start building a custom stainless system for my 4wd. Exhaust building has always been a love/hate relationship, mainly because of the fiddly mock up procedures. The tacking bands take out all the hassle, especially as you can align the pipes to where they need to be without actually having to tack them to sit in place first. A Win Win as far as I'm concerned!
