Review on Walker 41723 Exhaust Pipe Adapter by Christopher Kumar

I used two of these in a custom exhaust I made for a race car. I like this guy when I want two or three degrees of angle adjustment for my final pipe alignment. But only a few degrees! Use some Permatex and try not to use them for double bending and you'll be fine. Mine are well and tightly sealed in very, very vibrating and very hot spots next to the headers on the V8. The only potential downside is that they're bulky, so they're better suited to spots like the engine bay or around the rear axle where you have space. For something near the bottom of the car in the middle, I use a band clamp instead.
