Review on Walker Exhaust 31388: High-Quality Exhaust Pipe Flange Gasket for Superior Performance by Richard Carroll

Items I like, excellent quality, not flimsy at all, very durable materials. The only downside I could find is that my exhaust ID is exactly 2.5, that's a few tenths of an inch off, so they're going to limit an exhaust of this size a bit at 600hp. With 2.5 dual exhaust, I'm not worried about that, but if you're running a single exhaust or higher horsepower, it's worth considering.
