Review on Walker Exhaust 52241 - High Performance Exhaust Pipe for Improved SEO by Arunprasath Corso

Definitely a quality part but the description doesn't say what it is: - Air gap double wall tube, there is a smaller tube inside the other separated by an air gap for certain thermal properties. The outer pipe OD is at least flared past the outlet flange, this is *not* a standard exhaust pipe size that will fit into another flared fitting. In my case the belt, stock front tube, flex and flanges in salt are long gone and have been replaced with a mix of direct welded and clamped parts. As a result, I was unpleasantly surprised when I cut the flange off the back of this piece to fit into a flexible clamp joint, and it was double walled with an atypical outside diameter - I was over the edge at that point too. Possibility of return/exchange. Again - definitely a quality part but be careful what you buy if you want to modify it for installation rather than bolting directly onto existing flanged parts on either side.
