Flex section works great!

Customer service responded in a timely manner when I asked what length I needed to order to replace the worn out flex section in my 3inch ZZP downpipe. The product arrived quickly, was good quality, and works well.

Great product (3")

I was going crazy trying to find my exhaust leak until I learned that SLP headers just make that noise. (How they can sell noisy headers for $800 is a mystery to me.) I cut out the SLP flex joint, welded this in and the noise went away completely. Also, it end up at 3" ID in the middle, almost 1/8" larger than the SLP one.The bad is difficulty of installation. First, it can't be installed directly to the header collector - a short piece of pipe is needed. To weld all 3 layers requires careful multiple passes with a MIG (stainless wire, of course) or preferably TIG welding. ZZP did offer to TIG it for a reasonable rate, but that adds a lot of logistics and downtime to the installation. It seems to me such a joint could come pre-welded to itself, ready to burn onto standard pipe, but I've never seen such a product, so I can't fault ZZP.
