Review on 🚀 Enhance Your Engine Performance with Polished Stainless Bellowed Up Pipes Kit for 1999.5-2003 Ford 7.3L Powerstroke Diesel 7.3 by David May

I have no complaints about these tubes. They went ahead and sealed as expected and although they haven't had a lot of time or miles on them so far everything is looking good. Welds were good. The material was a bit flimsy and the shape was a bit rough, but that's okay. There are many whistles sold under different brands on the market and I can only assume that MANY (most?) of them are about the same level of quality as these at a much higher price. You'll probably need to upgrade to something like the US made RiffRaff whistles, which are significantly better in my opinion, but also cost $450. In any case, you must understand that you are taking risks. Replacing the upper pipes with 7.3 is a very tedious and time-consuming job. I'm very happy with these tubes for the money but I have my fingers crossed that they last a long time.
