Review: Look no further - The fit was awful but that was my fault for ordering the wrong size. Make sure you double check that. I imagine if I had got the right size it would have been a piece of cake . I had huge gap welds in some spots and I was impressed with quality of the metal. It didn’t just melt away so definitely value for the money. Also they sound nice wasn’t an issue at all and the function as they should. Get the right size it will be an easy install.
Review: High flow cat - The product is great,looks like good quality made with great materials, and the price is amazing but wasn’t able to put on I ordered 2 but never got the other 1 so got a refund for the 1 I didn’t get and just got the plug and play. I would recommend to anyone that would want a high flow cat

### ⭐⭐⭐⭐ Pretty dang good for a cheep thing
*by M***L on April 30, 2026*

I put this on my 1998 Chevy s 10 with the 4.3 L engine with stock exhaust. It fit fine I just needed to go to the parts store and extend the converter a little bit to make up for the stock one. Other than that it was fine. I’ve been running it for the past month and my fuel efficiency is back and my power too!
