I could tell the performance gains right away, went on easily and sounds great.
Short, cheap, perfect

I needed some cats for a mid pipe to pass emissions. These were very short and cheap, which were the two things I needed. You will not find cats any cheaper than these

This 3" universal cat. was perfect for my custom downpipe. It arrived quickly, right to my door. I wasn't sure about the quality, because of the low cost, but had a big smile when I open the box. Thanks.
