Emissions + Testpipe insert
I have a full 3" turbo back system with a fake cat. I also have an emissions test coming up.
My DP just slides into the fake cat and I use a clamp to keep it there. What I was thinking was to get an old cat, punch out the insides and make an insert that I can easily remove when the test is finished with.
I'm sure I've seen this on some site before but for the life of me I couldn't find it. Has anyone ever done this or seen it done or know where to buy a premade one?
