Re: What's my cat. pipe size ???? (Mein Rotes Jetta)
No, they also have 60mm inlet/50mm outlet cats for use with the dual downpipe.
To find out whether your cat outlet is 50mm or 55mm, go out and crawl under your car with a piece of string. Measure how much of the string it takes to wrap around your cat outlet. If the pipe circumference is close to ~157mm, your cat outlet is 50mm. If pipe circumference is closer to ~173mm, your cat outlet is 55mm. Circumference= 2 x pi x radius http://****************.com/smile/emthup.gif
