Test Pipe Fitment Question
I am looking into ecodetuning.com's 3" catless downpipe and I was curious if it is possible to replace the stock downpipe with this piece but still attach the stock exhaust at the end of the pipe.

A test pipe is a term used for a hollowpipe that eliminates the catalytic converter. It doesn't have a cat so it is used for testing purposes only, hence the name "test" pipe.
