I purchased a 3" cat back recently for my 96 Tsi and after inspecting the horrendous condition of my down pipe and cat I decided to just get a 3" downpipe, obviously with no cat. I live in PA, and the place I go for inspection does not do a visual emissions test. I planned on just keeping the old dp for testing, but after doing some research I don't even know if that's necessary. Assuming I use an O2 sensor spacer to avoid a CEL, does anyone from PA know what else is scanned for emission testing? I know I'm allowed to have 3 or 4(can't remember which) I/M sensors read not ready. I'm not sure what other data is read, if any, by the state emission computer.
Interesting side note: the EPA has listed 96 and 97 TSis (but not gst/gsx) as having problems with the ecu and I/M readiness testing, and that they should be tested without regards to readiness, but I could not get PA to recognize this for my 97 Tsi last year.
