First off, I'm in Broomfield County, CO which requires that I do the IM240 test, which means I will need functional catalytic converters, air pump, and all that BS on my 94 GT. :cry: The guy I bought the car from did some kind of a hack job with the exhaust to include welding on some boxy-looking mufflers that I'm not even sure are for a car. They hang super low and scrape anything sticking up on the road. Generally, the car smells awful when it runs. I took it to my mechanic friend and when they brought it into the garage and ran it for a bit the entire shop filled up with strong NOx and fuel smell. He recommended replacing everything from the headers on back. I have a line on some BBK ceramic shorty headers and a Borla catback set of mufflers, but I was wondering about the midpipe. Should I just get newer high-flow cats and weld them onto the stock h-pipe or just get a new midpipe altogether? I was looking specifically at the BBK catted x-pipe, but they will add $420 to my budget. Also, I wonder if I'd really be saving money by retrofitting the old h-pipe. Pretty sure I know what the answer to this question is, but let's hear your opinions.
