Well, I pulled off the ebay header and put the stock back on, but left the catback. After comparing the testpipe that came with the header and the cat forever, I realized that flange on the testpipe was about 10 degrees total off from the stock unit, and that was what was causing most of my problems. Now im saving up for a DC Header, but I also have to register my Legend and pay for NALM so im a little broke..
Also, since this car is in nice running and driving condition right now, I started another project

Just added a big update to it today if you haven't seen it. Its a turbo crx build.
#8 and #9. Yes really. CRX projects.
