Another Question...

You should have waited for the rest of the exhaust if you were getting the header because the header collector is 2.5" and if you're cat-back is smaller you're going to need to piece them together with a connector. It shouldn't pose any problem though in connecting at all, just would have been nicer to do it all at once. It definitely sounds different. Look in the "Exhaust sound clip links!" thread at the top of the "2.3L Tech" page and I have a clip in that thread. My exhaust setup is desribed in that thread.
