are 355 and 348 test pipes the same?
If I recall, there are 2 types of either 348 or 355 test pipes, depending on which you comp you have. (What is it a 2.7 and 5.2? I dont remember at this time) This * may * cause a difference, since the sensor * may * be different, I am not sure. So early 348 pipes would be a no go, at least how I figure it. Edit: It was 355s, and from our site sponsor: http://www.andale.com/store?sid=173907&cid=10660952&mode=1&catId=1257196&pnum=1&tpages=null&psize=10&lid=&storeLayout=techno&storeTheme=techno_red&view=CAT_HOME&newStore=null&parentCatId=
