Has anyone experienced this with your exhaust???

to replace the CATS you replace the whole H/X pipe unit.. the factory unit is an H pipe... you can dig up an OEM replacement H pipe I'm sure.. but if you're going to replace them go with a HI FLOW cat'ed pipe.. it'll have only two cats (as opposed to the factory 4) and they'll be designed to flow better then the stock setup.. yet still pass emissions. Though I bet you could land a factory pipe off ebay.. lots of people who dont get inspected will ditch them... I ditched mine, but I have to keep it, once I year I slap them back on to go to the inspection place... get my sticker and take them back off.. it's not HARD but time consuming.. I can afford to spend an afternoon doing it once a year... it's just a couple bolts that hold the pipe up.. it's flanged front and back.. the worst part is the bolts like to rust into place... but some WD40 and some elbow grease should get them off... or worst case a dremel.. cut them off and buy 8 new bolts fo 50 cents..
