Hey guys, im running a MAC o/r Xpipe on my 00' GT 5spd. After bolting it on it took almost a month for the check engine light to come on. I had it checked out of course its reading that the two back cats are not working. Well ive seen a bunch of MIL Eliminators some brand name and some off of Ebay. I was wondering if spending $20 for splice-in MIL's was better than buying $60 plug-in ones. I dont know how hard it would be splice them in either because I cant just take the xpipe off again. Well i could but it would be a lot of work. Anyways if anyone has any suggestions on good MIL's for cheap then please let me know. Thanks.
