I am going to ordera 3" converter today from ebay but I was wondering three things 1) Go with magnaflow carsound or Catco ( not sure if they are the same but there is $25 difference)? 2) is there an O2 bung on the current converter? 3) what should the overall length of the converter be with the flanges welded on? It's for a 96 240 with a Hotshot header and Megan exhaust BTW. Yes I know I didn't search much but it would take longer than I have time for ( at work ) to look it all up. Any info I can get is great the faster I get it is better, thanks again and sorry for the noobie move with the search thing. ME=
