I have a 99 civic dx hatch and have put up a few posts concerning headers and catalytic converters. As all my fellow hatch or dx owners know, the catalytic converter is built into the header for our engine (d16y7). If you replace the header with an aftermarket one, you lose the catalytic converter which will mean that you would not be CARB legal. I have been searching for a bolt-on catalytic converter for my car because I really wanted to get an aftermarket header. I think I may have found a solution: I found that Ractive (Toucan Industries) makes a bolt-on catalytic converter for hatchbacks (or at least that's what the website says). I'll try to see if I can confirm that it bolts-on directly (no cutting or welding or modifications). I was just wondering if anyone else has any info or can confirm any of this for me. Any help would be greatly appreciated!
