Ca. reg.s only cover the cat.s to 6/60k. I went to the flowmaster site but couldn't find any listing for contours. Any sugestions would be appreciated. Is this a job I can do myself or should I have a muff shop do the job?

Yeah...you could do it if you have a saws-all and a welder and can weld good. --Matt 2003 Sonic Blue SVT Cobra Coupe 2003 RedFire SVT Cobra Convertable 2005 Dark Toreador Red F150 XLT 4x4 2000 Black SVT Contour - Beater

My friend actually just bought one for his civic HB because it was extremely cheaper than OEM. 99 SVTC, T-Red, #652/2760-12.8.1998 Mother#@%@!* did I sound abstract? I hope it sounded more confusin than that!

As far as I know there are no alternatives to OEM manifolds with pre-cats. You have several options. 1. Pay for someone to put on new or used OEM manifolds. 2. Put on OEM manifolds yourself new or used. 3. Buy headers and do yourself or pay someone. 4. Gut your pre-cats yourself or have someone help you. 5. Buy some MIL eliminators and have the codes disappear. 1998.5 E1 SVT Contour #5482/6535

I got a P0421 code on my '96 about 4K miles ago, my mechanic suggested that I change the plugs/wires, which I did, and the code hasn't been back since. It had 92K on the original plugs/wires so I knew it was time to do that anyway. (Big Jim also confirmed this in a post he made here a while back). As best as I can determine, the extra HCs in the exhaust caused by worn plugs can cause an older cat to stop performing as effectively, but apparently the process is reversible, in that replacing the plugs, getting rid of the extra HCs, causes the cat to recover from it's loss of efficiency.
