Ok, So i read the Exhaust FAQ and Header FAQ and i stil... - 4/14/2008 4:31:19 PM    tarheels131   Posts: 32 Joined: 2/7/2008 Status: offline     Ok.. so i bought my car off an incredibly stupid kid in ohio who had shops do a ton of work on it, and doesn't know anything of what was done... so since i bought it i've been finding out more and more what it has.. but i've hit a bump in the road..  When i bought it he did manage to remember to tell me he just put a catback on it.  So i put it up on the ramps today to look at the Catalytic Converter because i'm replacing the header and possibly the catalytic converter.. and i noticed a few things.. first off it's rusted to h*ll on the cat.. second, the cover over the cat literally had rusted off almost entirely..  It was hanging on by threads so i ripped it off (it was making a really annoying rattling sound when i drive)..  Soo how can i tell if the Cat is stock or aftermarket???     I was planning on either getting the: Kamikaze 4-2-1 Two Piece Ceramic Header OR Megan Racing 4-2-1 Header.. (Do they sell that as two piece?) From my research on here, i've found the 2 piece will be easier to install and ceramic will keep the engine bay cooler.. and correct me if i'm wrong.. but i need not only the catBACK but also an aftermarket CAT to help with emmissions tests and pollution?  With this being said.. what would you guys suggest i do to A. find out if the cat on there is stock and B. what cat should i get, in respect to the 2 headers listed, if i need one? _____________________________ 99 Civic EX Coupe Post #: 1

The reason I was saying the one piece would be a better choice is because it has slightly better flow that the two piece because of no flange disrupting flow. That's all. I didn't mean for it to sounds like the two piece is horrible, lol my bad about that. _____________________________ JP 2001 Civic EX Coupe MT "Hokey religions and ancient weapons are no substitute for a good blaster at your side” (in reply to tarheels131) Post #: 7

Make sure you use lock-tite or whatever on the bolts, especially the ones on the two-piece joint. Mine came off by themselves, blew the gasket, and I had a hell of a day fixing it all without those bolts it came with. I had to go to Ace Hardware and buy different bolts and lock nuts and lock washers and it was a pain. Also, it's easier to put together outside of the car, that way you can use a plain wrench on the o2 sensor instead of renting the special socket from the auto parts store, and you'll be able to get the joint bolts tightened down better. And about the cat, you should buy a high-flow one, it's worth it. I don't think they make a direct fit one for your civic, so you'll have to buy a universal one and have an exhaust shop weld it on. _____________________________ Vote for Barack Obama if you care about our country!
