Cat to racing exhaust
 

I recently bought a racing exhaust from protuninglab.com for my 2000 civic lx 4dr.. but the prob is, I have the cat, then a small pipe that hooks from the cat to the intermediate pipe... That small pipe after the cat, has a 3-bolt connection to the cat, but a 2-bolt connection to the stock muffler, the racing muffler I bought has a 3 bolt connection at that point... Any commonly searched-for pipe that I can buy for it to hook up properly??

you are probably looking to convert your exhaust to the EX/SI style.

This the first thread you see when looking at the exhaust section. it is a sticky, so it will never be moved.

Well, It's this exhaust: http://www.velocityfactor.net/prodimages/11770_WEBL.jpg ... And I just want to hook it up asap. Seems as though I'd need someone to like customize it onto the car or something. Right now I have no muffler at all on it. Will a test pipe hook on to the stock 2-prong connection?? Like this: http://www.redlinemotive.com/images/...-test-pipe.jpg ... What is the quickest way to get this hooked up? Cuz my car seems to be guzzling gas like a truck, not to mention I have a huge cold air intake on the thing already.

ok, now I saw your link.... now I get it kinda lol... Gotta get the 4-2-1 header and a new cat... right?

-Reuses old exhaust manifold, old O2 sensor, old wires
-Requires welding and 1/4" thick plate(s) of steel. Recommend also having exhaust paint
