The cat will 100% get rid of the smell..
I have the weapon r headers with a 200cel cat welded in. Good gains all round. VTEC is awesome now.
Weapon r headers + shipping - $600
welding + install - $250
high flow cat - $200
Also, you will need a defouler (extended bit of metal ~$15) for the secondary o2 sensor that plugs in after the cat. Otherwise your car may throw an error code due to the extra air flow.
oh, and the primary o2 sensor is facing the wrong way, so when they cut a piece out of the test pipe to weld in the cat, get the front section of the test pipe (which connects to the headers) rotated 180deg.
Apart from all those things, its a really good header. well build, good gains and cheapish!
Feel free to ask any questions..
