DC Sports usually makes some in the $400 range, and you can always check out Craigslist to get em cheaper. If G22 were here he'd be saying Bisimoto, I don't know if Bisi makes headers for your engine and they woudn't be in your price range including an install though.

Currently, I don't believe neither DC Sports or Bisimoto have them for the 7th generation Accord V6.

Oh wow I completely breezed over the 3L part of the title. I don't think ANYONE makes headers for that V6. Someone correct me if I'm wrong, but I think best bet is to go custom exhaust in this situation.

Googled it, in a HT forum post someone says the first bit of the exhaust manifold is actually welded to the head, so there's no way to change it.

The way the 7th gen Accord V6 set-up is: there are two separate cat converters attached to the respective front and rear cylinder heads. A J-pipe is attached to the two separate cat converters, which then run to third cat converter. Then there is still the cat-back exhaust system.

The J-pipe is what a lot of people have done already on their 7th and 8th gen Accord V6. It is not rare.

Current, Honda Accord V6 exhaust system are not like the days of old.

I've never touched a V6 in my life outside my friend's old 86 Bronco, so I wouldn't even know where to start with this silly manifold-welded-to-the-block thing

Go to a local shop that you trust and ask them about your options. This is the best bet. My favorite mechanic here gave me a custom catback for way cheap, and IMHO it's (or rather it was ) the nicest sounding Accord around. Shortly after I got mine done someone in my neighborhood with a 96 Accord got the exact same setup from the same shop, so you know it sounded good I would post a picture of our cars together but I don't know the guy and wouldn't want to go posting pics of his car all over the place.
