FWIW and this has probably been stated a zillion times but quality and fit are superb. I put these on my 84 with a 383. Easy install. The hardest part was having my wife get the last header bolt installed on #8. She has smaller hands. I used felpro gaskets (1705 i think). Started the motor up let it get up to temp, let it get cold and retighten the bolts and no leaks. I originally tried to use Stage 8 header bolts but no joy - All of the keeper clips would have needed to be cut down. I changed over to ARP small head header bolts by recommendation of a forum member and I have had no issues. Screw them in tighten them up and no fuss no muss.
I took the exhaust parts to the local exhaust shop and they welded everything back up for $350. The did not weld to the collector I used those stainless steel wrap things with two bolts on each side like the pictures show. I can remember what they are called at the momemt but Walker makes them. I bought them from Summit for $8 each.

what do the headers NOT come with that you need? gaskets? is that it? do they come with all the bolts you need? 350 bucks sounds like a lot to weld things back up. how far apart did u take the rest of the exhaust?

you will need the bolts and gaskets(which they will sell you). you will also need to tie it in to the old exhaust. This part is not Bolt on. the Cats and rear 02 sensors need to be dealt with. EM will sell extensions that will connect to the stock exhaust after a little cutting. these can be had with or without cats.

I installed my EM LT's and RT cats a couple of weekends ago on my 93 6sp. The only mod I had to make was that I needed 3" of extra pipe added to the lefts side because the stock cat was 3" longer. I had completely removed my entire exhaust during the install, took the left side tube up to Midas and they welded in the 3" for like $15 and everything lined up and this is on a vert with the X brace. Spark plugs are no easier or harder IMO.

I was going out of my mind waiting for these to come.. Then they arrived, and I knew it had been worth it. Very nice work - These pictures don't even do them justice

Man, I wish you hadn't shown those pictures. 
Now I'm really going to go nuts waiting for mine to arrive.
Merle was great to deal with. Answered all my questions when I ordered my complete exhaust from him two days ago.

That thumbnail pic on the right looks strikingly similar to my car
Tip: if you get the extensions, pay the extra for the coated ones because I have the painted and already they are completely rusted in less than a year.

Really?? My car doesn't see rain/snow, so I'm hoping to get better results from them... At least I HOPE.. I didn't know coating was an option, or I'd have sprung for it.

Unfortunately, neither does mine. I've only logged about 2400mi since I bought the car over two years ago.
It will rust..but thats the nature of the beast. I would have prefered if they had used stainless for the extensions.

I was told there is a product sold for John Deere tractors to blacken the exhaust stack.
I have not tried it but perhaps ir is worth looking into to keep the un-coated extension from rusting.
