Since I love the GT look in the rear I have decided to take the plunge and convert my single exhaust to dual GT type exhaust. New valance tips, et. I am going to let a local guy build it custom for me and have pretty much decided on FlowMaster mufflers & no resonators. My question is in the header department. I see them available from all manufactures with prices all over the map. I am leaning towards the cheap "Tri-Y". Also nobody wants to tell me the collector size of them, I'm assuming 2.25"? Can anyone comment on what headers to use and should I paint them with some hi-temp black before they go on? Remember this is a weekend driver not some fire breathing monster. Any words of wisdom along the way would be appreciated. I know about the dropping the power steering and moving the brake lines. Also should I just be able to hook up the backup lights to the pigtails already in the trunk and have them work, or will I be into more wiring? Boy I sure can ramble !!!!

I agree that the gt style look good.
1st i would suggest forgetting the flowmasters. They have done a great marketing job, but the preformance is not the best. Dynomax make better performance and are not as annoying. You get a real motor sound and not a flow made sound.
I found out by experience that the high temp paint will not stay on. I sand blasted and repainted 2x's. You can find headers that have the ceramic coating in the over the counter parts. Last much longer. Paint will burn of within a few months. Discolor almost immediately.

Gary, the Tri-Y's are the "hot lick" for street use. I install them as often as I can, even on 2V stockers that just want a dual exhaust sound and performance upgrade. Headman makes them and all of the vendors sell their units. Shop them around as I think that you can get them for under a hundred dollars from Summit. The collecter diameter is 2 1/2 inches. The headers come with gaskets and reducers. I do not recomend using the header gaskets that come with the kit as they are real chinsey! Get a HIGH quality heat resistant header paint of your choice and put lots of coats on the headers before you install them. You will be happy happy with the results Gary. Alex

Gary,
If it was me I would go with the Tri-Y or the shorty style just for clearance if not anything else. I would have them coated or painted because this will make them last alot longer. You need to let me know where you are getting this done because I'm over in Rowlett and am looking for a good recommendation, are they going to use mandrel style bending when they form your pipes?

Just my 2cents

I'm running Hookers and 2 chamber Flowmasters...no problems..BUT the 2 chambers are noisy..suggest 3 chamber if you want it quite...

The shop jet coated my headers and I'm pleased with the look..but ask me again next year

Contrary to advertisements, ceramic or jet hot or htc, whatever you want to call it, will eventually rust. The Hedmanns on the coupe, 3 or 4 years old are rusting, Hedmann has a lifetime warranty but I can't remember if I ever sent the card in when I put them on. But to Gary's question, I'll agree with Alex, for a basically stock 289, the Tri-y's will work great for your low end torque and they hug the floorpans close so they won't hang down and get beat up on speed bumps. The tri-y won't sound the same as a long 4 tube, but with the Flowmasters you'll never know the difference. As far as paint, strip the factory crap off and get some good Hi-temp paint, not the cheap Walmart-Kmart, use VHT brand or Eastwoods. Words of experience...
