I would like to put a dual system on with headers to replace my stock single. I would like to know from anyone who has done this if there is a good system that I would be able to install myself (no welding). If anyone would recommend theirs please let me know what you have and what I need to look forward to.

I converted my 66 single exhaust to dual. I also put on a set of hedman hedders. The Hedders fit perfect with no modifications, I bought the dual setup from Mustangs Unlimited with 2 chamber flowmasters. I took off the old system myself, put the hedders on myself but theexhaust needed to be cut and bent a bit at the H-pipe so I took the car to a local shop and the bent the pipe correctly fitted everything and welded it all up for a grand total of $40. I wanted to do it mysefl at first but, I figured for $40 it was worth it to get it all done real good the first time. It sounds really good too.

Thanks for the reply. I was wondering what model hedmans you have. Also did you buy the ceramic coated style? I was leaning toward the hedmans or flowtech and was planning on buying the exhaust from NPD or Unlimited. Did you have any problems with drilling new holes for the hangers?

After I installed my JBA's I just drove it with uncapped headers to the local muffler shop. For $325, they installed a custom exhaust from the backs of the headers to the exhaust tips. This included all parts and labor and Dynomax Super Turbo mufflers. I figured the parts alone would come close to that, and my system is all mandrel bent, and fits like a glove.

I have the Hooker Super Comps. They fit very well but did require minor dings be "Installed" by the steering linkage, etc. Something not to be unexpected when installing headers. JBA & Hedmann make very good units, JBA probably the best. With the shorties, there are plenty of advantage compared to the extra long super comps (like I have), not only from an install point but performance as well. When I did mine back in 1986, there were shorties out there, but not near the quality of today. If I had to do it today, I would likely use the JBA shorties.

i have flowtech that i ordered from jc whitney and they are pos's. not to say flowtech makes cheap headders. but the ones that jc whitney sells are cheap. the instructions were made on a copying machine and were full of mispellings and all kinds of errors. not that im an english major or anything but i figured a company would be a little more professional. i could have done better with my computer. so who knows, maybe they arent flowtech, maybe theyre bootlegs. either way im stuck with em for a while.

I have a set of the Hedman ceramic coated hedders on the Toy. They fit great with no interfearance with the steering. I rigged up some old mufflers and flex pipe to get it to a local muffler shop. They installed a 2-1/4 inch exhaust from the
hedders back for $200 mufflers included.
