Opinions Wanted: 66 Exhaust Setup

Mar 08, 2005 2 Replies

Hi All,



This topic seems to be one that is discussed off and on in this group (given what I've found using Google), but I thought I would bring it up yet again for fresh opinions on my situation. I've just upgraded to a T-5 tranny, and with things moving around slightly, the custom exhaust setup that I had installed when I got the car is no longer usable. Since I'm starting over, I would like to replace the stock exhaust manifolds with headers at this point. So, I was thinking of a setup something like the following: Heddman or Hooker or Tri-Y Long Tube Headers (ceramic coated)



2.5" pipes Dr. Gas Crossover Dynomax mufflers


66 Mustang Coupe (this is my daily driver):



- Originally a 6-cylinder, 3-spd manual. Now a 289 with a 5-spd T-5.



- Kept original 3-spd bell-housing with original solid clutch linkage.



- Manual steering



- Manual drum brakes all around. I would like to upgrade to front disc brakes in the future.



Wants:



- Some increased horsepower



- Support for future engine mods (in other words, I want the exhaust setup to help and not hinder horsepower as I do future work on the engine, without having to upgrade the exhaust again)



- Keep the ability to change plugs easily (and keep other similar maintenance as easy as it is today)



Do Not Wants:



- Maintenance & leakage issues with the headers themselves



- Ground Clearance issues



- Clutch linkage clearance issues



What do you think? Does anyone have a similar setup that they've installed and know doesn't have fit issues.....I don't really want to have to mess with bending/moving the clutch linkage around just to fit the headers. Any opinions on which headers? At this point I've ruled out shorty headers since I don't really want to make changing plugs a pain, but if you know of a set that doesn't cause that problem, then I would love to hear about it.



Any and all opinions welcomed!



Thanks, Scott



I have a '66 coupe with a 289 and a 3 speed manual that I added Edelbrock aluminum heads with roller rocker arms and intake and a Road Demon carb along with Dynomax ceramic coated headers and Flowmaster mufflers. I am about to add a T-5 trans, but there is no clutch linkage interferance with the headers as long as your linkage bushings are still there (mine aren't so I have a rattle until I replace them). I have gotten a dramatic power increase from these additions and the T-5 will only improve things further. I also have 16" Cragar SS wheels with Pirelli P-Zero Nero tires and I get great grip with them. Good luck with your upgrades!
