    I have been looking for a complete exhaust system for my 1984 with a 305 V8. I am interested in installing headers, y pipe, perhaps a new cat and tail pipe sections. It can be either single or I would prefer a duel set up. Any ideas/suggestions out there? Thanks:bow:

    I have the same rig as you. I opted for 2 1/4 pipes coming off the factory manifolds to retain the EFE valve for quicker engine warmups in the winter. We have no smog up here, so I eliminated the cats and decided on running a pair of Dynomax Super Turbos.

    Before you spend the dough on a complete pre-bent system, I suggest you stop by a local exhaust shop and see how much they'll charge you for a custom-bent setup. :thumb:

    you can order a 2.25 -2.5 fully mandrel bent duel exhaust kit from hooker. can be ordered for headers or manifolds and dosent come with mufflers. I ordered one from PAW years ago, but have seen them listed a few months ago in catalogs. It will say its for "off road use only" because it eliminates the cat. hope this helps.

    Thanks for the info. I will stop in or make a few calls to some local shops to see what they can do for me.

    I have '84. I put on heddman headers and true duals. with 2 chamber flowmasters. I didnt have the cats put on. AFter a month of driving, the fumes were so bad and the noise was raspy, a lil too much for my taste, so I went back to muff shop and had 2 Catco cats put in. I didnt lose any power at all and it is now quiet and no more fumes.

    i seggest you put them out the side behind the rear shackle. I have 2.25 out of heddman headers through flow masters , fumes and sound was horrid when i had to cut them to do a shackle flip. Extended them 6 inches to come out behind the hanger no more fumes or raspy sound. deep and mellow
