Posted By Discussion Topic: Dual Exhaust. -- page: 1 2     Gary M. 03-08-2014 @ 6:02 PM reply profile send p.m. Member Posts: 218 Joined: Oct 2009 Well I did install a 6v priming fuel pump right outside the gas tank just to push the gas up to the carb after the car has sat for long periods. It probably wouldn't be a bad idea to put a shield around it considering it also has a filter after it. Safety first! The rest of the fuel line should be ok . Thanks again..... trjford8 03-07-2014 @ 7:33 PM reply profile send p.m. Senior Posts: 4234 Joined: Oct 2009 You should not need any heat shields as long as the exhaust pipe is not right next to the line. I have had exhaust(tail pipes0 with in a couple of inches of the gas line and with 3 inches of a new plastic gas tank and never had a problem.

While inspecting the underside of the car for clearances, I noticed that the fuel line runs very close to where the left side pipes and muffler will run, especially where the pipe runs over the rear axle. Has anyone who added duals to their car had to add any heat shields or move any sections of the fuel line since this car was never made with duals from the factory? Thanks again.... 37 Coupe 03-07-2014 @ 8:00 AM reply profile send p.m. Member Posts: 362 Joined: Oct 2009 MichV8 is the dual exhaust you bought from Red's from the original manifolds or his steel headers? I look on his site and do not see a dual exhaust conversion without headers. I myself always prefer original cast iron exhaust manifolds or Fenton's if they fit,never cared for steel headers that have a shorter life. I have a set of duals from a company called Arasco on my 37,they used to advertise in Hemming's but do not see the ads anymore. The setup works but it was pretty frustrating,I think they made it to bump into anypart of the frame and chassis they could. I felt to I wanted to put this all on in my garage and not take to a shop. In my area it is hard to find a muffler shop to do this anymore they just don't want to take the time,and I mean the locally owned ones not the big names. You would think they would take anywork they could the way exhaust last with newer cars,my 99 Explorer still has the complete exhaust system from the factory. I had a 63 Ford with a 390 and factory duals my dad bought new and it required exhaust work about every other year from new.

Easy to avoid if you prop the pedal (or have someone hold it) to the floor during installation to ensure that there will be no interference. Alan's comment about heating and dimpling the pipe might seem like it would restrict flow, but given that you will now have twice the flow as with a single pipe, it is of no practical consequence.

Although I did not personally install, my restoration guy had very little challenge getting it to fit. The tightest spot was passing through left frame hole, but required no modification. I used the mid-length Smitty mufflers. As expected, we did have to reduce length of tailpipes to fit our choice of Ford script tailpipe extensions. Turned out great!

Jim also supplies really nice hangers with the kit. Jim is highly recommended. supereal 03-05-2014 @ 7:51 PM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 The reason the left side head pipe is expensive is that it is the key to a successful installation. Otherwise, the rest is fairly straightforward. Most prefab left pipes don't just bolt on. While it is tempting to DIY, a good job is best left to the pros who can compensate for the thermal expansion and avoid rattles. They do earn their money. At our shop, we do sublet the job, and never regret it. Pickup 03-05-2014 @ 6:39 PM reply profile send p.m. Member Posts: 26 Joined: Jun 2010 I bought the left and right pipes from engine to mufflers from Mac's for about $100. I used a straight pipe on the left side to replace the muffler and for the left tail pipe, I took the right tail pipe to a muffler shop and told them to make the left pipe just the opposite of the right pipe. That cost about $60. Every thing fit well, but I think I am going to put some kind of muffler on the left side. Gary M. 03-05-2014 @ 5:58 PM reply profile send p.m. Member Posts: 218 Joined: Oct 2009 Ive looked at both sites and found the pipes from the manifolds to the mufflers, which I assume will need some tweaking after installation. However, I only found one company that sells the 91A5256L left tail pipe. C and G sells it for three times the price of the right pipe. Supply and demand I guess ! Does anyone know of any other companies that produce that pipe? Thanks again for all your help guys.....
