Posted By Discussion Topic: Dual Exhaust. -- page: 1 2     Gary M. 03-04-2014 @ 7:08 PM reply profile send p.m. Member Posts: 218 Joined: Oct 2009 Hi guys, Im looking for some advice on purchasing and installing dual exhaust on my 39 Tudor Standard. First off, my system is in good shape so I would like to salvage as much as I can. What I would like to do is cut off the cross over pipe and cap it off, then start from the other manifold and run back. Is there a company out there that manufactures pre-bent pipes for dual systems, or do they have to be custom made ? Also, is there a site that shows a proven method of running the pipes through the frame without interfering with any wires or brake lines or steering gear ? Any info would be great. Thanks..... ford38v8 03-04-2014 @ 10:53 PM reply profile send p.m. Senior Posts: 2780 Joined: Oct 2009 Gary, any decent muffler shop can do it. Have them model the tail pipe identical to the existing pipe, as left and right are interchangeable. The manifold pipe will take a U turn to the rear, and will interfere with the elbow of the clutch pedal. To fix this, a hot spot from a torch and a light tap with a ball peen will do the trick.

Are there any company's that produce the pipe already pre bent? I've never actually seen it in any parts catalogues.Thanks again.... bobgrice 03-05-2014 @ 2:46 AM reply profile send p.m. Member Posts: 4 Joined: Sep 2010 There are a couple of places that sell a dual conversion kit, ready to install. Here is a link to one: http://macsautoparts.com/early-v8-ford-mercury-dual-exhaust-conversion-set-ford-passenger-91a-5255-mext/camid/F30/cp/UQ0IEPTZ1000023/ I believe (please confirm) that the above set is for an original front-exit manifold. There are some vendors who sell a reproduction of an original rear-exit driver's side manifold. Good luck! Be prepared, as mentioned above, to massage the driver's side exhaust pipe where the clutch arm elbow is. The elbow on mine hit the pipe when the pedal was about 1" from the floor. I used a hydraulic press to flatten the pipe in that area, but heat & smash will probably work just fine.

I know he has kits that include his headers, but he may also have kits that could be used with stock exhaust manifolds.

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..... 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. 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.

Jim also supplies really nice hangers with the kit. Jim is highly recommended.

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!
