JULY 1965 GT Exhaust??

6hypo5conv_old · October 7, 2008 at 12:05 PM

Where can I get the most accurate REPRODUCTION exhaust for my JULY 1965 DEARBORN GT Convertible?

6hypo5conv_old · October 11, 2008 at 7:09 AM

Anyone got a complete NOS system laying around?? what should I do for exhaust??

NPD for the repro. The NOS systems are not easy to find, but they're out there.

OK, Thanks Round2K!! so NPD has the best most accurate reproduction on the market?? this is good to hear because there is a location that is close to my restorer.

Make sure what you buy is made by Motive...

6hypo5conv_old · October 14, 2008 at 9:35 AM

OK, Motive: Is this the brand/manufacturer that NPD sells?? how can I be sure that I get this brand regardless of who I buy it from? is this the best reproduction system on the market? Thanks!

66KGT_old · October 14, 2008 at 9:53 AM

Ask.... I know K.A.R. sells Motive though they are a little pricey, I believe NPD does as well although they may carry another manufacturer along with the Motive so be sure to specify you want the Motive.

6hypo5conv_old · October 14, 2008 at 10:43 AM

Any way to buy from Motive direct? how would I know when my system arrives if its Motive or not? or other brand for that matter?

66KGT_old · October 14, 2008 at 5:28 PM

Don't know if they sell direct or not.

Here's their website:

Thanks for the link to the Motive site.....I'm looking at the charts and see the flowmaster and some other turbo mufflers....do they not carry a completely stock/original type muffler??

6hypo5conv_old · October 15, 2008 at 7:38 AM

I have looked more at the Motive site and figured out that they DO offer a complete stock/original system.

My question is would my JULY 1965 Dearborn built K convertible get the system WITH or WITHOUT the resonators?? I know it DOES NOT use the earlier transverse muffler system that was used on 64.5 cars, but am unsure as to the date that the system used the resonators....anyone know??

With resonators, that's the only way they came at that time.

Motive is one of several vendors that distributes their exhaust systems through NPD. The straight through GT duals with the resonators replaced the Arvinode system in late March of '65, and there are several companie reproducing them as they are the most common Mustang dual exhuast system.

If you own a HiPo there were three possible exhaust systems:

Start of production until 10/15/64: transverse duals.

10/15/64 until 3/22/65: Arvinode.

3/22/65 through '67: straight through GT duals.

There are some conflicting dates in the Ford parts books about the transistion from the Arvinode over to the GT duals; 3/22/65 or 4/2/65. Sor far the latest car we have found with an Arvinode is from late March.

"Start of production until 10/15/64: transverse duals.

10/15/64 until 3/22/65: Arvinode."

Is the 10/15/64 date for the end of transverse to beginning of Arvinode locked in stone?

Also, I know the Arvinode has been discussed extensively, and thanks to you Dave in paricular for recreating the system. The setup on my fastback is long gone. What are the differences in rear frame rail exhaust hanger placement between the transverse system and the Arvinode? Do these differences even exist? Sorry, if I've changed the discussion somewhat. Thanks, Alex

The relocation toward the rear of the car and the frame rail reinforcements for GT dual exhaust hangers didn't happen until March of '65.

**One study that we need to undertake relative to the GT duals is when Ford made the change from the early mounting points in the center of the frame rail to the rear of the frame rail. Logic would dictate that the change would coincide with introduction of the GT option that included the straight through GT duals. We need to include exploration of the earliest GT cars for the rear exhaust hanger mounting points and the reinforcements that are inside the frame rails.**

As Dave has confirmed, there are several vendors that distribute their exhaust systems through NPD. Evidently I received one of the "other" vendors h-pipes from NPD after I poked a hole in mine loading the kar onto a trailer. It didn't fit worth squat and unfortunately we destroyed it trying to make it fit so I couldn't return it. Bought another h-pipe from K.A.R. (where I purchased my original system) and it fit like a glove. I will reiterate, if you purchase your exhaust from NPD BE SURE TO SPECIFY YOU WANT THE MOTIVE SYSTEM - NO SUBSTITUTIONS! They are the only ones that I've found that fit right.

6hypo5conv_old · October 16, 2008 at 1:04 PM

Has anyone bought a system recently?? if so who did you buy from and if I may how much $$ I'm looking at a listing on Ebay from Laurel Mountain Mustang (where I bought the great repro speedo cable) and they APPEAR to be selling the Motive kit for $329.00 plus shipping, I have sent an Email to check on this, its my understanding that I need the MOTIVE kit# C5ZZ-5257WRS WITH RESONATORS!! (Thanks again Charles)

6hypo5conv_old · October 16, 2008 at 3:48 PM

FYI: ALL, I just got confirmation from Laurel Mountain Mustang that the system they are selling on Ebay IS the MOTIVE system for LATE 1965 UP cars this is the 100% correct stock system (NO FLOWMASTERS) and from manifolds to MY GT trumpets its $329.00 plus $46.00 shipping which totals $375.00 in my book, and given what it is and the quality of the MOTIVE stuff I personally think that IS a good price! (I'm going to get them to throw in a set of correct nuts for the manifold studs)

6hypo5conv_old · October 18, 2008 at 6:41 AM

Are the "H" pipes the same for standard 289s v/s the HIPO manifolds?

No the 'H' pipes are unique to each application.
