I know there are two types of tailpipe extensions for '70 Mach 1s with dual exhaust, the oval tips and the square tips. I was always under the impression that only the 428 cars got the oval tips, but I've noticed both the 'Mustang Recognition Guide' and the '1970 Mustang Illustrated Facts Guide' state that the oval tips were used on both the 428 and the 351C 4V cars.I'm pretty sure the square tips on my 84k mile M code are original because I doubt the previous owners would have replaced them with anything but Kmart specials if they had the chance. Does anyone have any insight in this? ------------------

Steve, post a picture of your tips, because I've never heard of "square tips" before. They should be oval, all 1970 Mach 1's got the same tips when the dual exhaust with cut-out rear valance was present. I've commonly seen "generic" square tips used before in place of the OE tips, because of the rarity and expense of the OE tips. They are just generic parts store tips, perhaps this is the source of your confusion, because the use of the square parts-store tips is so widespread.

RICKS,
was there a "rolled" and non-rolled" exhaust tip used at on time on the Machs?I may need to explain more..I'll try.
The rolled exhust tip had a more rounded end as the metal was rolled under to form an end as compared to the non-rolled which was just cut square,raw edge..did I expalin well enough?

These are the ones I have, they have a Ford part number of D0ZZ-5255-A. They are squarish and the ends aren't rolled:
 These are the ones I call oval, I think they are D0ZZ-5255-B? They are shorter and the ends are rolled:

Steve,
I found what you are looking for in "Mustang: 1964 1/2 - 1973 Restroration Guide." On page 304 - 305 is a complete break down of the exhaust systems for 1970 Mustangs. The break down show's that DOZZ-5255-A is for the left hand side and DOZZ-5255-B is for the right hand side. There is also a picture of the "oval tips" and the caption reads: "The split exhaust tips were replaced with this flat trumpet with an oval, angular-cut opening for 1970."
I can scan the page for you and e-mail it to you if you like. Just let me know.  Dave & Terri ------------------

Paul,
Well, I just tried to use our scanner and found out it's FUBAR.  What details would you like? I can at least type it all in an e-mail or here on the Forum. Time to price check scanners.  Dave & Terri ------------------

Steve and I have had a few conversations about this subject. My problem is that my Mach1 had some angle cut off-the-wall exhaust tips put on by the previous owner. I'm just trying to get this detail as correct as possible. As you can see from Steve's images, there seems to be a wide range of differences in the same tip. ------------------

O.K., when you said "square", I immediately thought of aftermarket tips that are actual rectangles with sharp corners. For O.E. tips I've seen both the rolled-lip and the non-rolled Ford tips, but I've always thought of them all as "oval", so that's where I got off track. Ford parts text calls for a D0ZZ-5255-A LH and D0ZZ-5255-B RH, which are the longer tailpipe assemblies as shown in your first image. Every one of these I've ever seen have the non-rolled straigh-cut tip. The rolled tip-only pieces are universal RH & LH, and do not have a part # listed in the Ford text, and I wonder if maybe they were sold as an over-the-counter accessory out of Ford's Performance Parts catalog. This is an area that I'm a bit fuzzy on, just like you guys are. Where did you get that picture of the rolled tips, Steve? I would like to know the part # on the box in the background. Anyhow, I think the unique LH-only and RH-only non-rolled tailpipes are what I predominantly see on concours cars, because they match the Ford #'s in the parts text. But whether that part was changed in later years, and was originally a rolled tip, or whether cars at one plant got rolled tips, and other plants didn't, or etc.etc.etc.. I don't really know. My unrestored '70 Mach is unfortunately a 351-2V Windsor car with single exhaust, so I've got no good reference. But I think my "Ford accessory" theory for the rolled-tip RH or LH universal tips would be my first guess, and I may be wrong.

Thank you, Dave! Now I remember those numbers being right and left. Rick, that pic of the short oval rolled end tips came from ebay a while ago. I'd like the part number of those, too.  ------------------

D0ZA-5C262-C is the engineering # that's stamped into the piece. The actual part # would be on the box, which isn't around since that's a used tip.

Stainless Specialties has a new exhaust tip called the 'Rectangle;E' that is being advertised in Street Rodder magazine that looks just like the tip I referred to as 'oval.' It's 100% stainless, too. They have it listed for $149. It looks real nice in the ad, I emailed asking for dimensions.Here is their web site, although they don't have the new tips on it.

Quick response from these guys! "Dimensions of the Rectangle Tip: 2" H x 7.5" W x 10 " L
Inlet size: 2", 2.25", 2.5" or 3"." I'll have to drag out my rear valance and see what those openings are. ------------------

Steve, my reccolection (for what that's worth lol) is that THESE are correct for a 70.
I don't remember any distinction between SB or BB tips or 69's or 70's.
