I was looking at the summit website and saw an american thunder exhaust kit for 65-66 (part #FLO-17273), will this fit my 67? About a month ago it said it would fit 65-73, is this the same one? I heard it doesnt fit staggered shocks, what are staggered shocks? Is the kit a good deal for $319.95? Any thoughts are appreciated. THanks.

I can tell you what staggered shocks are. One rear shock is further forward than the other. Only found on top-of-the-line performance Stangs.

Beilieve it or not, staggered shocks were on '71 Pintos too.

As far as the fit for the mufflers, call thier 'knowledgeable' staff... It's toll a free number. If the catalog says it fits, take them for their word. Good luck.

You can take your 'Stang to any muffler shop such as Meineke, and they can fit any muffler on you your 'Standg you wish. The shock placement will make no difference to these folks. They can fabricate around them. You can get flowmasters which give you a great rumble for far less than that price. Go to a muffler shop and ask questions. The internet is not all cracked up to be the ultimate answering machine.

Muffler shop pipes are crush bent.... which produces a major restriction in flow. The best thing about the Flowmaster product, is that it's a full 2.5" diameter mandrel bent exhaust system.

Muffler shop equipment crushes the sh*t out of the pipe in making those tight bends required to go up and over the rear axle housing.

I know of a multitude of people who have installed the Flowmaster tailpipes on various year early stangs... including the 67-73's. If you don't want the whole system, the Flowmaster tailpipes (by themselves) are only $99/pair, and are the best $99 you'll spend on a street exhaust system for your stang.

A word about mufflers...

There isn't much room under an early mustang. Do NOT go after long mufflers. They don't fit. A long muffler's outlet will be right up against the rear axle housing, making tailpipe installation a serious PITA. I saw a magazine article where they tried to install Flowmaster's latest big, long, super 'universal' mufflers.... but had to run small tailpipes at pretty much a 90 degree angle up out of the outlet to get it up and over the axle housing. Shorter is better!

Some places produce 79-93 (FOX) mustang specific mufflers, as those cars are short as well. These work well on the early cars too.

Good Luck!

Re Flowmaster and Meineke. They were over 100 higher than an independant here in S. Fl. Re mandrel bending, there is a co. here that does it. Their bending is computer operated. The mandrel bent kit that I saw featured in M&Fords was in sections and not one piece tail pipes. Part of the mandrel deal???

Be very wary of muffler shops that, when asked, say their pipe is mandrel bent. There is probably a misunderstanding, because mandrel bending machines are VERY expensive, and not generally used by 'everyday' muffler shops. They are a high volume only type deal. 99.999% of all muffler shops use regular hydraulic benders.

The 'mandrel' referred to in the name refers to a large segmented 'snake' that is inserted into the pipe prior to bending that keeps the pipe from collapsing.

If they don't have this, it's not mandrel bending.

below are pictures comparing the two...

Go here for a little information on the process.

I'd say good idea but it does get a little noisey when cruising at about 60. It also soots top the nice stuff underneath. If you don't mind the above stuff do it. A little co (read carbon monoxide) might find it's way inside too.

Man, you guys are smart. I learned something today about bending pipes for the exhaust system. Some race team oughta' hire you guys to work on their racers.
I had flowmasters put on my old '65 'Stang with a 2v 289, and I get the rumble and power I like, and the Meineke guy fabricated it for me. Hell, all he used was a torch and some ingenuity with selecting the pipes that were already bent to the right size. God knows how they were bent, but in my estimation, bent is bent, no matter the method.
But I'm an old hot rodder, and haven't kept up with the latest lingo and equipment.
Nice job of answering his question guys.
