Throaty exhaust

MY '73 GTS HAS HALLS' BIG BORE HEADERS WITH THE EUROPEAN BIG BORE MUFFLERS. THE TUBING FROM THE HEADER TO THE MUFFLER IS 2.0" DIAMETER.(STOCK IS 1.75") I THINK IT HAS THE LOUD RUMBLE YOUR LOOKING FOR. THE MUSIC IS JUST SWEET. REGARDS, MARLIN.

According to the po, my car has "modified Ansa mufflers" Probably a Bryars exhaust system or Hal Big Bore.

My wife won't ride in it and it rattles the windows and dishes when I start it.

I also have the Hall big bores and we removed a lot of the baffling in the mufflers for even better flow. What a super sound! So nice it sets of all the car alarms as you drive down the street. When you drive into an indoor multi-level garage there's nothing but sirens, alarms and bunch of security guys by the time you park. Love those big blocks.

I have had the Hall Big Bore and they have held up almost 10 years now. I had them ceramic coated by Jet Hot Coatings and they look & sound cool. Only problem had been leaks where they attach to the manifold, but sandwiching a couple of gaskets cured the leaks.

There is a "final baffle" installed in most stock Ansa mufflers that can, with a little care, be cheaply removed to increase noise & gas flow about equally. Stick a long pipe into each chrome tailpipe; inside, it will run into a common steel washer tack-welded onto the perforated baffle. By judiciously whacking the end of the pipe, the washer can be broken loose or bent out of the way of exhaust gas flow. This happens automatically on some Panteras. If the washer breaks loose, it will 'jingle' at idle but be covered by engine noise at driving speeds. If the jingle bothers you, you'll have to slice open the muffler body & extract the loose washer. On my '72, two of the 4 washers were broken when I received the car with 13,000 miles. Note this baffle-washer is not there on real 'GTS' mufflers, which your 'Euro' Pantera may have as-stock.
