Ansa Exhaust

I would always get gaskets.....

As my mechanic told me, if you don't get new gaskets and don't line everything up 100% correct, you could get a leak....which could send a concentrated blast of scalding hot air (like a blowtorch) at an area on your engine block/body/trunk/who knows. Which might not be such a great thing.

 

I would get the two donut gaskets that are bought from GT Car Parts in scottsdale arizona for around $10 each, you should also use three news bolts and nuts on each end, so a total of 6 bolts and 6 nuts for the two flanges, the ANSA should mount to your spring mounts with little to no modification.

 

A local exhaust shop should have the doughnut gaskets, mine did........

I'd make sure to use locking style crimped nuts (nylocks would melt....) at the triflanges, as well...the later cars used spring loaded bolts at the left side inlet pipe to allow for the slight front-rear rocking motion of the engine.....it tends to work the bolts loose!

Or tack weld them, what the he11.........Rock on....

 

Sage advice from Big Tex here. The bolts can work loose and should be checked periodically. That happened to my car, also a 1976 fiberglass GTB, and a lost bolt was noted the first time I brought my car in for servicing after I bought it.

Hopefully. It depends on which used ANSA muffler you bought. Some of the older ANSA mufflers (I'm not sure which part #) were made for the 1978-1980 models with the full muffler shield and the tips might not clear your valance.

You'll like the ANSA muffler. I like mine. It's a little tinny sounding until it heats up and then it makes the right noise. It looks good too, especially with that early rear valance and the muffler hanging out there for all to see.

Bubba,

When you get your ANSAs mounted, leave those screens off. Put them on when you show your GTBs.

The early GTBs didn't have a heat shield. The ANSA muffler body will be pretty close to the fiberglass panel just above which is the floor of the luggage compartment. It's a double-walled fiberglass panel with insulation inside. My muffler body managed to burn a one inch hole in the outer wall. I installed some heat resistant/reflective material (the same material used in F40 engine bays) to prevent any future damage:
