Sometimes that low-budget flex pipe can develop leaks fairly soon, so
it is best to use custom fit piping. But, you can use your existing
piping as a template for bending the new pipe. For long life, use a
stainless steel or atleast some aluminized steel (like OE).
The ZDJL is boomy, but seems to be just fine without the front stub
resonator. In fact, interior noise will be reduced, and the sound
from the tailpipe will gain a more "sporty" tone without getting
louder. The stub resonator is secured to the floorpan and is not well
isolated (just a tiny rubber mount)--some vibration is transmitted to
the passenger compartment.
Since the ZDJL is a tad boomy, and since it does not have a
turbocharger there to kill a lot of noise, I'd give some Walker
QuietFlow mufflers a try. They are designed to be low-restriction/low-
turbulence, but still have a lot sound control. Some exhaust noise
will be there, but not as loud as a "performance" muffler. Plus, you
want *some* backpressure for that naturally aspirated engine in order
to maintain exhaust velocity/scavanging. Also, don't change the pipe
diameter--bigger is not better (and neither is smaller).
