It has had a single exhaust fitted at some stage , and I am wondering if I will get better fuel economy if I refit a dual exhaust system.
It sure needs to sound better ,, at the moment it is a little like someone sneezing into a 44gal drum .
Thoughts , opinions , experiences welcomed .

Question .. how will the flowmasters sound , are they straight thru or baffled ?
I really do want this to be quiet in the car .. a burble outside is cool ..
The mufflers I eventually use will be locally made product , so some idea of construction of the flowmasters will help me order the right thing .

They used to have sound bites of the different series mufflers. I have 50's on my truck and it is a low mellow tone that sounds like no other muffler. I have the 40's on my '95 Impala and they are a bit louder and more aggressive sounding (which I like too). They are one heavy-duty muffler also.
That's what I recommend,

The flows give a large rumble and pop with the mildest engines. Dynomax units are quieter, but still give a nice sound at cruise or accel. The ones on my '67 LeMans replicate the old-school musclecar sound. And they're a little cheaper than flows too.
The flows are a chambered muffler, the dynomax are a baffled design with packing.
