Exhaust choice for better (louder) sound

[t-royR]

I have a 69 fuel injection fastback. I want to know if there is a style of muffler that will give the car some better sound. I want it to be a little louder, like glass packs would do. I've seen the tri-Mil OTT mentioned. Wondering if that would give me the added sound I am looking for.

Thanks

YUP . . A glass will definitely make it louder!
The standard 1-3/8 four into one header will do.
And if it's to loud you can always put a single quiet muffler when you wanna be a little nicer to the neighbors.

Here's what I'm running on my 65 Squareback...

Had it custom made at the local muffler shop to bolt to the existing 1-1/2" three bolt flange header so it would clear my hitch (originally the supertrapp bolted directly to the header by way of a simple adaptor I fabbed up and exited right out the center in the rear like a short stinger). The short supertrapp is definitely loud - but surprisingly not terrible at idle and gentle cruising. But it screams when you get on it a bit!

For reference, I'm running a 1968cc dual carded engine with a fairly mild cam...

OTT style sounds good & doesn't hang down low like other exhausts.

This is for the Abarth dual tip type I posted. There is a single tip version - but I don't know if they put the special Abarth sauce in it if there is such a thing?

Not to turn the discussion too far off-topic, but I like the stock sound. I can hear it, but it doesn't drone on the highway. I like the "sewing machine" noise in preference to megaphone putt-putt. Reminds me of a well-tuned stock Porsche in its' mechanical precision, fan whoosh, and understatement. I hate the fart mufflers on Japanese cars, and I guess I'm pushing against that here, too. I drove on highways too many years and miles to like "louder."

Now back to our regularly-scheduled program...

I have run extractor/quiet pack mufflers on several of my cars, though not the Type 3s. They help slightly at the higher end, and do make a satisfying noise in the parking lot. On my Bugs they scraped unless I was careful. I even clamped a disposable angled steel plate where it dragged to save wear on the muffler.

The stock Type 3 exhaust system, if you have seen the cutaway photos, is a good approximation to an equal-length header system, and with the exception of the resonator, not very restrictive. With the intake runners on my FI '71 limiting rpms to 5K max anyway, this isn't much of a restriction at the high end, so I go with it.

I used to run a Cyclone on my old 64 notch with a 1776. Loved it. It sounded like a rally car. Exhaust popped when you took your foot off the pedal.
