    Hello everyone,

    Looking for exhaust recommendations for the '84 Mustang that is more on the quiet side.

    thank you

    I put a new exhaust on my 84 turbo using Walker and AP parts. The muffler was easy for a single but the mid pipe and tail pipe were very hard to find. I believe I went with Dynomax Turbo and I think it's a bit too quiet.

    I did both my 85 5.0 and 84 GT turbo.

    I'll look into Dynomax and Borla, thank you.

    For a 2.3t get the exhaust from Stinger. 3" down back through the muffler then down to a 2.5" tailpipe.

    I have Dynomax turbo mufflers on my 88 5.0. Sound great and are not too loud. The sound they make at around 45-50 mph in 3rd gear (AOD) sound so sweet.
