I really want to hear what one sounds like, as I have one of the SP motors. I've searched on youtube and could only find grainy video with wind. And every car had flowmasters. Looking for bone stock vehicle audio. Thanks.
I don't have any audio, I bought my GS 350 in '85 before all this techno wiz bang cool stuff, but it still had the original EVERYTHING exhaust, it was pretty quiet, with a slight rumble. That's the best I can describe it. I now have headers, 2.5" pipes, with Walker 17749 "Hemi" mufflers, its a nice balance between sound, and power. It DOES NOT sound like a 5.0 Mustang with Flowmasters
The stock engine was bone quiet with the big muffler they used to put on those cars there was no rumble at all Mine was smooth as silk when I first bought it. It made more noise with the air cleaner turned over with the 2bbl carb on it. Booooaaaaaa.
