Exhaust system sound simulation

Post by firebirdgangsta » Thu May 07, 2015 9:01 pm

I just had a thought. What if there was a way to figure out what an exhaust system would sound like before you spend all kinds of money on it? Maybe software? Or is there like a database with all kinds of sound clips (something more reliable than YouTube). Flowmaster or magnaflow or any other brands will sound completely different depending on the engine. A flow master 40 Delta flow would sound completely different between a Hyundai 2.7ltr V6, Benz 3.2 V6, Subaru H4 or H6 etc.

Any ideas?

I think it is a great idea, but it would be a challenge to do yourself. You may be better crowd sourcing the video/audio into an app of some sort. Then it is just a matter of structured data - which is what I happen to love.

Theoretically you could do it with sound filters. But then you'd have to do some weird analysis on all kinds of mufflers and pipe types. But yeah that could work. Maybe a YouTube channel with approved submissions that have to meet basic standards like video and sound quality etc.

One way it could be done is if you take one basic type of vehicle, say a 305 V8 Firebird, or maybe an Olds Aurora, and you quickly zip on a popular muffler with like an impact and zip ties, like a Flowmaster 80 and start it up and rev it a few times while recording. Then you zip it off and put on a Magnaflow or a glasspack and do the same thing. Then you have a sound comparison for that vehicle.
