    That doesn't look like a high flow cat, but I'm far from an expert...but am also interested in answer to this question.

    94008 model if that helps.
    I have researched videos and those don't help with the dB difference.

    Stock Catalytic vs Aftermarket

    Looking to change my exhaust system up a little bit. I have the Magnaflow 14815 single-in dual-out. I recently fixed most exhaust leaks and now the whole setup is wayy to quiet. I am looking at a Magnaflow High Flow Cat. I ran the system before with no cat and loved the sound. I am looking to use a high flow cat to reduce the smell and some of the rasp, but not the sound. Anyone here using a high flow cat, and can tell me how much the sound changed vs no cat/stock cat?
Working...
