I just bought a sc'd AP1 with a tp and a catback(can't remember what brand). It is missing that sound my old stock NA had with an AEM intake a skunk2 catback. I had a lot more rumble and bass before. Now its pretty quiet until more than 1/5 throttle. Now I am not saying I don't like it, it does have a nice purr, but its missing something. Are all superchargers quiet like that or is is just my setup. What can I do to add some more db?

 

It's your setup. You could sale the exhaust and get something a bit more to your taste. Just be careful, the charger will make the exhaust louder.

 

Putting the cat back on might make it alittle deeper.
