FI Non res vs resonated CBE

Zcup

It's really hard to judge audio differences from a vid. All I can attest to is that it sounds plenty loud (in a good way) with the 18" resonators. If you want it as loud as possible, then go with non-resonated or 12". I was leery of anything less than 18" because I wanted to minimize the likelihood of buyer's remorse. I was looking for better sound (wanted to get rid of the vacuum-cleaner-with-a-clogged-hose stock sound) not necessarily louder. That said, it is plenty louder than stock even with 18's and sounds like a beast. I doubt I would want any louder. So, it really depends on what you're trying to accomplish.

The cans sure look lower than stock, but I think its an illusion. I go over speed bumps very slowly and try not to drive too fast on a rough road where you can bounce around and bottom out. These cars look really cool lowered, but my nerves could never stand it. To many uneven roads in my area.
