resonator replacement, glass pack Options

[klm317]

i currently have a magnaflow muffler on my stock exhaust and i was wondering if replacing the stock resonator with a cherry-bomb glass pack would help to make the exhaust louder without making it ricy. my exhaust right now has a slight purr buy definitly needs to be louder in my opinion. i really don't know what else i could do to make it any louder without doing a custum cat-back, which wouldn't work due to my small budget. thanks for any input.

Cherry Bombs are 1950s technology with absolutely atrocious flow characteristics. To reduce the volume level, the interior of the glass back is louvered, directing bits of the exhaust stream into the glass packing. Think of the effect of dozens or hundreds (depending on the glasspack's length) of intrustions into the exhaust flow. Turbulence anyone?

The stock resonator is less a volume reducer than it is a tone moderator. It prevents the exact ricey sound you want to avoid -- that nasty buzz you hear from poorly designed exhausts.

If you're looking to replace the stock resonator, which is an entirely different form of sound suppression than a glass pack, I suggest sticking with MagnaFlow and get one of their PowerPacks, which are perforated straight-through mufflers rather than the louvered design of a Cherry Bomb. You'll also benefit from superior insulation materials (stainless steel wool and ceramic fibres instead of fibreglass), so it will last longer. The longer the mid-muffler, the lower the overall volume. You want it louder, get a short mid-muffler.

Excellent advice.

Yeah he's right about that. I used a glasspack when I had my 7afe engine and it sucked s***! Well anyways, just get a magnaflow resonator muffler from summit racing. If anything get something from 20" or lower if you are still using the factory pipe size (smaller resonator to replace factory one). It's louder, not ricey but deep and sounds great
