300ex exhaust

[Caseys 300ex]

Well i have a Cobra exhaust for now and i was wondering if there is anyway to make it quieter? Also can u use house insulation as packing?

i don't think the cobra has any way of mounting a supertrapp. you should look into getting another exhaust, like a supertrapp or big gun or hmf. they're quieter than the cobra and make more power. you can use insulation, but it will burn out faster.
