Mine run through a box as well. It does have some muffling effect but so does a Y pipe. The box is the easiest and cheapest way to get around all the overpriced Y pipe and elbows. It is bolted down with springs on top like a wet line kit for a semi truck. This allows flex while holding securely. The box is also the cleanest looking way to mount them.
can you post a pic of what this looks like?
