engine louder?
My SLP exaust got louder over time. I believe the packing in the muffler begins to loosen up a bit and let a few more decibles out. If your mufflers are fiberglass packed, I bet that's whats happening.

more to light off when it goes boom. Like comparing a regular firecracker to a
M-80.
