I've removed the snorkle, rejetted main to 165(and pilot to 48, when it comes in) and have heard about drilling the end cap to 1-3/8". I'm fine with that, but my question is about the baffles. I've heard drilling 4, 3/8" holes thru both baffles. The guy at the dealer said that it might make me lose power, not gain. Any real advice? No cash for a new muffler...:D
