Yep one of the first things I did when prepping the engine for installation. They were so off I estimated the exhaust was blocked by 25% the intake a little less. Did you have time to look at your silencer? Mine is packed with white mterial maybe fiberglass Im not sure. It is awful loud, and I read yours was too. Curious what you did or are going to do.. Love the Sabre, just started using it....
