On the GMMG website it says that it has a 3" I.D. Stainless Intermediate into true dual transverse chambered sections with dual 2 3/4" I.D. polished angle cut tips, now i have a 3 inch ORY, is that what they mean by the 3" I.D? It will fit into a 3" ORY? Thanks

Also my setup is Pacesetter LT's and ORY, will this be too raspy? I've heard that GMMG gives you a good deep exhaust tone.
