hi lou.. got a question for you got an 08 is350..so say i have an axle back. and i want x pipes where the secondary cat is but still not make it true dual.. would i still benefit some? i believe you said the restriction is at the branching off of the stock exaust so with say secondary cat removal with an added x pipe an ar25 resonator and manzo axleback.. would it be worth it? thanks.
