Dont think the 4.8is exhaust is straight bolt on to the 3.0Diesel!The 4.8is has middle resonators,the 3.0 Diesel doesnt!But this shouldnt be problem!Out of all the factory exhausts this is the more cost effective(some 300usd less than the 4.6is!),however,
still waiting for someone to try the exhaust and give us someback on smoke and performance!The objective here is mainly for the"look" with hopefully no loss in performance and no excessive smoke.
