has anyone tried their exhaust its a 5 inch to the muffler and 4 inch out

 

5" in and 4" out....hum never seen a setup like that, personally I don't see the point in payin for 5" unless your plannin on puttin out alot of power, I kept the factory 4" its good pipe with good bends and I deleted the muffler sounds great, doesn't drone bad on the highway and gave it a real deep tone, I left the cat for highway to keep the noise down, most ppl say droppin the cat doesn't do much except make it noisy but if ya wanna be noisy drop um both...
