After Market Muffler
Thanks Ken Bailey
Changing the muffler helps, but you're still stuck with the Ford small size pipes and non mandrel bends so it's sort of a band aid etc. Get a system that allows you to keep the cat in place or that uses a cat test pipe so you can reinstall the cat for dealer visits etc. MBRP and AFE both make systems that will do that for you and the cost is actually pretty low ands then you';ll get teh max flow rate and EGT drop. Most folks that do a muffler later do a system anyway and then they have spent money twice and used mufflers don't sell for much either. Next would be an intake so you have flow in and out, they key to diesel efficiency etc. Call us if you have any questions we'll be glad to help you.
