thinking of replacing it for more power, my jeep has a 4.0 with 113,000 miles.
my idea is a 2 1/4 hi flow cat-co cat and a 2 1/4 flowmaster 3 chamber delta series muffler with 2 1/4 pipe out the back.
would this work?
anyone try this?
any better suggestions?
would still like it somewhat quite on the inside.
