ok, this is as good as any place to fire off my first muffler/exhaust question. I have a '02 3.0 Ranger XLT extended cab. What is the factory size of the inlet tubing to the stock muffler? 2.00? 2.25? I want a Flowmaster 50 Series Delta Flow (i've had enough LOUD exhausts in my day). I crawled underneath and saw 2 pre cats on the factory y pipes and then an oxygen sensor and THEN another CAT!!! I live in FL, no testing, etc. Can i get a shop to cut off that 3rd cat and install the exhaust? no O2 sensor issues shuold be all good. What size inlet and dual outlet should I get on th muffler too? thanks!!
