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!!

3 Cats...? You sure one isnt multipurpose like a muffler or something?

actually i have 3 cats then an O2 sensor than ANOTHER cat!! I want that 4th cat downstram of all the sensors, etc. gone! I talked to Flowmaster today and they seem to think it's 2" in so get a 2" in dual 2" out 50 series Delta Flow. Now i looked at the muffler and it's an offset inlet, and its positioned sideways to fit in the space, since i'm getting all new pipe does it matter if its' center inlet or offset inlet and what is the inlet size for certain?? 2? 2.25? this a 3.0 V6

just from memory i think its 2.25. Mine has a cat, some pipe, muffler, tail pipe, so yours must have been already changed or something.

There are 4 cats IIRC. The cats are high flow, no need to get rid of them. 2.25" is the diameter.

If the shop is re making the pipe, then no it doesn't matter if it is center in on a si/do. I believe thats the only way you cant get a si/do as i've never seen one offset in.

Pipe size is 2.25" unless you wanna do what I did and go back to the 2.5" pipe that comes out of the last cat.

Heres an offset in dual out flowmaster 50 series from jegs...I know its just a 2" out but its a 2.25" in. They have a 2.5" in 2.25" out as well offset.
Flowmaster 50 Series
