Flowmaster exhaust pls help

hey guys, i'm looking to put a muffler on my truck. nothing fancy just swap mufflers. what did you guys with flowmaster 40 series do to get the mufflers to fit. did you have to deal with adaptors or is there a flowmaster that has the 2 inch inlet/outlet. i searched summit racing and found only bigger inlet/outlet mufflers (2.5") can you please either post a link to a flowmaster that will work or if i have to play with stupid adaptors than i will. thanks for the help.

the stock pipe size of rangers is 2.25 in. I had to use adapters for my first exhaust system. It was a flowmaster 40 bought at advanced and some adapters. The mufflers are made to be welded so when it says theyre 2.5 in that means they will line up perfectly with a 2.5 pipe not slip just inside of over top of it...

I didnt have to use adapters but i did have to weld on about 6" of extra pipe
you want an offset in centre out. 2" is # 942043 2.25" is # 942443 for the 40 series delta flow

perhaps my year was different? i have a 02 and i measured right before the muffler and right after and it was 2". the flared tailpipe is 2.25" o.d. so i should order the 2.25 or the 2.5" mufler not to restrict the pipe at all if i'm going to have to use adaptors correct??

oh yea thats rights mines an 02 also. I would order the 2.5in cause you can buy 2.5in to 2in adapter at any local auto parts store for like $10. 2.25in are far less common. If I was you I would just get a whole new exhaust system though...welded together and everything at a local shop. Do the flowmaster si/so and have it exit right before the rear tire. Thats what I did and it was only $100 and considering the muffler alone was $70 I would say thats the most satisfying way to go

wow thats an amazing price! unfortunatly laws in mass are extremely tough with modifying anything. i could get pulled over for my 3" body lift if they really wanted. i dont want an obnoxious sounding vehicle to attract any added attention. if this wasnt my daily driver i'd be kicking myself in the *** but i'm going to play it safe.
