I am going to buy a muffler today and don't know the inlet and outlet diamater. If you know the sizes for a 2k dakota 2wd 2 door with 3.9 automatic please let me know. Haven't had time to take the old muffler off yet. Thanks ahead of time.

 

my 4.7l v8 had a 2.5" system

 

I'm thinking mine has 2 or 2.5 just at work right now and want to pick up a muffler after work. I'm gonna try the cherry bomb turbo and return it if i don't like it lol.

 

Stock is a 2.5 in and out

 

With your glasspack did you notice your mileage go up or down?

 

THanks for the help.

 

Sorry bro, I didn't see the question. My mileage stayed the same.
