i have an 06 scab fx4 and im going to cut out my stock muffler and weld in a new one. correct me if im wrong but i think i need to get an offset to center with 2.5" in and out to slide over the stock 2.25" if im wrong let me know

 

The stock piping is 2.5" so you will need a 2.5" muffler, and then just weld them together. I cannot even remember what the old muffler looked like but I thought it was a single in/out. I would just go outside and crawl up under it and check it out.

 

ya its single in and out but inlet is off center and exit is center

 

****, I meant to say center exit/enter. I'm assuming you will be taking it to an exhaust shop anyway so I would tell them what type muffler you want and let them recomend which ones will fit in where the stock one did. Then go buy it off the internet for cheap and take it to them to put it on.

 

no im doing it myself and i looked under mine and its offset to center but i may just talk to a muffler shop to see what they say

 

actually i just looked under mine again and its offset offset but i think i could just about make anything work under there
