I'm torn between the cheap Thrush muffler or the Flowmaster Series 50. Anyone know which model I need for my 3.7 WK? What diameter inlets and where they are located?

2.5 inch....offset inlet, center outlet. I'm not sure how the 50 series will sound on your 3.7 liter. Sounds amazing on my 4.7...

I'm starting to think that the investment into a Flowmaster or Dynamax probably isn't worth it on the weak little 3.7. Might just go with the Thrush. I've regretted buying the 3.7 ever since day one.
Why do u regret buying it. What are you trying to do? There is more then u think out for the 3.7 liter now. You can get shorty headers....cold air intake...performance tune...3.73 gears.....4 low....just saying

granted the XK is heavier... The only regret I have about the 3.7 is that it didnt come with 4lo... But the fact that I can fix that now makes it so much better.
That and you can regear to 3.73's! If only someone made 4.10's for the front diff!!!!!Originally Posted by AJeepZJ
