I have a 2006 Lincoln Mark LT and it's time for a new muffler, there is a small crack in the muffler on one of the weld lines. The previous owner put a Flomaster supper 44 cat back exhaust on before I got it and I had to alter the cats and turn them into test pipes almost a year ago. I am referring to my gutted cats as test pipes(trust me I know the difference). The cats started to go bad a year ago, so instead of replacing them ($$$) I had them gutted and welded back by my mechanic ($50 and took two hours).**my question is what muffler are you running with a similar combo/test pipe OR what muffler do you recommend with gutted cats/test pipes?

-Currently it sounds amazing besides the exhaust leak but it's honestly too loud, I was thinking about the Flowmaster 60 Series or the 50 Series. I want a noticeable rumble but nothing too crazy.

 

Forgot to add, I have a cold air intake as well

 

If you don't like a loud muffler, choose magnaflow. It has a nice deep tone.
