Flowmaster muffler

I am sorry to post this. I tried searching and couldn't find the answer. I am wanting to get a Flowmaster super 44 muffler for my 07 with the 4.7. I cannot seem to find the inlet outlet size I need. Can anyone help? Thanks in advance

You may end up with nasty drone with that muffler unless you add a resonator. I'd suggest a 3-chamber Flowmaster such as the Super 50 instead. PM me if you'd like pricing and information.

I believe the size is 2.75" but a 3" will work. Take kolak's advice on the drone. It can be really bad.

I would recommend one of our Super 50 Series mufflers for your WK. Let me know if you have any questions.

The WK exhaust is a a metric size and what works best is a 3" inlet/outlet muffler. A muffler shop simply expands the tubing slightly so it fits snug inside the muffler pipe nipples and then welds a bead around it.

Either the Super 50 or the 70 are good choices.

I have the super 44 on my 5.7 hemi with my resonator removed. I personally love the sound.

Kolak is right though, it does have some drone on freeway cruising, especially when the hemi mds kicks in. I don't really mind the drone though.......... But I'm used to carpooling in my brothers JK, with JBA shorty headers, a cat back, with no top or doors, rolling at 75mph on 35" Nitto Mud grapplers. You want to talk about highway noise..... Holy cow that jeep is loud. Even my hemi with the super 44 and no resonator sounds quiet compared to driving in his.

Thanks everyone. I think I'll go with the 50 from Kolak when I get it back from shop when they figure out what's wrong with my 4wd low

I believe I have. I had them doing a bunch of stuff to my tranny when I had hard dowbshifting issues, still do. This was about 6 month's ago. I'm assuming they did it since they flashed a bunch of stuff. Hoping they have an update of that's what caused the issue.
