Mufflers for the 3.7L

I read a while back on here about somebody putting a 60 series flowmaster (i believe) on a 3.7L commander. Has anybody else done mods to the exhaust? If you have how is the sound? I'm looking for something with a decent sound for a 3.7L, not too loud but not too quiet. Before the smart remarks come, i know, i know, I should've gotten a HEMI.

That's right I forgot you had a different muffler on yours. Which flowmaster did you try?

I think it was the SUV but cant quite remember. Muffler City placed each one on the XK and held it in place while another employee started the XK and rev'd it so I could choose. I am sure they would do the same for you. Only down fall is your old muffler is cut off before you make your decision. But if you go down there talk to Al Jr. Good guy.

I've got the magnaflow on my 3.7, part number is MF-12256. No exhaust tip like AK, but it sounds good - not too loud, but enough rumble for us. I'll try to post video/audio tonight.

Can't wait. Where did you buy the muffler from? The exhaust should sound good with the CAI too. How do you like yours? I love my K&N 65.

I think I'm actually going to do it myself although the fact that they let you listen to them prior to welding it sounds very tempting. I like them loud but I have to keep in mind that the family rides in it too. I got the super 40 on my ranger but that would be way too loud for the commander.

I hear ya but for the money I spent it was worth it. Going to hit them up again after the Christmas bills and replace the muffler on my new XK.

I have never heard a Flowmaster on a Commander, but almost on any other truck/SUV, flowmaster makes them sound like a big ford 350. The sound is not deep, but very loud and acoustic if that makes any sense.

I hope the Magnaflow that bjamrow has does not sound like that.

I think the sound turned out good - given what I was working with, the 3.7...just enough rumble without being too loud in the cabin - kids and wife wouldn't have been too happy with that, well, the kids might have This is the first video I've posted, so I hope it works.
