Actually I looked a little closer add about $21 to that for shipping and handling. Its still a good deal IMHO. I cant even replace my flowmaster muffler alone for that.

I took my Dynomax off several years ago. I got tired of the noise and 6 cylinders just do not sound good with louder mufflers in my opinion. It just got annoying. It sounded really bad on deceleration.

I put one on two years ago...I like the sound, it's a bit of a rumble.

Looked nice all shiny and new...


Not to mention (but I will), it looked much better than the old....


It's still holding in there...I should have painted it before installing it, but I didn't.

I'd buy another.

Whistling 99% of the time is your air intake.

Everywhere I've looked it says the Dynomax 17309 is for 91 and later, 4.0 liter wranglers. Will it work on my 90 4.2 liter? Any mounting difficulties? What changed in 91 besides the size of the engine to cause the difference?

Thanks,
Aaron

The po installed a dynomax not but a couple of months before i bought it. Sounded nice at slower speeds but the drone at 55+ was unbearable. I ripped it off and installed a walker quietflow SS. Same manufacture and sound just much lower volume

If I remember correctly, the pipe/flange size is different...
