the dynomax is too big & gets hit by the driveshaft during offroad use, any ideas ? thx.

 

I don't know how big your muffler is. Maybe some pictures? I have a flow master super 44 and it's tucked a little higher than factory, but it can take a good hit and keep on rolling. Basically another skid plate it's so thick.

 

Don't know if this will help but here are the OEM muffler dimensions:
oval shape
OAL- 24.5"
width - 9.75"
height - 4.5"
inlet - 2.25" center
outlet - 2.25" offset

 

thought about a FM had one on a cj once they are def. tough & can take some abuse. my dynomax is mashed up a bit.how loud is a 44 compared to stock , does it drone at hiway speed ?

 

thx for that info, this dynamax may be bigger , gotta check.

 

Mine is nice, it's louder but I can't really hear it over the other vehicle functions unless the windows are down. Mine is also dumped at the axle so it's a littler worse than yours would be with full exhaust

 

Generally speaking, smaller = louder. I don't know how big it is but I've heard people recommend the Walker Quiet-Flow if you want to keep it quiet.

 

Yep, I've been watching this thread hoping someone would have a decent answer but I think this is a want 3 pick 2 situation.

 

I used an oval magnaflow on mine. Smaller then stock and just a tad louder. You can barely even tell its got an aftermarket muffler. I can get a part number if needed.
