i have the magnaflow axle back exhaust right now but it sounds like a rice burner to me. i ordered the dynomax rockcrawler and was wondering if anyone has heard both. Really wanting to know if the dynomax will be deeper and sound tougher. its a calculated risk with having already purchased it but i would like some input if anyone has some.

 

I have the Dynomax, definitely got deeper as it broke in.

 

I love the Dynomax - I dumped mine at the axle and its a great setup...

BR-

 

How many miles before you think it's broken in? I installed mine last weekend. Probably put 120 miles on it so far and have noticed a change in sound. Curious how much more it will change.

 

My dynomax hits my rear track bar :(

 

Easy fix, have the exhaust exit infront of the axle You can just barely see on mine in the photo, it only extends about 8" beyond the muffler.

 

Mine seems to have settled in now with around 500 or so miles on the exhaust

 

I got the rancho "off road" exhaust that came w/ a dynomax muffler, had that changed to a magnaflow muffler because it was too loud and droned like hell to boot.
Still too loud; just a pain to listen to driving around, I'll probably be changing the magnaflow for a quieter muffler still.
The dynomax muffler that came w/ the rancho exhaust also rested right up against the frame; not good; no way to really move it using just the parts that came with it; it bolts up to the system behind the cats.
When they put the new muffler on they welded it and moved it a bit so it didn't hit anything.
