Who has what and how do you like it?
Im ready to upgrade from stock and reposition it in front of the rear axel.

Any other ideas for upgrades to be done at that time?

i'm interested in this as well. I'm still trying to figure out why the stock muffler is the size of a water heater.

 

EPA Emissions

 

This kit only fits Unlimiteds, I believe. I had a Flowmaster with one in/two out installed, so it looks like duals. It sounds great idling and good driving. This pic is from below; the muffler doesn't show as much when level.

 

I have flowmaster 50 series Delta flow, in stock location. Sounds great, and no drone on highway driving. I'll try to take some pic later on

 

Im kinda new to the world of jeeps and rigs and well everything. Slowly learning.

What does a muffler do for you? I know it makes a nice pretty hum. My husband had a flowmaster on his old diesel F350.

Why would one say they are pointless? my husband said they were for jeeps. Just curious.

 

I read through the entire thread but its only about Cool Tech/Magnaflo.

Im really looking for feedback from people that have different mufflers and how they like them.

Im probably going to have a speedshop do my entire exaust in SST.

 

You have a speedshop! Well I should have just gone to you when I changed my exhaust!I live in Draper! I changed to the cool tech and it's not bad. I love that I moved it up between the frame rails and out from the back where it would have been damaged just like my YJ's. We will have to go wheelin!!

 

So BIM6180, the 50's series a bit quieter than the 40's series right? Did you get the "delta flow" version. I'm still kinda curious about the different flowmasters. I know i ran a si/so flowmaster 40 on my f-150 dumped under the bed and it droned pretty bad, but sounded awesome. I'm ok with a bit of drone (like when downshifting to slowdown) but would prefer no drone at 65mph.
