I don't know about cuttin the muffler and leaving the cat but the PO cut the cat off and left the stock muffler on my jeep and its a little louder than stock but has a helluva better note to it so im just gonna leave it the way it is. But I live in a small town in Texas where they dont do emissions checks. :beers:

I have a dynomax cat back system on mine and the drone will get to you.  It is not holding up great either.  It already is rusting though.  It might be replaced with something else soon.

Speaking of droning. When I had my Jacobs ignition, I'd get a awful drone when I held the throttle at 3500-4000RPM and it would resonate inside the Jeep.  When I went with the PD Firepower it stopped.  The engine smoothed out over the whole RPM range.

that's one thing the vortex muffler seemed to eliminate was the highway drone you can hear it cause it's louder then stock but not annoying hard on the ears drone.  it's only loud if you are hard on it and revving it out.  idle and low rpm is fine.

and I"m running a pacesetter header and fake cat

I had a cherry bomb on my s-10 4cyc years ago.  Practically no muffler.  For one, everyone thought I was going to race them.  Two, I agree the sounds gets on your nerves.  Lastly, I seemed to get pulled over more often even when I was driving sainly.

the typical red cherry bomb?  mine is a actually muffler not the red one but it's still very free flowing but does a much better job then the red one

How loud is the Cherry bomb muffler? It looks like a regular muffler right? Not the red straight thru glass pack.

it's straight thru and louder than a full size glass pack.

I was thinking of the Pro or Turbo. http://www.cherrybomb.com/products/
I now realize he was talking of the glasspack, straight thru design.

Funny thing is the Borla is practically straight through as well.  My old one had the centered output so you could see right through it.  The new one, like my original is offset but you can still see light.  They both sounded the same.

this is mine

I more picked it up because it is a sold case muffler and wouldn't fall apart like the aluminum stock ones would after 6months to a year. this one has been on for a while now and has taking a huge beating!! got it more for durability vs quiet but I actually like the sound it made

it's got a good sound but no drone at highway speeds.

has a nice sound but can get loud when your reving it out!  but nothing near like the glass pack. I have had lots of good complements on how my jeep sounds most think it's a v8.  we had guys up from London and I went to put in washer fluid and he ran to see what motor I had and was puzzled it was a 4cld lol I then told him I have the big intake and header and high flow exhaust.  and all they can say is wow it sounds great I was sure you had a small V8 in it!!

the glass pack more like running nothing but a resonator/ spark arrester !!!

is it stainless? how much and where did you buy it from? thanks in advance.

btw, anyone recommending a high flow cat that is CARB/Smog approved or that will pass emissions?

Magnaflow/Car-Sound.  It costs $200 though.  $100 more then the 49-state.  I have to buy one soon so I can smog my Jeep.

You can get them a lot cheaper off ebay.  I paid under $50 for my 49 state version.  Looks like the CARB legal part is 39005 (universal fit)  $144
