^^^^ Well first of all, those Damn Dodges are way freakin loud. Dont expect yours to sound like a 5.9. Besides, I think they only have 2 or even 1 cat, while you have 4.

Second, your setup is the medium for HP and sound. Its good for HP because its a SI/SO and its good for sound because its dumped. If you want something louder, try putting in a SI/DO FM40 exiting L style. That sounds awesome. And if you want it louder, swap in a 1 chamber IMCO. That will be louder than the latter. And if you really want to beat out yours friends little Ram take all the cats off(or install Hi flo cats) and do any of the above. Ill be damn if he wont be the one trying to get his truck to sound like urs

 

No, gutting cats is stupid and illegal. Where did I say anything else? What argument are you talking about?

Good quality after market high flow cats are available.

 

I am wnating to keep the performance of a Magnaflow, and also like the nice look of a polished stainless muffler. My local good exhaust shop suggested a true dual setup using a 14" DIDO magnaflow muffler and keeping my existing tailpipes. How would this sound compared to my current 18" SIDO, or something like a SIDO FM40?

 

I have JBA shorty headers, Magnaflow mids with hi-flow cats and a Magnaflow cat back, single muffler two in-two out. The sound is awesome. Loud while you wind it up and very healthy at cruising speeds. Unlike Flow Masters, they are not annoying or cheap sounding. They work for me.
