I removed mine completely.. one of the best mods I've done thus far.

 

The above is the best...

 

Not too sound like a tree huggin Prius driver, but the above mentioned is illegal and and extremely un-envirnmental.
To actually answer your question
JBA/HHP make a really nice bolt in high flow cat/midpipe.
Those are what I'm runnin, and IMO, the best exhaust mod I have done, not to mention NO CODES and legal

Illegal, yes! As for being bad for the environment... not in my experience. I lived in MD, had a friend that did MD emissions testing (dyno and sniffer), I was not running cats in my Impala SS at the time, and passed emissions, with flying colors. This was not an official emissions test (would have failed the visual inspection), just did it for grins and giggles, and it passed the sniffer with no cats.

I think the cats help on engines that are not kept in tune, and start running poorly after they get old, but a well tuned new engine, I would be wouldn't need them to pass federal or state emissions standards. Just a guess.

 

its not illegal in FL!

 

It is violation of federal law to remove a cat..regardless of state law.....and I have the Magnaflow Mids with hi-flow cats...only one I know of except for what comes with some headers..

 

i have flowmaster 40's/ what would you guys recommend i use?
im askin cause i wasnt my babie to sound like a beast!

 

I think your only choice is the Magnaflow mids unless something has just recently came out...My car got noticably louder when I installed them..HHP is a good vendor here to buy them from..

yeah i know....im talkin' about how theres no FL inspection like alot of other states. Alot of my friends run no cats down here & the po po dont enforce that law. I myself am savin up for the JBA cats......

TN is the same way...we have no inspections and nobody really cares if you got cats or not...

I'm running the JBA setup. I believe they are Magnaflow cats, and JBA mids.
Didnt really make my car louder per say, but a lot throatier

 

RandysWay, do you get a Malfunction Indicator Light with the cats not being there? Do you still have the 02 sensors (all four) installed?

 

My understanding is it is illegal to do anything with the factory installed cats. It is a federal violation to relocate, remove or replace the cats (unless they were damaged).

 

Yup - it's very naughty.

 

so are the magnaflow mid pipes illegal then?

 

They are if they remove, relocate, or replace the cats. (Unless the stock cats are damaged)

 

Booooooooo!!!!! Hisssssss!!!!!! Booooooo!!!! <<bushells of tomatoes being thrown>>

 

LOL, Sorry. For the record I would mod in a minute

 

i know this is an old thread but don't want to start up another one, but how many cats do the 07 Daytona chargers have? 2 or 4?
