Hi,

currently I have the magnaflow magnapack exhaust on my car and it sounds great. I was looking into getting an offroad h-pipe or the mac prochamber offroad pipe. I dont want to do x-pipe because I dont want that raspy sound. How much louder is my exhaust going to be without cats? I dont care how loud it is outside but dont want toloose my hearing inside the car. Also is there any side affect or danger to the engine or computer by running no cats?

Thanks for any info

Car is a 2007 GT

Drone is not too bad unless you have an auto. Alot louder, (Don't blast past Cops) Definitely old school sounds though.
You'll have install MIL eliminators ($70-80) on the aft O2 sensors or buy a Tuner and turn them completely off.

Is it going to do any harm to the engine turning the back o2 sensors off? Would it run extra lean or rich? I guess if I go on a long highway trip I could always put the factory cats back on if the drone is too bad. But I want a little more of that old school muscle car sound and I think this might be the way to go.

No the aft sensors are just for CEL on the converters operation, the fwd O2s are for rich/lean feedback.

Does anyone have sound clips of there offroad pipes with magnapacks, borla stingers, or any other comparable muffler?
