coming in this thread to state, i have a stock intake box, gutted cats, no muffler, and i noticed no increase in power, maybe a little more mid range, but, it sure does sound nice on the highway

and this is what happens when supa asks for a cell phone quality video of my exhaust, stock exhaust manifold, both cats gutted, with nothing but the oem resonator, sounds like poop, cant wait to throw my 3 chamber on there and some 2.5" or 2.25" piping

http://www.youtube.com/watch?v=FilgXr0RmYc - somewhat quick accelation, like quarter throttle, windows up, ac on 3.
http://www.youtube.com/watch?v=DtFxacZLYoE - both front windows down, giving it half throttle from a slow roll
http://www.youtube.com/watch?v=cEKGRWW4jsI - what i deal with every day from a cold start with the factory heat shields, its from 1500-1800 rpm and then it stops. dat brown note

omg dennis does not know hot to focus on an iphone

You said it sounds like poop but in the post above you said it sounds great on the highway?

it does imo, it only sounds ok when i get on it

cutting the muffler will increase the flow of exaust by a little bit. you still have pretty narrow pipes coming from the engine. When i changed my exaust, i felt like i could pass people on the highway easier. but i wasnt able to go back to stock exaust and compare again. less restriction will give you less back pressure, which means less low end torque. so, probably better fuel economy on highway, and slightly worse in the city. if the muffler alone is enough to do anything.

as for how it sounds, mine sounded obnoxious at 2k rpm. idle was a nice rumble. it is possible that being in florida, my car had less restrictive cats on it than a state with annual inspections. ive never had a car in one of those states so i dont know. all i really know is that california would hate my mustang.

just got my muffler removed and pipe w/ turndown installed. sounds horrible at idle and from 1000-2500. after 2500 it sounds fine and I can hear my intake over it more, so its not that loud. I am going to buy a "turbo" style muffler to quiet it down more.
