One thing though. Pushrods4ever did say that his hearing was impaired after each run for a period of time. That is an almost SURE sign of permanent hearing damage, I'm afraid.
I am very senstive to that right now for reasons that a few of you know about. DON'T hurt your hearing - you won't realize how important it is until you lose some of it. And, the losses tend to be frequency specific sometimes,which fools you because you think you are hearing everyhting the same, but you lose many of the subtle frequencies important to understanding spoken language.
This does not mean you can't use exhaust cutouts. Just wear earplugs or earmuffs when you do. There are even sophsiticated earmuffs with dual (stereo) amplifiers that filter out ONLY sounds that are loud enough t be harmful, and leave the rest alone. With these, you can also AMPLIFY the "non-harmful" sounds, so that someone's whisper quite a distance away can be heard. Dillon (shooting accessory and reloading equipment supplier) makes a good set that I ahve used for years.
It is obvious to us and others that we agree on very little, but I will agree that (another post of yours that several of dyno results are pure Bulls**t. These results are used to hoodwink, people who do not understand that there are many con-men out there that will do anything to steal your money. That is way I went to Florida twice to deal directly with Superchips and only let their aces touch my "Baby". Anyway, I can not agree with your statement that a 3" cutout with be nothing but a New Years Noise Maker. A larger C.I. Engine without the multi valves of 261 C.I. Supercharged Engine, I feel strongly would gain "Worth the Money" Horsepower and Torque from such a Mod. The problem with the small C.I. with Supercharger or Turbo is that you gain lots of RWHP but RWTQ. i.e. me with 412 RWHP and ONLY 383 RWTQ. Considering what was spent, and what was gained other than Loud Pedal, I would feel is well worth the bucks. I plan to install a X pipe behind the cats and Dual Electic Cutouts and true dual exhaust. Please understand that with the Mustang I spent less than $600 bucks to go from 348 RWHP (which a 380-390 HP engine should net on a dyno and I was on two of the them) to 412 RWHP.JimGnitecki said:You are taslking about an 03 Mustang SVT Cobra, the one with the factory blower, right?
I can believe that on a BLOWN, SMALL displacement engine (4.6 liters) that makes 390 hp STOCK, relieving exhaust back opressure would dramatically increase flow. The torque peak on that engine was at only 3500 rpm stock, while supercharged peak power was at 6000 rpm, indicating a WHALE of a cork somewhere in the system. I guess the exhaust was the cork! That was a VERY special case. In fact, that's one of those cases where a catback exhast that normally gives zero hp (but nice sound) to a max of 10 hp could actually deliver much more, just because it is addressing the specific "cork" in the system. See my book Chapters 12, 15, and 16 for more on this.
On a non-supercharged, 6.0 liter engine, I don't think it would be anywhere near that effective.
