Why do you think it sounds like that because its not being pushed out of the engine smoothly and cant push the combustion all the way through that size diameter pipe for that long of a distance P.S. it's called BACKPRESSURE so if you want to be a stereotypical Honda and be called a rice burner because you make that nasty fart noise, then cool get the 3 inch exhaust, but if you want to sound like your actually making power and actually feel that power than I would go with no more than a 2n1/2 inch exhaust until you are pushing forced induction.
First, since you guys "heard" it on a drifting show, then it must be true, LOL... That's gotta be the funniest thing I've ever heard...
I mean no offense to you guys, but just watching some show on drifting is not going to explain the mechanics of the exhaust system...
Every car is different, so how could you possibly say that 2.5" is the BEST option for sport compacts?
Also, FYI, your theory about the 2.5" pipe is wrong... I'm not gonna rip on ya, but you need to understand the theory behind it... I have a 2.5" pipe AND I'm running boost
I'm telling you from experience, and from my education...
I know ALL about the technical aspects of fluid dynamics (fluid in this case is air) and the term backpressure, as I have an engineering degree...
LOL... No, Horsepower is NOT a "by-product" of torque (what does this mean anyway?)
HorsePOWER is a FUNCTION (mathematical equation) of torque. Consider the formula for HP, which was derived from calculus, and shows the relationship between TIME and FORCE. This is commonly called POWER (just as in electrical circuits, a light bulb for example, uses power, a force (emf or current) over a time increment)...
HP= (TQ*RPM)/5252 HP (force to move 1lb through 1 foot distance in time of 1 sec)
Most importantly, HP is dependent upon TIME AND FORCE (the only variables in the equation), not just force (which is what torque is, twisting force)... Ever wonder why you can "feel" torque but not Horsepower? Ever see a mustang owner wonder how in the hell you beat him in your 100 lbs of torque 1.6 liter? It's called efficiency
My advice is to pick up a book from the library it will give you TONS more knowledge than some TV show...
Finally, please don't just believe anything you hear on TV, cause chances are it's all about the advertising... They will "tell" you what is good, so you go buy it, get it?
