And this goes right back to what I was saying earlier about mufflers... a car should be as loud as possible. If the muffler does anything other than allow you to technically have a muffler for inspection, you've got the wrong muffler. Subtlety is overrated.

Seeing as you listen to 80's rock instead of Death Metal, I don't know where you get the idea...

Let me get this straight, it doesn't matter if it sounds like the Spice Girls gargling nails as long as it's loud enough?

How much do you know about proper exhaust design?

Well the thing is, from what I've seen, most mufflers that actually muffle something also smooth the sound. So not only is the car quieter, you're also getting a smoothed-out, less-aggressive version of what the engine actually sounds like, one that filters out choppiness at idle and quiets the backfiring when you lift off the throttle at high RPM.

Why would that be a good thing?

Why you no like Death Metal?

Not everyone wants a constant feed of what's going on under the hood. For a regular person, a quiet, muffled car that transmits minimal vibrations back into the cabin is perfect.

Oh, so you do like the sound of I4 with a fat fart can thrown on it.

Not exactly.

A proper loud exhuast replaces the stock muffler with one that doesn't really muffle, resulting in a much louder, more aggressive sound that actually sounds fast.

A fart can is just an echo chamber hung on the end of a tailpipe that re-amplifies the sound output from the stock muffler, resulting in the stereotypical sound of a Honda Civic EX automatic with Type-R badges stuck on trying desperately to exceed 30 MPH.

Most "fart can" exhausts do exactly what you claim. They typically take the place of any rear mufflers & do nothing but make a sound that gives the impression it's fast.

Besides, it doesn't matter since cars should be as loud as possible in your own words.

Shh. He can't hear you over his engine. It's powerful and loud enough to constantly move the goalposts.

You enjoy being wrong, don't you?

*breathes in*

Most standard mufflers are multi-chamber pieces that shuffle exhaust air around, making it lose energy. As it loses energy, it loses volume. Pretty simple, huh?

"Fart cans" and "proper exhausts" are simply perforated straight pipes that pass through sound chambers. Many cars come standard with these. Only they're called resonators, and they're typically installed mid-exhaust.

The perforations drain off sound energy and tune the sound, much as a flute tunes the tone of your otherwise toneless exhalations. That's why chamber length and width have a big effect on the resultant sound.

What makes some mufflers "fart cans" is the lack of glass pack or other sound deadening material, which means they do a terrible job of muffling.

In other words, some exhausts you deride as "fart cans" are actually louder and purer in mechanical sound than those "proper loud exhausts", which are tuned extensively and meticulously for sound production.

Ergo: a "proper loud exhaust" is a more "fake" sound than a "fart can" or straight pipe. You should hate it immensely, but consistency is boring, isn't it?

-

To tie this in to the Jaguar F-Type, that isn't natural sound. Neither is the E63. Both have exhaust notes tuned by meticulous acoustic engineering. The snap crackle and pop doesn't come from "proper exhaust", either. It's done by tuning the engine so that when you lift the throttle, the ECU retards the ignition and dumps a little extra fuel, so that the burn happens late enough for the flames to still be burning when they get to the muffler. (I've done this myself).

Which is even more "fake" than a car that sounds smooth and normal with a straight pipe exhaust. It's all pretentious fakery, really. I don't mind it... but the question is... do you? :lol:
 
TBH, my main reason for posting that in the first place was some people complaining that the F-Type was sounded too loud and aggressive. If a car is quiet enough to be sold legally, it's not too loud or aggressive.

To figure out the fart can vs. glass pack thing, I'd have to know the typical stock exhaust setup of a four-cylinder compact or midsize car. If they have both mid and rear mufflers, that could explain a lot (I've heard Cherry Bombed I4's on YouTube, and I've heard the ones that just have the watermelon-sized exhaust tips, and those sound lower and smoother, but also significantly more horrible, as if the sound is still running through a normal muffler, becoming smoothed out in the process, before being pumped back to full volume by the echo chamber at the end).
 
The mid-pipe units aren't mufflers. They're simple resonators. They typically aren't glass-packed (you can replace them with aftermarket parts that are), and have very little effect (sometimes no effect) on power production. They're usually there simply to tune out the godawful tinny resonance you get with a straight pipe.

Sound ain't power. The Jaguar F-Type could be much quieter without losing any power. It could also be twice as loud without gaining any. Modern exhaust design and computer-controlled engines mean that buying anything beyond the cat is for entertainment purposes only. The only modification behind the motor that makes any sense from a power perspective is an exhaust header or a turbocharger. A turbo is the ultimate muffler. It takes all that useless, stupid sound and turns it into power. :D

And, as mentioned earlier in this thread, Youtube is an absolutely sucktacular source for car sounds.

So, what you want is every car to be sold without an exhaust then, dumping everything right out of the block. I'm not sure you realize just how loud that is.



It would be like commuting to work every day in a Nascar race.
 
The only engines that sound good open are V8s. Everything else sounds terrible without some sort of exhaust system.

I wouldn't mind being know as that guy though haha.

That doesn't make any sense. Firing order, RPM, crank-type, displacement, and induction method will all have a dramatic effect on the sound of an open engine. You're basically just waving a flag that says "I'm biased towards V8's!"

Well it's almost internationally known that Slash + V8 equals unmatched love that can't be broken.

I'm sorry, are you purposely trying to become W&N's protege? You've made a lot of posts lately that borderline on his thinking that personal opinion reigns over all.

Be whatever you want to be, like whatever you're going to like. Just be aware that people here are going to ask you why and having a good answer is a better way to make friends than spewing BS.
