I borrowed an RGVr 250 for quite a while years ago and it had race pipes/chambers and a dry clutch, was raspy and rattly sounding and pissed people off! I loved it! Smelled good too!

I hate loud pipes. They fatigue you when you're riding and they annoy almost everyone else. Talk about putting a gun to our own heads.

Cue "loud pipes save lives" spouting $hite. When pootling along in my car I've NEVER heard a bike coming up behind me until it's basically passing me. Unfortunately the exhaust is at the back of a bike.

I agree. Back in the day it way ok... my Escort leaked so much of everything you could anything... newish Jap car, not much chance, and even less if the stereo is on.

Yeah, sometimes when the bikes pass me the pipes are so loud I make spelling mistakes when texting, lose the paragraph of the newspaper I'm reading or drop my PDA's stylus

Loud pipes get on my nerves, I get enough loud at work. I have to admit to me it seems to be the cruisers that tend to be loudest, and most annoying. Mild is fine, wild pipes are for self indulgent dickheads who are old enough to know better

my xr650 motard is embarrassingly loud, sounds fantastic but i know you can hear it for well over half kilometer in cbd ( not counting all the car alarms going off arround me ) and in the valeys out west well everyone hears me comming 5min before i arrive ( and no my bike isn't really slow ) but i dont need to atract any more police to pick up more speeding tickets !! if i could work out how to tame the sound with out spending heaps and with out lossing too much power i would jump at it ....

saying that a well tuned soprts bike with a hot pipe is always music to my ears

Both of my bikes had aftermarket exhausts when I got them.

I think I'd rather the current one was quieter, simply because I don't like annoying the neighbours. I had the same problem with my old Celica - it was embarrassing if I'd been called in to work at 3am, then arrived home, uphill, in that. It set off alarms in parking buildings too.

Having said that - I do like the sound myself. Especially in tunnels ... it's a pity that most around here are in 50k areas, so there's not much chance to wind it up. And the biggest problem with the new Wellington Bypass is that there's now more fastish road before you get into the Terrace Tunnel, so you're usually doing at least 70 before you get to the entrance - again only 30k (well, ok, maybe 50 - 60 ...) to gain before you've got to button off. Assuming you're not stuck behind traffic that thinks 80 is the appropriate speed in there.

Summary? In the right conditions - yes, the Remus exhaust sounds quite nice

But I wouldn't buy one, and it wouldn't increase what I was prepared to pay for a bike.

Most of the boy racer cars are turbo'ed so the greater the pressure drop across the turbine (exhaust) side of the turbo the more boost is supplied to the intake and it will also come on fasetr (be less "laggy"). You will quite often see Log manifolds on a turbo car which on a N/A vehicle would create awful results with one pulse blocking the next. Turbos don't spin at the average gas speed as the pressurised gas speeds the wheel up more than the lack of gas slows it down. I hate to make up numbers but it would be closer to 70% of the average gas speed, this means having all the gasses in uneven lenght pipes coming into the turbo at one time makes the whole setup work better. What I hate is "performance" cars with massive chrome wheels! One of the heaviest metals out for more than some nice light OZ Racing magnesium rims, do they know about unsprung weight!

Interesting stuff (you'd get rep if I wasn't sin binned). Explains why turbo cars have big bores, and that people my age are wankers for putting big bores on their mazda familias

Mind you, I'm being a bit hypocritical cause my exhaust is pretty loud at the moment. I'll get some pink bats from the attic in the weekend

I remember riding in a car and looking back when I heard a large V-Twin rumbling. It was still 5 cars back, and it was deafening when it was right next to us. So in a car you are more aware they're around, but on the bike you won't have hearing for much longer

I personally prefer my V&H Straightshots, because I can filter through the motorway traffic and know that the majority of people can hear me. My filtering has become easier since the loud pipes have been installed.

Loud pipes don't save lives, but they make filtering easier and less stressful.

I guess this is all a matter of opinion. A few years back when I was living in London I did this http://www.bikesafe.co.uk/ because it was free. The cops that were running the course (believe it or not in the UK the cops are actually on the whole pretty pro bikes) actually advised us that aftermarket cans can help to make you more visible to the average idiot car driver and that they generally turn a blind eye to noisy cans, as long as you don't take the piss.

I actually dissagree???? Mabey im nuts.
While most slash cut jobs are not tuned ..... there are exceptions to the rule.
Moto GP has proved this, drag ways have proved this, speedway has proved this and the industrial sector (graders, diggers, rigs etc) have this tied to a T.
Sometimes flow is better than backpressure.
