An aftermarket exhaust system is at the top of most riderís mod list, but what can you really expect from that fancy pipe, and are stock exhausts all just junk anyway?

Short answer: If you're after power (and sound) boost for an otherwise stock bike, 100% worth it if you remap your fueling to accommodate the change.

For lame people like me, who like that quiet stock exhaust, not so worth it.

substantial weight savings is another good reason

I get the weight savings and many OEM's skimp on material quality to save money, but the trade-off, many aftermarket pipes can cause you to lose torque or power in lower rev ranges while gains are achieved in the upper revs.  Unless your bike sounds like a sewing machine stock (BMW R800GS) or the muffler interferes with foot-on-peg comfort (Kawasaki Z650), an afermarket pipe is purely an aesthetic choice and one might not gain any realized performance difference.  Of course, an aftermarket pipe can certainly make your bike sound better, you might get something that looks better, and could definitely gain some comfort especially for bikes with obnoxiously large OEM cans.

Carbon fiber exhausts are beautiful and also my yosh sounds bad ass compared to stock. Im also safer with an aftermarket exhaust, I've noticed and experienced when I'm driving I can hear a bikes exhaust coming from my rear before I can see it. So when sitting in traffic in a car once I hear an exhaust I'll move a little more to the left if I'm in the fast lane. Almost an aftermarket saves a few lbs too

Depends on what exhaust.  Some of them are just crap looking and even worst sounding.  Some of them are gorgeous and sound awesome.  The most important part of putting on an aftermarket exhaust is CHOOSING the right one for your bike, which requires some research, listening to sound clips, and choosing to be conscious of others around you.  There are simply way too many people who put on loud, obnoxious exhaust on their bike because they think it's bad-ass and they don't care if they sound horrible and annoy everyone.

Yep, I try to listen to some sounds clips of my bike with a pipe, look at dyno charts from reliable, third-party sources, and also research weight savings.  The Arrow pipes I installed on my Triumph shed 6 lbs from the stock cans.  The downside, with the stock tune the Speed Triple lost some mid-range power, and the bike felt off.  As soon as I downloaded a new fuel map, the bike sounded and ran better.  As for sound, not much louder than stock.  As for loud pipes savings lives, it more-or-less just annoys neighbors and not much else (https://www.revzilla.com/common-tread/stop-saying-loud-pipes-save-lives)...

My ZRX lost about 20 lbs with a full system and a jet kit with a +4 advancer I gained about 15 horsepower and did not loose torque. The stock system is double walled and very restrictive. A slip on would only gain a few horsepower so back when I did the mod it wasn't worth it. I must admit that as I have gotten older I wouldn't mind a little quieter system although I don't think mine is obnoxious by any means. My .02!  :45:
