There are 2 reasons for replacing the factory BAZOOKA.
1- More/different noise.
2- Weight savings.
Modifying it doesn't save much weight as it's a behemoth.

There are a few aftermarket mufflers out there that don't increase the noise level much but give it a nicer tone.
I initially had a 2 Bros on mine, but it was just too loud for long runs on the motorways.
I replaced it with a Remus Hexacone that I got used from someone who sold their C14 and that has the perfect level and tone for me.
Has a nice burble at idle, a nice sound up to 5000rpm and only starts to scream above 5000rpm.
So, it's mostly quiet but you know it's running without looking at the Tacho!  :thumbs:

I wonder if you could’ve put the decibel killer on that 2 Bros.  Without it, mine was too loud but after putting on the dB killer, it brought it down to a more reasonable level, until I wind it up, of course!  Sounds gooooood!

It had the standard baffle in it. I tried without but that was WAAAY too loud.
It also popped and banged on the overrun which the Remus doesn't.
It was an early 2Bros Titanium that I bought used from someone on the COG forum.
I still have it in the garage alongside the OEM Bazooka.



Below is a pic of the C14 as she is now with the Remus Hexacone.

On my C10 I have the Delkevic 18" mufflers and in those I have had to stuff some stainless steel Scourers to mute them as well as running the longer baffles.
Too many aftermarket systems are just too loud and many have a nasty drone at highway speeds.
In the rush to make them cheap the testing seems to be missed out.

Personally when I hear a loud car/bike go past I just think "asshole".
OTOH when I hear a nice sounding car/bike go past I think "nice" and give the thumbs up.

I'm the same way. I like sound but not loud/obnoxious sound.
I tied a couple of different Slip-On's and wasn't satisfied until I went to a pair of Area p Slip-On's.
I like them the best. Nice sound...

Ride safe, Ted

i'ma dick, yes, and I have modified the '08 spud, to make it lighter, smaller, more robust in sound, and completely within epa std's. as stamped on the housing.. took 6" out of the frontal area, after grinding the weld off the back half under the aluminum cover, a and pulling the "guts out".. then chopped off  the forward 6" including the block off plate, and trimming the associated rear, to profile, an welding all back together.. nice sound, not obnoxious, perfect in every way.. free... hear that NO MONey$$$$$. and very happy.. toss a bunch of money out, to buy an exhaust, that as sold was never ever tuned specifically for the ZG1400.. only sold as "will work  don't be a sheep,and buy an an exhaust, neverr designed specifically for your bike do whatever you want, but be wise. and understand the differences between all the bike, and performance features associated you guys want to know how to mod the spud.. let me know.. I have a welder, and everything to mod it..

after
 In retrospect, buy a NEW Kawasiki Z bike, and deal with dual sided fugyl big, huge, fugluy muffies.. .. damn, we always wanted a single exhaust on the C10.. Kaw listened, made it happen on the C14... then everyone wanted to mount dual cans on it.. the stock pipe, and muff weighs 21#.. wtf. I shucked off 4 pounds, on my mod.. and its quiet at moderate rpm, and comes alive, when pressed in conjunction with my MRP flash.. meh.. spend your money folks. my mods were a simple beer drinking afternoon.. done deal.

yeah, us with major engineering degrees don't know squat.. go watch som more you tube vids.. that seems to be the "new education".  (drops mic... over and out)

I didn't want to go the aftermarket route because I felt the more affordable cans looked like something that was slapped on, an afterthought,  (unless I spent $900+ on a high end can), so I went to Lowes and bought 2 long drill extensions and a 1 1/8" hole saw and drilled the snot out of it through the back end.  Believe it or not, it gave me just enough extra growl at cruise to feel good about having a 1400 cc engine, and when I get on it, it actually sounds pretty good! Not loud, but present, if you know what I mean? Instead of the previous stock "wooosh" now I get a nice "GrrrrrRRRRR" Only downside is a few blips and pops on decel. It "feels" like there's more power, but that's probably more the Shoudaben tune.  Funny, before drilling, there was a spot in the 1200-1500 rpm range that would fluctuate and surge. After drilling, it's barely noticable...go figure... :o

So, in the end, I figured, not hard, inexpensive, and if it didn't work, I could either buy a nice aftermarket or pick up one of the OEM's everyone has taken off...how could I lose!

BTW - Love the "Engineering vs YouTube vids" comment, MOB. Spot on. For that matter, I've been turning wrenches for over 40 years, and 25-30 year olds still think they know more 'cause they "Googled it"...hillarious... ::)
I never ride alone...my Lord and Savior is always with me.

Yeah, but you can mount an amp and speaker and use one of the programmable noise makers that some car manufacturers use.  :rotflmao:
I think I'd make mine sound like a Lamborghini V10 that can rev to 10500rpm  :thumbs:
By the time the motorcycle manufacturers manage to produce an electric bike that has decent range and fast charging I'll be incapable of riding or dead so it's somebody else's problem.  :popcorn:

Yeah- I wonder if they will require that on motorcycles, too (some type of artificial sound at low speed).

Well, that sounds perfectly depressing!  Oh, you have to add- with at least the same performance and also affordable.  Hmm, now you have me wondering if *I* will have the longevity...

Sorry Max  :chugbeer:
I've been hearing about electric cars and motorcycles since the late 80s as a friend of mine was addicted to electric conversions back when Li-ion batteries were a fantasy and electric cars used deep cycle lead-acid batteries so they all weighed a ****ing ton!
Ranges were pathetic and performance severely lacking.

The newer electric cars and bikes are now getting there and the performance is already there if the Isle of Man TT-Zero is anything to go by (176Mph peak last year) but they do need to fix the range, charge time, and of course cost.
Cost will be fixed with mass production but they need to at least get close to current range/refuel times for those numbers to go up.

Me, I'm probably gonna buy me another low mileage C10 as my 198k mile '89 is turning into an "eternal broom" and I'm reaching the stage where I no longer want to be spending every weekend in the garage keeping it running.
Gonna keep the C14 until I can no longer ride or one of us dies.  :rotflmao:
