Is there a "close to stock" sounding pipe I can get for my 2014 ZX14-R? I enjoy the quiet but hate the bulk and look of the factory pipes. I'm into more quiet than loud but would prefer something in-between, but for sure on the more quiet side. Most people would think it's a waste of money to buy another set of pipes only to have the same thing...but for me, it's the opposite. I'll invest more money to get exactly what I want.

I had M4 drag pipes on it and hated the noise, sold the pipes and am now back to stock. LOL!

That's gonna be a tall order. The reason the stockers are so big is to be able to support the power while being quiet. You need a lot of volume.

Yoshimura R-77 slip ons with sound baffle inserts installed. They are louder than stock but not obnoxious. I have them on my bike. Nice low rumble.

I got Delkevic Carbon cans. They said their Baffles reduces the noise level to OEM stock of 80dbls. Take out Baffles and it is 94dbls. My new cans with mid pipe weighed 6.5lb each. Delkevic has all sorts of mufflers to choose from.

I have the the Yoshi R-77 also, with the baffle in they are normal level just a bit "meaner" sounding than stock and I think they look great on the BBW

Thank you! I'll consider both of those mentioned. I appreciate the help!

How much power and weight do we gain/loose respectively?

No power gain-need a reflash for that.
My 2012 Stock Muffler weighed 17.5lb each. The Catalytic converters are housed inside.
Delkevic 6.5lb each; dropped 22lb.
I keep copies of old magazines and complied this information.
No one complained about the weight of a ZX-11 in 1990.

I can echo doubleD's favourable comments on the Delkevic carbon fiber slip-ons, which you can buy in various lengths. I bought their slip-on kit with their longest CF mufflers, and love it!

- Quiet whether the baffles are in or out - just a bit louder with the baffles out, but definitely not annoying to anyone

- The carbon fiber mufflers NEVER get hot on their exterior, only warm, so you can cover the bike right after a ride without waiting for mufflers to cool, and if a saddlebag were to contact a muffler, no burns

- WAY smaller and far lighter than the OEM mufflers. doubleD's comparative weights are right on

- The weight reduction has a dramtically favourable effect on the bike's handling and also its maneouverability in the garage or driveway, because the OEM muffler weight is BOTH HIGH and WIDE

And yes, any performance increase would require an ECU tune or Power Commander,because while the slip-ons might flow some more air, the stock computer does not know that without a tune or a Power Commander.

I have the Delkevic 14" CF Oval slip ons, and they are pretty quiet and look perfect. They are to quiet with the baffles in. My son put the 4 into 1 with 9" CF muffler on his new Z900 and that's quite a bit louder.

I opted for the Akropovic slip-ons and I have chosen to leave the tip inserts installed. I rode with them both in and out and to me they're simply too loud with them out.

The slip-ons are very expensive but they are nicely made. I have a center stand on my bike and the Akropovic came with the correctly located stop which made them a simple bolt-on installation.

I ended up ordering the Dels direct at a great price and also bought their extra quiet baffles so I'll continue with my "stealth" riding and enjoy the new pipes in all their glory. I went for the aluminum oval for that classic old school look to contrast with the awesome paint scheme of my 2014 Green and Black. This is my second attempt to get rid of the extra baggage ugly stockers and I didn't want to make another mistake.

The first time I bought M4 drag pipes and absolutely hated the noise. The bike felt like an old worn out piece of junk. To be honest, I am SIXTY SIX and a half fuckin years O L D....so ITS TOO LOUD for me!!!!!! L O fuckin L

Hey guys
Just wondering of all the guys running slip ons etc. How often do you have to repack? Are the re pack kits easy to get? I too would like to ditch the stock mufflers, but the extra work in re packing and getting the kits is what holds me back. That plus the "attention" of the police around here....

Fordtech: I cannot answer the question about repacking, as my Delkevics are only a couple months old. But as for attracting police attention, that won't happen with the Delkevic slip-ons. I swear they cannot be much louder, if any, than the OEM mufflers, and that's even with or withOUT the (included) Delkevic baffles! It's a sweet setup.

One more here for the Yoshi R77's.
IMO a great balance of weight saving, looks and just the right sound.
(I have my baffles out and it still isn't offensive noise wise)...

Ive yet to hear any after market pipes/slipons that are as quiet at the OEMs. The opinion of wether the exhaust noise is not too loud or annoying or “offensive” is a subjective one. To many non motorcyclists, most bikes are too loud straight out of the box before you even start tnkering around with exhaust and induction mods. Personally I would prefer the stockers to be even quieter. Thats a big plus for electric bikes IMO but everyone has their own tastes of course.

I have to say that I am very excited now. After that horrible experience with M4 pipes, which I hated and quickly removed from the bike and sold on ebay, I was very reluctant to try slip-ons again.

But with the excellent advice I got on this forum I took another chance. The Dels are perfect. I got the shiny finish oval long ones and the optional extra long quiet baffle. The sound is exactly as stock, with a hint of roar which I totally LOVE. This really tops off a wonderful machine and inspires me to ride it much more now.

So what Dels did you get? I have my stock "trash cans" still only because I too like quiet bikes. I don't want to wake up and annoy my nice neighbors at 4am and I don't want to attract attention from cops or anyone else.
I also want to make enough room for luggage mounts.
Thanks

Nordicwargod: I have the Delkevic Carbon Fiber dual muffler system, with the longest CF mufflers they offer, and LOVE the system:

It took a bunch of weight off, and that weight in the stock mufflers was very poorly mounted - very high and very wide - which hurt the bike's handling and also made it very hard to push it along a driveway on foot.

It is supposedly a bit louder than stock, but if so, it's sure not MUCH louder. It really won't annoy anyone.

It makes access to the chain for cleaning the chain MUCH easier.

It makes washing the rear wheel and rear portions of the chassis much easier.

It makes mounting aftermarket saddlebags much easier.

It will never corrode.

There's apparently a small power gain (Delkevic provides a dyno test and dyno graph on their British website), but I never run my bike hard enough to appreciate it.

It looks way, way better than the stock system.

The quality is very high.

And it is relatively inexpensive thanks to a favourable currency exchange rate with Britain.

It's a no-brainer easy solution for a lot of ZX-14R riders.

Thank you. I'm looking at the 18" carbon fiber oval's too! The stainless 18" are $100 less though. About a pound difference which does not matter to me. I assume the overall sound level is the same between the two. I like the carbon fiber set! I'm going with these; will pull the trigger soon.
Interesting and informative thread. Thanks to all. I'll post pictures when its all done.

Nordicwargod: The CF mufflers have one more important advantage, especially if you will be mounting luggage: they NEVER get hot. I am able to put the motorcycle cover on right after I finish a ride - no cooldown time needed. And I never worry about the mufflers burning my saddlebags.
