This is probably a silly question, but the Barker exhaust came with a nut and a toothed washer. Where are those supposed to go?
<edit> Nevermind, I figured it out. I probably should have started installing the Barker before asking. It replaces the nut that is permanently attached to the stock muffler which secures the right side oil cooler mount. Duh!
<edit2> Thanks, Jornum!

It goes on the front right muffler bolt. You need to put it back but te nut is attached to the muffler |

The Barker exhaust's tip is really close to the rear tire--I'd say an inch of clearance at most. I don't think there is any chance of rubbing, but it's not quite as much clearance as I'd like. Jornum, I can't really tell from your pics, but how close was the muffler tip to your rear tire? I just want to make sure I didn't leave something out of adjustment. (Not sure how I would, but I figure it couldn't hurt to ask.)
Also, were you able to get the Barker's collector all the way onto the stock headers? I've got about 1/4 inch of space left on the headers where I can see that the stock exhaust covered. I tried all manner of rocking, tugging and pulling on the exhaust but that seemed to be about as close as I could get it. I don't think there is any chance of an exhaust leak, but I haven't fired the bike up yet since my little guy is asleep and I don't want to risk waking him up. Of course I probably couldn't even hear a leak over the clatter of the motor, so it's probably a moot point anyway. |

Mine has the same about an inch from the rear tire got 100 miles on it no issue.
I used a 2x4 just below the elbow to push mine up past the slots i had the clamps up to be sure.
Makes sure you have clearance to the crank case just need to see light there.
If not loosen the mount and push it down.
You can index the tip straight out if you want

That is a nice looking slip on.
About packing. I did not know about scrubble or whatever that stainless steel stuff is called years ago and I tried all sorts of stuff and nothing lasted very long on my Buell race exhaust for the X-1.
Worst was the perforated core rattling around inside the can: it would shear off the rivets from vibration and I went through dozens of front exhaust brackets. I am not exaggerating. I still have a half dozen ones I repaired (welded) in the parts drawer. I finally removed the perf core and had the can welded shut and the rivet holes filled in and that was the last time I had to replace a front bracket.
Damn nice exhaust. Do want. |

Flesh, I dont see how there is any chance of rubbing. I have about 100 miles on the pipe now and have not experienced any. I also went over some nasty pavement due to all the plowing this past winter. Gotta love Jersey!
It is close, but the pipe is offset to the right and points down and away from the tire. I know Tim said these were used on a race bike last year, so it does have some R&D on it.
I didnt have any issue with the install. When I did, I checked the best I could for leaks and could not find any. If you have any concerns I would suggest contacting Tim, he will be sure to help you out. |

OK I'm a little behind in my Barker install as I was away in Daytona when it arrived at the shop. Jay has done an excellent job with the audio and video work so I'll skip right past that and take care of some pictures.
My initial thoughts are this is a well made, light weight, loud exhaust.
I'll address each individually.
The weight or there lack of. For all that you see it does not weigh much at all. It weighs in at 6 pounds with hardware and mounting brackets. A stout 14 pounds lighter than the stock exhaust.

The quality. The welds are fantastic, the machining quality is excellent. There is a machined recess for the tip and for the optional quiet cores. There are two sets of drilled and tapped holes for the tip so you can "clock" it where you prefer. The clamp is a machined piece of aluminum that has been powder coated than back cut, nice touch. In my opinion the quality exceeds the price which is rarely the case.

Sound. As it has already been said, this exhaust at idle sounds like an Apache Helicopter. It looses some of its bark under throttle movement. Under load it may be different altogether, I could not tell with my helmet on.
For me the out of the box sound is to loud. I have tried both quiet cores that I have and I believe that something in the middle will be "just right" for me. The small core with spark arrestor has a very nice sound to it. Louder and deeper than stock, a touch quiet for my taste but noticeably different than stock. The larger core makes a difference in dampening the sound but not much. I suppose this would be the core for the person who wants to hear their exhaust! I fired the bike up without any tip or core and that is "The sound". Very big block sounding. The fact that the sound is tunable makes this exhaust a home run. There is no need to purchase multiple exhausts trying to achieve a desired sound. It can be done with this pipe.

Installation/fit. The exhaust fits tight to the bike, very tight. The collector does not install as far up on the header as the stock exhaust did. This is not an issue as the new pipe has plenty of overlap with a very tight fit.

pretty sure this is what I'll go with for the price, look, and quality, would like to see how it looks with side panels on... any body have pics.
Puzzled, great detail as usual, thanks |

Is the idle helicopter effect reduced at all with either of the quiet cores? That's the thing I dislike about my jardine. Is power noticeably affected with either insert? |

Yes the tone changes with the core inserts. Truth be told the idle is pretty dam cool. I'm currently running the larger insert and I can't tell any difference. I'd venture to say that the only way you'll see a difference is on the dyno. With that said it may just shift the power.} |

Some more input after a couple of hours of mixed riding. I have the larger insert installed currently. The sound changes as you would expect with RPM and speed. Over 75MPH and I can't hear anything other than the motor. Around town the exhaust makes some noise but not obnoxious. I don't know if it will set car alarms off or not. Just off of idle under 3K is the sweet spot for me as the sound is what I like. I ran around today without my ear plugs in which is unusual for me. I would think with my ear plugs in the larger core will be fine for me. |

Can anyone explain the concept behind the quiet core? It appears to be a smaller diameter pipe with mesh outlet.
I am not seeing how the smaller diameter pipe would affect sound. It makes some sense that the mesh will disperse soundwaves to some degree but I can't intuitively understand it being very effective.
Is the purpose of the smaller pipe just to accelerate exhaust gases in order to overcome any drag caused by the mesh? |

I just got my Barker a couple of days ago and installed it. I rode 60 miles (mostly interstate) with earplugs on under my helmet and thought the exhaust was pretty loud but within the tolerable range. Then I rode around town later without earplugs and decided that, yeah, this exhaust is LOUD.
I originally decided against the quiet core because I didn't think the exhaust would be anywhere near this loud. I had a Yosh 3/4 "race" system on my SV1000S and with its quiet core removed, it wasn't anywhere near close to as loud as the Barker exhaust is.
Don't get me wrong, I really like the sound and the quality of the muffler overall. I just got off the phone from ordering the quiet core from Barker. My advice--unless you are riding at a racetrack with no noise regulations, or unless you wear earplugs all the time, or unless you don't worry about irritating the neighbors, buy the quiet core when you order the exhaust. |

Hey Puzzled, it looks like you completely avoided getting any scratches on the muffler itself. When sliding the clamp over the muffler, I noticed that the metal on the clamp was scratching the surface of the muffler in a few spots. I pulled apart on the clamp while sliding it over the muffler but I still scratched it in a few places. It's no big deal since the scratches aren't noticeable unless you're right up to the exhaust, but how did you avoid the scratches? Did you just try really hard while prying the clamp open to keep it from touching the muffler? |

I inserted a screwdriver in the clamp and held it open while sliding the clamp on. |

Any impediment to free flow will reflect and attenuate the sound waves. |

Thefleshrocket I just spoke to Tim and he will be sending you a 1 1/2" insert. Let me know what you think of it.
I have a 1" and a 1 5/8" insert here and asked for a 1 1/2" also. That may be "the" sound I'm after. |

If you have any problems with scratching just use some green scotch bright rub with the grain and it will fix the scratch |

It is close at the front of the can, but it does not touch. It is tucked up under there very nicely. |

Puzzled, yup, Tim (didn't realize it was him that I was speaking to) said he had a "mid-range" quiet core that was not as quiet as the original quiet core but also didn't have as much of a negative effect on horsepower. I didn't ask what the change in horsepower would likely be because I *need* to quiet the exhaust down a little bit, regardless of horsepower changes. Of course, losing less power is better, and I will probably be good with a small decrease in noise level. Tim said that if the mid range quiet core wasn't quiet enough, he'd swap it for the quietest one. I'm sure it will be good, though.
Puzzled, you remember my order, where I added a line in the comments section saying I didn't need any silly quiet core? Yeah, silly me! LOL |

Yeah I chuckled when I saw that this evening going over orders. I'm going to keep all three cores here for those that want to hear the differnces between them. When I eventually get around to tuning the bike I'd like to try all 3 to see what they do. It is nice to have options. A tuneable exhaust is a sweet thing. |
