Best buy for a R6

I am very happy I decided to buy this m4 mid pipe it's the best purchase I have made. The quality was A++ very good welds and it fit perfect without any extra work. Once I put the M4 slip on with it unleashed the beast it's so loud and sounds so mean! I am constantly being told that it sounds amazing and it's so loud! When I ride with my buddies it completely drowns there bikes out. I am very pleased with my ice . If you want to open up your bike this is what you need. You won't be disappointed at all!!!!!!

M4 Muffler Eliminator for Yamaha R6

This product has extraordinary build quality (VERY good welds), and fitment was perfect. It is slightly easier to install on the older models (2006), because at some point, Yamaha started welding on extra supports to the pipes in the newer models (2013), which need to be ground off after cutting the box off. You may want to source an older pipe on eBay to use for this project if you have a newer bike, or just take your time and grid down the welds. Once installed, it sheds a fair amount of weight (about 10 lbs or so), and gives much better airflow. I used it with the Akrapovic Megaphone slip-on, and it is loud, but not deafening due to a small amount of honeycomb material inside the pipes which help muffle the sound slightly. I would highly recommend removing the air pump assembly and using block off plates, in order to keep it from backfiring and popping on deceleration. Also, to get the most out of it, I would recommend a fuel management system such as the Power Commander V, and if you don't have access to a dyno, use their auto-tune kit with it.

This mid-pipe is an awesome exhaust upgrade, it opens up the exhaust and with a tune will add a few horsepower. The exhaust is a little raspier than before and pops sometimes when shifting and decelerating, but this should be expected when deleting a cat and muffler. I left my stock exhaust flap in and functioning along with my 02 sensor, no codes and the bike is running well, however I am getting the bike tuned with a PC3 this weekend to make the most of the mod. the install is not super easy and will require cutting and grinding some parts smooth to get the fit right with no leaks, I would also order oem header gaskets because the headers should be removed to install this. the welds and materials used appear to be top notch as well.

Excellent Quality product

The M4 midpipe is of the best quality and design I have seen. The bends are way smoother than any other brand I have seen. You can tell alot of time went into the design. The welds are excellent and is very sturdy. The install requires cutting of the stock header which can be done with a hacksaw but a sawzall or chopsaw would be the easier option. Well worth the time even if using a hacksaw. I have a graves slipon with it and it sounds great. Its louder and deeper than stock but not loud enough to need earplugs.

This is a Review on M4 Midpipe and M4 Slip-On

THIS IS A REVIEW ON BOTH MIDPIPE AND M4 SLIP-ON, CUZ YOU ARE PROB GONNA HAVE A SLIP-ON, MORE THEN LIKELY AN M4 IF YOU PURCHACE THERE MIDPIPE.... I have the M4 Slip-On connected to the M4 Mid-Pipe..Obviously you can go get a MUCH better slip-on out there that produces more power and torque..But if your not looking to get a Full Exhaust YET. I recomend not just getting the M4 Slip-On, cuz you will notice a very slight difference in sound and maybe a gain of 1HP..If you delete the cat with the M4 Mid-Pipe with it, you are saving about 12LBS, It sounds GREAT, and I gained 8HP on dyno and a TON of torque..But on a cool day with right conditions, you can gain up to 10HP!!!..Now with the Slip-On being $239 and the Mid-Pipe being $179..Your getting descent gains for $420..Not as much gains as you would with a full M4 exhaust..But about 75% of the gains a full system would give out BUT a full M4 system is $879-$900...And the Midpipe and Slip-On takes MINUTES to install, where a full system, you would maybe want to take to a mechanic to make sure everything is sealed 100%, but even if you did it yourself, your talking around 2 hours work.....LOL SO TO END MY RANT, IF YOUR LOOKING FOR DESCENT GAINS FOR LESS MONEY AND ALOT LESS AND EASIER LABOR, GET THE M4 SLIP-ON WITH THE M4 MIDPIPE!!!...ME PERSONALLY, I WOULDNT GET A SLIP-ON UNLESS YOU HAD A MID-PIPE, CUZ IF YOU DO THAT, YOUR JUST DOING IT FOR LOOKS, IT REALLY DOES HARDLY ANYTHING ASFAR AS PERFORMANCE AND YOU HARDLY HEAR MUCH OF A CHANGE IN TONE....."

What will happen if I install the m4 muffler eliminator kit but do not tune my bike with a power comander or something similar?

It most likely will not run correctly. For maximum performance a fuel programmer is recommended.

Once I installed it I felt a small amount of hesitation between shifts, and it will backfire alot when you let off the gas. You eventually will need a fuel management system or the ECU will need to be flashed to accommodate the free slowing exhaust.

Custom dyno tune or download tune from pc5?
I have a 2012 r6 with k&n race filter, smog block off plates, pc5,m4 go slip on, m4 cat delete pipe. I was wondering if it would be best to have a custom map built on the dyno for me or go with one from power commanders website. Any help would be much appreciated.

You should be able to find a good map from Power Commander. If that doesn't work, I would then go the dyno route.

Unless you have easy access to dyno services, I would go for the auto-tune setup for PC5 (I actually did this).

Do I need to take off the whole exhaust off to cut off the muffler box out or can I leave it on the bike and cut it ?
MotoSport Staff Expert Top 1 Contributor

Yes, you will need to remove your exhaust system before cutting as recommended by M4.

You will want to remove it for sure, there is grinding you will need to do on top of the pipe, that would be too hard to get to when mounted.

Does this mid pipe eliminate the o2 sensor? or is there a place for the old one to connect? I have a 2006 r6 with Jardine gp1 slip on.?

There is a hole on the top of this Eliminator Pipe that would allow the OEM O2 Sensor to hook up to the pipe. I would recommend taking a look at the installation instructions for this Kit before purchasing. Here is a link to the Installation Instructions for your bike: http://www.m4exhaust.com/products/art/systems/R6-08/YA-MBEKR606-Instructions.pdf

It has a pre-welded bung for the O2 sensor.

It comes with all the hardware to install it to the header pipes. When you buy the slip on you choose it will come with the clamps to attach it to the mid pipe.

If i install this on a 2012 r6 do i need to have the bike tuned or use a power commander?

When eliminating the Muffler box on your bike you would more than likely need to re-tune your bike using a power commander for better performance. With this in place of the Muffler Box the exhaust will flow more freely through the system than it did with the muffler box so your fuel/air mixture would have to be tuned to accommodate this change.

Unfortunately this will not fit on the KTM Duke 200. The Duke 200 is not a US model so we will not carry any parts that are specific to that bike.

I have a hot bodies slash cut megaphone slip-on exhaust on my 07 r6 will this kit fit smoothly or will I have to do some cutting?
MotoSport Staff

MotoSportExpert
Since this is designed to work with the stock muffler, any standard slip-on muffler should work just fine with it. The only issue is there may be slight manufacturing tolerance issues as the items are from 2 different companies. This shouldn't pose a big problem at all and only slight modifications may be required. Keep in mind on your 2007 R6 you will need to cut the muffler box off in the correct spot. This will then slip over the header and will not require any welding for installation.

Will I have to cut anything if I have a gytr slip on my 2007 r6?
I have a 2007 r6 with just a slip on. I know it says you have to cut off the stock muffler, but I have a gytr slip on. Will I have to cut off anything there

The slip on portion will not need to be modified. Since the GYTR slip on is built to the same spec as the stock slip on, it will be a direct fit.

WILL IT WORK WITH A Jardine GP-1 Slip-On Exhaust?
MotoSport Staff
2 years 2 months ago Location: Portland, OR, USA
MotoSportExpert
Since this is designed to fit with the stock muffler, *MOST* aftermarket slip-ons will fit without issue. Due to manufacturing tolerances between different companies, some slip-ons may not fit perfect and may need slight modification/adjustment to fit. I cannot guarantee exact fitment, but truthfully, it should work no problem for your 2006 R6.

Absolutely it will work. You won't have any issues installing your slip on to the new mid pipe.
