got nothin' better to do... and it was interesting reading the evolution of the header build. Btw I wasn't the 1st member to ask that question and he didn't get as much flack as I did so I think it only fair for those who commented to my post go back through the thousand pages of posts to find the 1st post and retroactively give him some of what I got.

They're on page 26, along with the info on how to purchase the files, which is why I wanted to locate the post... and it only took me 90 minutes. Sent from my SM-G975U using Tapatalk

I make enough popping and gurgling sounds myself, I don’t like my exhaust to mimic me 👴🏼

I think there is a short metal backing piece under the chain guard, nearly impossible to see or reach into which the screw goes. I'll have to go out and have another look but I remember having a heck of a time getting that attached in the past. I'll update later.

No flack mate. Now going back thru the thread for yourself you found 'this' story and its history and feel good about yourself for doing so, yes? And I commend you for doing so

Google "New 5th/6th/8th gen performance header now in production in USA dyno" https://www.google.com/search?sxsrf=ALeKk02LcBd32MewRnlkFLizSGA2J6lWcA:1592001539406&source=univ&tbm=isch&q=New+5th/6th/8th+gen+performance+header+now+in+production+in+USA+dyno&sa=X&ved=2ahUKEwiNtfPxq_3pAhXhN30KHaodCooQ7Al6BAgKEBk&biw=1920&bih=937#imgrc=s96ctphRTaH7mM

Replaced this... with this...

Confirming what Duc2V4 said - the maps will be here and available on an ongoing basis.

Jozef - our favorite dyno technician in the world and head of tuning at Attack Performance - has provided the maps he built on the dyno for: 5 gen VFR800 tuned with Power Commander 3 6 gen VFR800 tuned with Power Commander 5 8 gen VFR800 tuned with Power Commander 5 These maps will work well on any 5th, 6th, or 8th gen VFR800 with the new performance headers, a good quality hi-flow air filter [We prefer the K&N HA-8098 filter] and a good quality slipon muffler. If you have purchased these headers and would like to utilize one of these maps to optimize your VFR's performance without trucking it out to a dyno shop, we can email the map for your gen VFR to you for a donation of $50. Please send 'sending to a friend' to the paypal account of vfrheaders@gmail.com, and in the note section of the paypal transfer, specify the email address you'd like us to send the map to. Below are the dyno charts for the three maps. These maps were posted early on in this thread, but are included here to save people the trouble of locating them in the way-back portion of this thread. Each chart has three traces: [1] a baseline run with OEM headers [2] a run done with the new headers installed and a zero map, meaning no tuning and no changes to OEM ECU fueling were entered into the Power Commander map [3] a final run after a complete tune was performed There are two versions of each chart: [1] a chart with a reference line at peak horsepower/torque [2] the same chart with a reference line at midrange 7000rpm to demonstrate the midrange gains achieved with tuning the new headers [8 gen kicked butt at 7000rpm with 16% gains in both horsepower and torque] 5 gen Power Commander 3 map [peak]: 5 gen Power Commander 3 map [midrange]: 6 gen Power Commander 5 map [peak]: 6 gen Power Commander 5 map [midrange]: 8 gen Power Commander 5 map [peak]: 8 gen Power Commander 5 map [midrange]:

What can i say i was just pointing out the obvious. I am vey happy with the header nevertheless i have purchased several headers for my other motorcycles kerker, akra and hindle and never had clearance issues. I applaud the commitment to get the header into production and to rectify the issue in other runs. I just don't understand the snide comments. I don't recall anyone jumping all over the guy who was aggravated over the exhaust gasket size.
