ScottyAdams Posted August 1, 2015 Share Posted August 1, 2015 They're stainless. About 3 bills. Going to have bike apart in winter. Pros? Cons? Mock up and then tighten stuff up? Sound better? Waste of money? Thanks in advance for your highly valuable opinions. Link to comment Share on other sites More sharing options...
Aimbot9000 Posted August 1, 2015 Share Posted August 1, 2015 It will be shiny and new. maybe an extra HP. Link to comment Share on other sites More sharing options...
seth89 Posted August 2, 2015 Share Posted August 2, 2015 A friend of mine bought the delkevic, "rubbish" hihi... Nah looked great and did fit very well. He did a remap with the headers and the other standard mods such as PC3 air-filter flapper, pair etc and got 105bhp on the wheel. Link to comment Share on other sites More sharing options...
ScottyAdams Posted August 3, 2015 Author Share Posted August 3, 2015 Two concerns; broken studs (will hit 'em with PB Blaster for several days ahead of time), and the headers coming to close to the cowls and melting them. But being a contortionist, I have no worries about reaching stuff, and both cowls and the clutch cover are coming off anyways. So, since I'm doing all that, I may as well trick it up a bit. Just want everyone's two cents. Thanks. Link to comment Share on other sites More sharing options...
Member Contributer Rush2112 Posted August 3, 2015 Member Contributer Share Posted August 3, 2015 They won't give you any more performance than the '99 stock headers you have, they have the same primary pipe ID (Internal Diameter)... you will only gain power if you are switching from the newer exhausts with a catalytic converter and smaller primaries to a cat-less and do the associated mods to take advantage of the engine breathing better... Since you already are missing the kitty you're not gaining anything performance wise. You'd gain more power from grinding the internal welds smooth on your existing headers primary pipe mounting flanges. They are stainless and shiny...

keef Posted August 3, 2015 Share Posted August 3, 2015 I bought a set a few years ago, and ceramic coated them. Catless, and lighter, and stainless. Not more performance as such, but much lighter, and with a much lighter scorpion can, less weight to push, feels faster. Link to comment Share on other sites More sharing options...
ScottyAdams Posted August 3, 2015 Author Share Posted August 3, 2015 Thanks for the input. Yeah, gotta have a project. As least they'll be shiny. I'll sand and polish the aluminum bits along the way too. Winter is 6 months in Cleveland. Plenty of time to screw stuff up. I've only ridden the VFR 400 miles this summer. It's one helluva bike. I reminds me very much of my Duc 900 SS (1997). Nice handling, but without the discomfort of all the weight on my wrists and not annoying grabby, dry clutch. I love this bike. I make pick up another to make it a long range bike with saddlebags and all that. It's a fine, fine machine. Wasn't even on my list. Just happened to be. Love it. And that V4 sound. With the gear whine. Man.... Link to comment Share on other sites More sharing options...

Rather than PB Blaster, you could hit them with a 50:50 blend of ATF and Acetone...that is the "best" way to loosen stubborn nuts/screws/bolts as measured in this study: http://machinistchest.blogspot.com/2014/01/lab-report-1-what-is-best-penetrating.html This really works...

highsider989 Posted September 10, 2015 Share Posted September 10, 2015 As the 98-99 headers are as rare as hens teeth, this is my best option for cat removal on my 2000. I'm itching to order a set. Unless someone has a set for sale? Link to comment Share on other sites More sharing options...
highsider989 Posted September 10, 2015 Share Posted September 10, 2015 And that being said I just picked up a set of 98-99 headers from ebay. Link to comment Share on other sites More sharing options...

I'm itching to order a set. Unless someone has a set for sale? Not really, I've seen several used sets on me-pay of late; however, I did go with new over 16 year old stockers. Or better yet, a used "new" set of SS for a great price: http://www.ebay.com/itm/Honda-vfr-delkevic-full-header-system-98-09-/321853703819?hash=item4aeff9c68b&vxp=mtr Link to comment Share on other sites More sharing options...

number9 Posted September 11, 2015 Share Posted September 11, 2015 Has anyone done dyno testing before and after to see how many bhp a set of headers frees up? Link to comment Share on other sites More sharing options...
CandyRedRC46 Posted September 11, 2015 Share Posted September 11, 2015 unless its a set of two brothers racing or erion headers, you are not picking up any measurable power. I have had factory 2007, then motad and then two brothers. the motad did not do anything. Link to comment Share on other sites More sharing options...

CandyRedRC46 Posted September 11, 2015 Share Posted September 11, 2015 No I've got auto tune so I don't need a dyno and no one has taken me up on the free comparo run. Sent from my A0001 using Tapatalk Link to comment Share on other sites More sharing options...
highsider989 Posted September 12, 2015 Share Posted September 12, 2015 i'll do it but need to wait till next month to get the PC3. it does cost you know. Link to comment Share on other sites More sharing options...

CandyRed arranged for a free dyno run of a stock (or close to) 6th gen at the US distributor for RapidBike in Orlando so we would have a same dyno comparison with CRRC46's bike for more accurate data. ... problem is we haven't had a 6th gen in Florida take him up on the offer!

I'll post up once they arrive. I need a month though as I need to order up the pc3 for a reall before and after dyno run. Link to comment Share on other sites More sharing options...
CandyRedRC46 Posted October 5, 2015 Share Posted October 5, 2015 The deal is, both of our bikes, on the same dyno the same day, back to back. There is no point in dynoing on a different dyno and different conditions. You meet me in Orlando, I will pay for your dyno run (not tuning).
