Just be careful that she is not running too lean now Dave.  Overheating will do damage. Get a PC III and then a dyno tune.  Good peace of mind, and you will have one hell of a machine.  Twisted Evil

Yes do get the bike tuned. A blown motor will be expensive.

Perhaps this thing is going to explode but who knows.

I overtook three cars today on a longish straight, no oncoming traffic, separated by about 20m each - looked at the speedo - 179kmph (that's corrected by the way). affraid

And officer, I didn't think I even opened the throttle that much.  Embarassed

I'm going to get booked for sure. Sad

It didn't respond like this before I put those headers on.

Well I applied the poor mans PAIR block off today as I was a bit over the snap crackle and pop rice bubble effect, accentuated by the new headers.  I just blocked the air line at the join just below the upper frame member on the RHS.  Worked a treat.  Very Happy

What did you decide on in the end?  A bolt, RTV sealant or one of your old kidney stones?

Sorry, been away from the PC visiting family in Canberra.  The quality seems ok but the booklet that comes with it says to expect discolouring.  Other threads show people have been disappointed with this outcome.  I haven't done enough kms to notice any change in colour yet.

The Bandit headers are double walled thats why they keep most of the colour and only go a straw colour if not cleaned (I liked straw colour). Single walled SS will go blue at the hottest part. Think old Triumph exhausts.

Na all good Very Happy.

If they are anything like the stock headers you should be able to get rid of that discolouration by using a metal polish. Did my original headers the other day with California customs metal polish. I guess time will tell. I took advantage of the eBay Christmas 10% off sale and brought a set from that same mob for $417 delivered Very Happy. Are you going to look at putting a power commander on? Can't decide just yet, think it would probably be a good idea to fine tune the fuelling. Just trying to decide whether I get the 20-010 says bandit 2007-2009 or the 20-021 which they say if for the gsx1250 2010-2012 considering my bandits the 2012/13 not sure if going the 20-010 is correct.... Doing my head in lol

I'm not planning on installing a PC so I haven't looked into the serial numbering.

Ok, so I've drilled a 2mm hole in the blockage I put in the PAIRS tube. Let's see what happens. I'm expecting it might let enough air through to cause some decal popping but let's see. I can always fully restore the blockage in about 2 minutes. bom

AHey ewok, what exhaust are you running mate?

Installed the headers, tightened everything up, went to re- install my yoshi r77 and it doesn't matter what I try it will foul with the swing arm, unless it's on a stupid angle which then won't allow springs to re line up and the center stand stopper is of the a cock eye position. Rang delkevic, they said install original muffler , yep seems to fit, but said I didn't buy it for the original muffler.

Hmm, can't figure that out. My muffler is a Yoshi R77 carbon can. I'm surprised by your experience as I noticed that when I was reinstalling the O2 sensor into the Delkevic headers that it was a greater stretch on the wiring loom that goes to the sensor (enough to make me think it might break). That suggests to me that the headers had moved the connection point slightly further out from the frame, ie away from the swingarm.

I'll go and have another look at how close it is (but I'm not aware of how close it was with the standard headers so it mightn't tell me much). But it might help you.

IThanks for that ewok, after hours of trying to figure it out, I decided to use a bit of forceful love and bend the collector pipe at the end to give me enough clearance to be able to install my yoshi, I've got rid of the o2 sensor and installed my PC-v and new renthal bars. Bit deeper note. Sounds good can't wait to go for a ride and test her out tomorrow

Sorry mate - dinner guests arrived and 4 hours later I'm back at the PC.  Pics show about 1cm clearance and Yoshi pipe is very upright. Centre stand bracket is just touching the swing arm when the swingarm drops to maximum extension when the bike is on the centrestand.

That is strange. Delkevic should have the end of the collector finish at the same position and angle as the original headers. If their answer is to fit the original exhaust and that works then so should the R77, without modification.

It definitely does MM.  I had a Delkovic can on with the oem headers, and then changed to the Delkovic headers with can. All fitted fine.

Yea it had me stuffed, the original can lined up perfectly. The only other thing is maybe the link pipe had a bit more bend then intended? Either way I've "adjusted the angle and everything fits perfectly now. Def need my pairs kit to rock up that popping is so loud now haha

Let us know wot appens.

I replaced the roof and gutter sealant blockage with a wooden rod with a 4.8mm hole in the centre. Still no popping. I think I'll need aluminium if I'm to make the orifice any bigger as the wooden rod is too fragile. cheers

Are you aiming for a variable pop device or are you actually concerned about emissions?
