2009 EFI Thruxton d&d 2 into 1 exhaust

Hey you guys I just installed my d&d 2 into 1 on my 2009 EFI thruxton. I have some concerns that I want to share and see if anyone has any answers. The exhaust sounds great, really mean, maybe a little too loud but I as soon as I hit 3k rpm and let go of the throttle I get a really loud back fire. I'm assuming I have to get my bike's fuel map remapped but is it normal that it pops at 3k rpm? I don't have any other performance modifications.

Also I'm getting a little condensation leak between the 2 into 1 mid pipe and the silencer pipe. The clamp is on tight so not sure where the condensation is coming from.

Can anyone help? Thanks.

Most likely needs to be remapped.

The exhaust looks great! Just some info or maybe something to check. I had D&D's TT style pipes on my EFI Thruxton and had issues with leaks at the flanges. The flanges were actually running into the fins on the head so they wouldn't seat right.
I ground some clearance on the flanges which helped but I ended up using a exhaust gasket from a GSXR1000 which is a perfect fit and about the thickness of two or three of the stock Triumph gaskets
For what it's worth, my bike ran like crap as soon as the AI was moved.
I'm runnin a Power Commander V with a custom tune and the bike runs great.
I would suggest getting some kind of fuel mapping done.
Good luck

I run them on my bike its a carbed bike but they still should not pop like yours is you need a remap .I use high temp rtv to seal the joints.When you get them right on let off they will just rumble alittle kinda like a machine gun buy not a loud bang or pop.They are the hp king so far on these bikes.

Why do I feel young on my bike

yeah, your new pipes do look good but you will need a remap with an EFI !

My apologies. I replied to your pm but I guess it didn't go through. I checked on the freight again and found it would cost 5 to 600 dollars to ship to Australia. The shipping company won't let me just bubble wrap it so I boxed it in the d&d box that I received and it measures out to 28 length 22 width and 13.5 height. I have no idea where the first cost came from.

I wasn't dodging you I thought I replied but I guess it didn't go through. Anyways, I figured you wouldn't want to pay a ridiculous amount for me to ship to you.

ok, your forgiven good luck with your re mapping !

yeah not sure where you got the first quote from either ? oh well things are obviously real bad in the states with those high prices. was that just USPS too ? reckon I could get them via DHL door to door cheaper than that ?
anyone out there coming to Australia now that Oprah has done her thing ?

Anyone know if a Air box removal kit is necessary after getting a full exhaust system put on?
