Your experience with the Akrapovic full system

[Beemah]

Has anyone put the Akrapovic titanium headers on a 2nd gen XR? I want to do the full system when I get mine. Big gains in performance?

Only done it with a gen1, but you will certainly need a means of altering the fueling because if the hole that is going to be left in the map around 4250 revs where the TUV live..

There’s a transformation to be had...well there is is with a gen1 😀

My experience on the Gen-1 with the narrow band O2 sensors....Gains will be minimal (if at all) unless remapped. It may well probably run worse in the lower-mid rpm range where the engine runs lean anyway...fitting headers makes it worse.

If using the standard muffler with headers on either Gen-1 or Gen-2...it "will" be loud.

dual wideband bike isnt going to behave the same way as an old school narrowband bike. Lots of posts of users in the XR facebook groups who have done it on a stock tune, and the AF has been fine.

Agreed....my thoughts were about the Gen-1 mainly as they're only narrow band O2 sensors. I'll edit my post to reflect that.

I’d be interested to see a dyno run showing such.

Yeah...mine was horrible in the low/mid range until I fitted the RBE.

I did a full Termignoni system on my Multistrada. Although it saved a lot of weight, it was very loud (much of the baffling happens in the catalytic converter). As mentioned above, you will need to re-map the ECU. I could never get it quite right so I experienced flat spots in the RPM range and the power gains were minimal. When I sold it and bought the XR, I decided to add a slip-on and leave the rest alone. It's fast enough IMO!

I am mainly interested in getting rid of the catalytic converter for the weight savings

I get it but for the average rider it isn’t a noticeable difference in handling and/or performance. Just be prepared for all that comes with eliminating it
