My R18 is still in Massachusetts waiting to be shipped back to me. So I can't say how it's going to ride in real life. Also, because I supplied a donor motorcycle (and shipped it back and forth), I did not have to pay for the tune itself. Now that it is done, Bren can sell you a handheld tuner...

Here are the before and after dyno results from Brenn Tuning (with the Hattech pipe). Big gains throughout, but massive at low RPM. Hit em up. I'm a big fan of both products.

Here are the two bungs. The larger ones in the front are for the o2 sensors. I also included pictures of the actual sensors that were in the smaller bungs. Temp maybe (I didn't google the part numbers)? It's running well without a tune, although I am shipping the bike to Bren the first week of...

Sorry -- the smallest video I can make is to large to upload.

Hattech Sidepipes video running.

Hattech Sidepipes installed.

I wrote to Hattech to tell them how happy I am with their Sidepipes. Today they responded with a link to BMW Motorrad Germany, which is positing pictures of customized R18s on its website. The headline picture is an R18 with Hattech Sidepipes...

By the way, the R18 does NOT have two 02 sensors per side. The front ones are 02. The second ones behind the cats are (I think) temp sensors. They are part of the exhaust valve control. It is a very different component (I know this because I pulled them off on my bike a couple of days ago to...

The Hattech Sidepipes are not a muffler swap. They are larger diameter, much shorter, no cats and no flapper valve (they do ship with plugs to spoof the ECU so that you don’t get any error codes). They are “off road — exhibition use only.” Although, like I said, not loud enough to draw any...

I received my Hattech Sidepipes (with the “works” finish) on Sunday, and we bolted them on right away. They took a long while to receive, but the wait was more than worth it. I’m traveling but will try to post pictures and a video with sound later this week. My observations so far are: 1. They...

I just bought a set of the Hatttech side pipes (the ones pictured above). Am waiting for delivery. I’ve been searching for information on whether installing these pipes requires a tune, and looking all over for a compatible tune or fuel controller. So far I have not learned anything. I emailed...
