F800GS Exhaust Pipes

I got the two-brothers for my 800. It's very nice, light, and loud. Had to get their db killer because it was too loud. About half the width and weight of stock muffler. Also a fraction of price from Remus or akropovic.

I have just finished custom headers + system for my BMW650 (twin).
Have dyno sheets from tuning afterwards. 18% more torque, 13% more power. Polished 304 stainless. Sound whilst cruising nice, wide open throttle has really nice bark. Better fuel economy. Have pictures will post when learn how (new to forums...) Saves 4.5 kgs in weight.

Might be some useful info here....

Seriously? 13% more.... you might want to post a dyno chart to go with that claim.

... I didn't dare ask....

Prolly not peak numbers but rather max delta--likely at or near redline.

The reason why we upgraded the exhaust + tune..is because of an engine vibration problem (in hot weather i.e. Qld) Local BMW seemed unable to rectify. The Motorcycle after exhaust + tuning is a complete different bike to ride (more torque, enjoyable, less fuel/using less throttle opening). All good. Before these mods. it would struggle at 175 kmh now it will easily go up to 200 kmh. Used our motor racing knowledge for the design of the headers. Endeavouring to upload photos.. (learning).

Any chance you could upload pics to flickr, Picasa or similar and just include the link?

F700, not an 800, but you get it.

Two Brothers M2 VALE carbon fiber slip on. 3lbs vs 11lbs OEM





I dig it. Sorry for the terrible lighting. I'll take better pics in daylight.

I havent seen anything that makes more than 5hp yet personally....

How loud? I've heard the 2B are a little obnoxious.

Hard to define obnoxious. Guess it's on personal preference.

It's not squid/sport bike or Harley loud. It has a bark at start up. But mellows out at speed/under load.


Here's a random video I found googling. Seems on par with the LV.

complete system manifolds and exhaust

I like that two brothers exhaust, it looks and sounds sweet. My only problem with it is that the website says it needs to be repacked every 3000 miles?

wtf?

Unless they use crappy glass insulation, Id say easy 3-5 years, and then perhaps then some....

I just emailed two brothers asking if 3000 miles according to their site is correct?

Any good specials out there on exhausts? Scorpion discontinued distribution of it's carbon fiber exhaust to North America.

I'm looking into the leo vince now...

Call renazco Racing, as for James, tell him Erling send you his way, and see what he can do.....

It was a bit too loud for my liking...

I bought one of their inserts that reduces the decibels a few and it's just about perfect.

Hi :)

I just bought a second hand Leovince for the 700GS.

I've a question for the removal of the stock exhaust.

I must remove the two springs and the exhaust "holding" screw and that's it, I can pull the exhaust out?

For the new one, any seal or something like that?
