With the Two Brothers Racing M-2 & M-5 Slip-Ons, you'll pick up an additional 4.5hp for the 2006-08 BMW K1200GT and lose 14 lbs of excess sprung weight. Win/Win!

M-2 Series Information: Their M-2 small oval exhaust system features the TwoBros exclusive Teflon coated, blunted, cast magnesium outlet that not only looks too cool but also allows for various silencer inserts. These are the smallest canisters on the market measuring a full 1" shorter than the competition.

M-5 Series Canister Information: The M5 large oval canister, which features a 2.25" Stainless Steel Spiral Power Core, is the largest oval canister TB makes. The core is what controls the power and sound, not the shape or material of the canister. The M-5 incorporates exclusive technology and premium construction material.

Black Series: The "Black Series" is Two Bros prestige line of high performance exhausts! Black Series systems are fitted with black bands, black inlet/outlets, and a black endcap.

Logo or No Logo? Many prefer their canisters to be a little more clandestine.. Not a problem. The new M-2 and M-5 canisters shown here have a sticker.. not the old style metal logo. The sticker can be peeled off BEFORE starting the bike. No problem.

Pirates' Lair includes the TBR P1 PowerTip™ sound suppressor (usually a $30 option) with all TwoBros exhaust systems with M2 or M5 outlets. Use it.. or not! The P1 is a straight-through sound diffuser which quiets the pipe by 2 to 3 dB while actually adding measurable HP gains from the middle to the top of the powerband. Easy to install - simply unbolt your existing M series end cap, drop in the P1 and reassemble. We even give our customers a choice of 2 colors at no extra charge. Black or Gold. Just specify when ordering.

Remember... Pirates' Lair pricing includes the aforementioned TBR P1 PowerTip and USPS Priority shipping to your door (if inside the US). Others do not.
