With the Two Brothers Racing Slip-On's, you'll pick up an additional 3.5hp for the BMW K1200R and an extra 5.4hp for the BMW K1200S and lose lots of excess weight..

M-2 Series Information: (Pics at left and below) Their M-2 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.

Pirates' Lair includes the TBR P1 PowerTip™ sound suppressor (a $30 option) with all TwoBros exhaust systems with M2 outlets. Use it.. or not! The P1 is a straight-through sound diffuser which quiets the pipe by 2 to 3 dB while not causing any measurable HP loss. Easy to install - simply unbolt your existing M series endcap, drop in the P1 and reassemble.

M-5 Series Canister Information: The M5 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.

Logo Preference Info: Many purists prefer their canister's without the Two Bros yellow logo riveted on and due to the volumes we sell, Two Bros gives us the option of ordering with or without. They charge us $25 extra for this service (I'll assume to discourage us and everyone else from doing it) and that's what we charge our customers. If you order using the buttons below.. your canister will will arrive WITH the logo. If you'd like to order WITHOUT the cheesy logo.. Just give Amber a call.. Your choice. If you call an order in at 828.628.7093 EST and do NOT specify, your system will arrive with the logo.
