MotoCreations Boom Tubes exhaust for the S4RS

[c_rex]

The photos below show Boom Tubes for the S4RS but are made of pre-production materials, without exhaust tips just yet, and when they are completed will be available in natural stainless or ceramic black finishes.  They completely replace the stock header/udder and make provision for the O2 sensor.  Baffles are specially designed to mate with the Boom Tubes but I'm told they're still loud.  Just how loud?  It's going to be a long 6 weeks or so.  I think Mark has done an excellent job (again).  Check out the increased ground clearance.

Looks nice!  What kind of tips and can you post a vid w/ sound?

Dude that looks awesome  I can't wait to see the finished produt....

Maybe i can convince him to build a prototype for my bike?

Lookin good.

Be nice if someone figured this underbike exhaust thing out for us S*R owners.  I've seen options but they all are for DSS bikes.

Quat-D ExBox?

exbox is ugly and sounds tinny. i want these boomtubes on my S2R bad. REAL bad.

Does anyone know if this is the exact format they will be making, I know they are switching over to having them manufactured instead of hand made but if this exactly what they will be comming out with this year ()

Have you called Motocreations and talked about making you a set?  I believe NAKID has boomtubes on his S2R 1000.

CRex, what kind of finish are you planning for you boomtubes?  Ceramic?

[JDS 07 S4Rs]

Right on,,, . What is the OD of the pipe. Do we use any part of the OEM exhaust?

[jesse370]

christ, that thing probably sounds ANGRY.....

and everyone says my Rs with termi's is loud

+1.  no offense to others but I'm not a fan of the box on the exbox.  there are some sweet underbike exhausts out there for the monster (that include a crossover, baffles, etc); just not any I've seen other than these for the SSS monsters.

This one I can answer... yes- black!

Yup!

I'm still surprised by the response of BoomTubes by enthusiasts. Originally they were created for my DesmoDevil bike to retain cornering clearances and to visually keep the rear tire open as I'd have hated to hide it.  Thanks to enthusiasts, I've now handmade dozens over the past four years for friends or customer bikes.  Mostly all have been a variation of the original straightpipe iteration with baffles (aftermarket or of my own design). Unfortunately I haven't had the time with everything else happening at MotoCreations (DesmoDevil deliveries in particular) to produce more or jig for manufacturing production.  Until now that is.

With the move to outside of Tacoma, WA -- I've finally had the time to move a LARGE number of parts I've designed / prototyped and tested the past few years.  BoomTubes being the first most will see. (unless you see someone doing durability testing of other upcoming parts)  The past few months, I've played with the BoomTubes design, routing, sound and visual characteristics.  Then some simulation modeling outsourced to study exhaust flows.  They are no longer just "straight pipes" as what I've done in the past. (Wait until you see the final product)  All systems will be CNC mandrel bent in stainless and CNC welded. (I hate ugly welds!)  It took three months to find the facility that would actually produce what I want to the quality control standards I absolutely require.  Currently they have the S4R, S4Rs and S4 systems for the 4-valvers and are CMM'ing, building jigs and over the next few weeks will get me back the pre-production iteration for final testing/fitment.  Then production starts for customer delivery first against the database with people who've been inquiring for months. Then they will be released to the general public.

Iterations to follow within 60-90 days after the above ship are for the 695, 620, 800, 900, HyperMotard, S2R800 and S2R1000 -- and the 696.

All bikes are dyno'd with factory system (or if already using existing aftermarket system).  System built and optimized.  Then dyno'd again.  Fuel maps as required will be done and provided also via download for "standardized" scenarios.  Will do different mapping for the different baffle scenarios available.

The interesting part of this for myself is the move from "handmade" to "manufacturing production" and retaining "quality control".  I think I've spent more time the past few months doing engineering, stuck in meetings, conference calls, visiting facilities, checking references, building e-commerce capabilities, merchant services setup, business re-org or dyno testing than in fabrication itself. (It almost reminds me of my dot.com Internet days!) Fortunately I have four years of design and prototype experience to build exactly what I want now and how I want it to sound and function.

Thanks for the responses everyone!  Admittedly this is an exciting time upcoming here at MotoCreations -- and hopefully by this Fall we will be known for more than just our wild DesmoDevil line of motorcycles (and customer Monster projects) we have built over the past few years.
