MotoCreations Boom Tubes exhaust for the S4RS

[angler]

I just PM'ed you Mark.  I'm interested.  Has any one posted decibel levels for factory and various performance exhausts?  I would be really interested to see those.....I have cored stock cans minus the udder and wonder how much louder these things will be.....

[Buckethead]

Shit. Now you've got me thinking that I should just take the mufflers off my Sport 1000 and not worry about getting an aftermarket exhaust.

Although the boom tubes are not something I want for my Ducati,  I really want to commend you Mark on all that you have done here.  I can't wait to see more videos.

Thanks for the words of recognition.  It is appreciated because it has taken a lot of work to make happen -vs- continual one-off products and bikes over the years.  As for videos?  I'm waiting for the giant customer BoomTube video production -- early 2009 hopefully with four years of BoomTube stuff as customers send them in (finally!) and new customers who are getting systems here shortly.  Definitely will be on YouTube along with a few other MotoCreations videos underway for a retrosport inspired bike for myself.

Are the baffles going to be able to be taken in and out?

Yes.

As I see there is a bit of an update on the MotoCreations website, I just had a question about the Boomtubes. On the S4RS you see easily how much added ground clearance you gain with the Boom tubes. However it looks like the S2R1000 model has no real clearance difference compared to any other mainstream aftermarket exhaust, Is that the case? 

Also not to echo everyone else on the thread but when are we going to get some more sound clips. I am solely waiting on those before I pull the trigger.

You're not allowed to put aany more bling on your bike. It might explode.

They're both about the same distance from the ground, the S4RS exhaust just goes on the other side of the deep sump and makes it look higher....

Site says "base model" exhaust baffles..

What does this mean??? - Do you have a dB value?? I'm looking for something within the same range as arrows - 102-105db.. In my case, less is better than more. I dont want it any louder than the 105dB range.

Any sound clips yet???

You said you've done dyno's; I was hoping you have a sound sample somewhere..

2) Chris/Nakid's system is the older style BoomTubes I did.  Yes -- there have been different flavors as I went along.  37+ handmade systems have allowed myself to do some tuning / experimentation along the way.  Newer systems have a more gentle "overrun / off throttle" response.

3) Nakid's system is now "wide open".  No restrictions or baffles in them at all.  Even in this configuration, they are tolerable at low/mid rpm.  WOT -- it sounds like you are riding the chariot into the Roman Coliseum with the crowd getting excited.

Great work, what a fantastic sound! Not to thread jack or anything, but what causes the enormous amount of sound during engine braking? A friend of mine and I both have a '94 M900, I've got low-mount Termi's (oval CF, no baffles, runnin' a little lean still), and he's got high-mount DP (oval SS, Remus I think, no baffles and perhaps a bit rich). When he closes the throttle, there is this massive wave of sound (nothing like the boomtubes, but hey, what comes close?), while my bike sounds (too?) civilised. Is it the construction of the pipes? Or the fueling setup? Any thoughts?

Cheers!

thats either an open airbox or pods.

I have pods on mine and they sound beastly..

[Bizzarrini]

Nah, he's got the full lid, with both tips (removed one now, running a bit better, only the sound under acceleration got louder), and the OEM filter, while i'm runnin' the K&N filter with full lid (tried removing one of the tips, but ran very crappy afterwards)...

I don't have an open airbox or pods. I do have 2 1.5"X1.5" holes cut in the back of the lid...
