MotoCreations Boom Tubes exhaust for the S4RS

[He Man]

if i had to guess, theres no place for the gas to expand, so the sound just comes out raw.

for real exahust systems. the gas has a chance to expand (thus queit down).

Well I just ordered a set with black ceramic coating, the quietest baffles and pencil tips.  It will likely take me until the end of January to get them installed, but count on me to record sound levels with my current cored and udderless stock system, no baffles, and with the quietest baffles Mark uses.  Anybody in the DC metro have a decibel meter?  If I had one, I'd measure dB as well.

I've got to say that Mark is a pleasure to do business with as he definitely puts the customer first!

hey. i have the termi system and it has the fit and finish that only a racer could love. i get 126 rwhp (dyn0-tuned) and it sounds great: not too loud, just a great growl. but the pipes, especially, look like sh1t, while the carbon is slowly fading, i think.

plus, hell, the low slung look of these boom-tubes is awesome. i want!

but i would like more data regarding db. there should be more on youtube. come on guys

Bumping this up to see if anyone has measured db, posted sound files, youtube, anything.

Thanks!

Just in time, I guess I'll wait on new pipes until your 696 stuff comes out...

Just bought a set for my S4RS, I plan on doing a before and after pic + youtube of each.  Don't have a decibel meter or anything handy though.

If I take the video with the same camera both times, I figure it'll give a pretty good representation of the sound difference.  I run just the open udder at the moment.  Installing Boomtubes with medium baffling hopefully sometime this week.

Open airbox, open clutch, FatDuc on my setup.

Any rev requests?  Idle, rev to 8k, hold at 4k or something like that was what I was thinking.  With the udder, then the 'tubes.

No guarantee on the sound clips, I'm just trying to be nice    I'll try my best to do it scientifcally.

My neighbors may end up shooting at me before I'm done.

Go find yourself an industrial park on a a Sunday to do your passes...
