Exhaust for track bike

[outthere]

My first post here. I've been reading threads and would like opinions. Which would you use from the list of currently manufactured systems? Thanks

Drummer SS (http://kdfab.com) or Dean Adams (http://deanadamsdesigns.com)
More info on the bike and maybe a pic or two would be nice.

Careful, as more and more tracks are implementing dB noise limits for vehicles to keep the neighbors happy. That bought their houses next to a race track. Duh.

If you are doing track days, there are no winners, so IMO stock is fine and easy on the ears.

If you are legitimately racing and theres money on the line, get the muffler that gives the most HP, the right tune for that pipe, and still watch the dB for the series tracks you'll be on.

102db max at the tracks we go to. The stock unit fell apart so we made our own with a car muffler. Bikes engines stock, air filter and all.

Okay so do not get the Drummer SS or a dean Adams.

What state are you in ? What trac level are you at ? what are the DB rules at the tracs you frequent?

 

[d_adams]

Stock is your only option if you can't exceed 102 db.

You can use whatever muffler you want it if your willing to get off the gas at the sound mic tower or towers. We don't have them at NJMP, they just ask us not to light up any motors cars/bikes before 8a.m. If you're doing ccs or wera racing then i understand you can't afford to get off the gas but if you're only doing track days then who cares, just back off the throttle!

I'm in CA. Mostly ride @ Thunderhill. Track days only. B rider. Hard to imagine a big twin more offensive that a 4 cyl. Limit is 103.

Have you HEARD Deans pipe?? Or APH? Love the sound but dang...:black_eyed:

 

[outthere]

I have not. Suppose there loud? And after a bit more research the only company offering full systems is APH? Edit: Dean adams also

 

[Silverrider]

T hill , they are very lax there , get a loud pipe & a matching tune ,back off by the tower , Have fun in the B group.

 

[outthere]

Loud doesn't necessarily mean usable. Any recommendations?

I believe theres an "exhaust shoot-out" you can look up. Keda Designs (Deans pipe) had the highest HP and sounds fantastic. Built solid.

Jardines are known to blow up.

Other than that you-tube has tons of crappy iPhone videos for subjective sound comparos.

 

[d_adams]

Need more info. Bike, year, displacement, etc. XB12? 1125? 1190?

 

[outthere]

2009 XB12. Had a Jardine fall apart already

(1) Drummer SS has a dB killer option for purchase and Kevin is really easy to work with.
(2) Dean Adams RTXB-1 has a DIY dB killer option (108dB @ 5000 rpm at a distance of 6' is what I tested at). I made the DIY video after trying to drop my dB for a possible trip to Laguna Seca. It also makes my early morning departure for work much quieter in general.

What part of CA are you in? I am in the Orange County area.

North of SF 100 miles. Cloverdale to be exact.
