Ok, found this pic of a nice Yamaha. Well, it looks nice to me. But I'm not too sure that the exhaust is street legal. It looks like MotoGP, but could you really use it on the street?

Can someone post the pic as an attachment? That site is blocked by my work firewall.

I think its pretty sweet. You can get away w/ exhaust like that around here.. no problem. Just saw a streetfighter at the ride on saturday, very similar exhaust. Pretty sweet looking.

I had to zoom in to see it! I couldn't even find it.
That exhaust is freakin' awesome! If didn't replace my Seca with an FZ6 (undertail exhaust) I'd be seriously thinking about a pimped out Seca!

It's not legal in Texas, and I have seen it written and hold up in court

from TX Transportation Code 547.604 :

Muffler Required

(a) "A motor vehicle shall be equipped with a muffler in good working condition that continually operates to prevent excessive or unusual noise."

(b) A person may not use a muffler cutout, bypass, or similar device on a motor vehicle

and yes a motorcycle is a "Motor vehicle" as defined by 541.201 (9) "Motorcycle means a motor vehicle, other than a tractor that is equipped with a with a rider's saddle and designed to have when propelled not more than 3 wheels on the ground"

I believe what you have to worry about in any state, as far as legality goes, is the noise (dB) level that is output by said exhaust. Those numbers vary significantly from state to state. If you're truely concerned about any exhaust you might want to put on you can always ask the shop for the dB levels of that exhaust and compare it to your state's limits at the American Motorcycle Association's website (which is down currently, as of this post) :nonod:

Texas doesn't have a decible limit set, and actually most states don't b/c of the debate of when the motorcycle produces a certain decible level, and a means of measurement, varying equipment, conditions, etc etc.

Here's the AMA link when the site comes back up, it's for Louisiana, but you can opt to change states.

Numbers i cant give you, but i know exhaust is essential to power. Your motor needs back pressure to help make torque and not having long enough pipes can ruin valves. (cold air comin in the wrong way) Or so ive been told, again... no numbers.
