really not gonna make a difference..inf fact it kcan hurt performance all the way around...engines need a certain amount of backpressure to make a proper power band and torque curve...i wouldnt do that...

#1 reason it sounds horrible and is kinda gooffy

I agree I would not do it but it doesnt sound much different then the shorty tip's he had on it at 1st. and there seems to be a lot of guys running the short slash cut tip's with out the baffles so then they all lost back pressure and are loseing hp?

listen man I remember last year when I took off my mufflers to install a yoshi exhaust and loved the sound without the mufflers and ended up throwing the yoshi exhaust in my garage. So i asked around and came to the decision to run it without mufflers. so i did for about a month then ordered the hotbodies shorty exhaust which i ran for the rest of the year and some this year with absolutly no problems. I never lost a single horsepower (going by feeling on this with no actual numbers to prove it), and the sound was absolutly amazing. I was honestly happy with it the way it ran and sounded. Then i just upgraded to a brocks exhaust and i'm really happy with it. But to answer your question about hurting your bike, you couldn't hurt it if you tried. Bikes now a days (especially such a high performance machine as the gen 2 busa) are so well equiped from the factory that they are basically idiot proof. your ecu will compensate for any changes that might occur to your bike. So i say take the mufflers off and enjoy it. but i would atleast order the hotbodies tips cause they look sick. :thumbsup:

Interesting look on things. I think if you are going to lop the exhaust off, a custom map may be in order to compensate for the changes. The ECU can only do so much. Then again I assume if one wants to run no exhaust, they probably would not spring for a tune either. :beerchug:

No tune is necessary unless u want that extra 2 horsepower and a better curve. What the guy is asking is that if it would hurt his bike and I say hell no cause I've done it for a long time. Now my honest opinion for a great exhaust is the brocks and a pc. Now I agree its not the most efficient but it will work just fine
