417Shagnasty: Stage 1 jet kit folks... any change from stock back pressure and the stock intake vacuum pressure such as higher flow air filter will cause the nighthawk 750 to lose hp. and torque in the lower end of the rpm range. The stage 1 jet kit is even GREAT if you leave your exhaust and intake all factory stock. The low RPM and midrange grunt on my nighthawk and cold startup is much better now with the stage 1 jet kit installed!!
James Bregel: My baffles will not come out even with hammering the pilers as I pull. Nor did pb blaster help, I doubt you will respond but I hope you do.
Wade Hendrix: Did you do a before & after gas mileage results?I'd be interested to find out if drilling those holes increased or decreased it.It did sound better.
Larry Watkins: I'd like to hear it accelerate thru the gears, approaching thru first and second, and going away third-fifth. That would be a test of sound. Revving it without a load is not a true test. JMO
Carry Smith: after your done messing with your factory exhaust system,put ur bike on a dyno machine and ur gonna see,you didnt improve in anything it just got louder,ive had 2 buddies put there bikes on a dyno machine after removing the pipe baffles and both bikes,lost between 1/2 to 3HP on top end and the bikes fuel economy dropped from 45MPG to 38 MPG..
Mark Richards: Great Video.. Thanks..
Cosmos Wanderer: can i take my those out completely on my 250cc 2005 ? i need it to be louder i was almost hit by a car the other day.
All Things Super Moto: sounds so sick without baffles
Stephen Touzalin: thanx
ugirl2: my stock exhaust was custom cut shorties with baffles cut, my vid shows them it sounds pretty wicked just got a used vance and hines for real cheap so im selling them.
blytheluv: I need to try that carb modification.
shawnwhite08sw: I have a 650. it's not quite the same design exhaust, but is it the same concept to doing so?
Boards0nfire: I have a 450 nighthawk, how did it run without the baffles? I want to take mine out completely, think it'll run good?
jgr144: i have an 84 CB700s it basically has the same exhaust. i removed the baffles but i cannot remove the mufflers buried inside the pipe is there anyway i can do this without cutting them open
iamstillcrazy: Sounds at least like fired/burned pipe :/
InfernusEternum: I just hacked off the tube with a cutting wheel, same effect, less labor.
Carry Smith: ill belive all those exhaust modifications n after marker pipes give u more power,when i see a before n after dyno performence sheet.
motoryder: I just replaced the rivets on mine and i took it for a ride without the funnel and it sounds sweet!!
Nate Cole: it does sound better without the end pieces. i have a 91 nighthawk 750 and i am going to try this but try a couple different things with the baffle and see whats good or bad. ill put a video up of the different sounds.
