    350x/450r exhaust conversion

    350x/450r exhaust conversion
    well i decided that in stead of trying to gimmy rig my super trapp that i would custom make the 450r mufler to work! All i had to do was cut up the old super trapp which was rusted out and weld a little bit to make a mid pipe to form the right bend to go inside the frame! Well i am very satisfied with the end results. It sounds like a stock 450r. I havent noticed any loss but i do know now that i have a little more back pressure it seems to rev alot quicker! Its very quite but i love the grunt when i wake up the motor! All in all i would recomend this conversion to anyone that needs a quiter pipe with just as much power gains as some of the loud ones do! I also forgot to mention above that i did put on the hrc tip to improve perfomance and thats what gives it the best low end grunt!

    That HRC tip makes it sound MEAN, doesn't it?
