Whats up guys.. i got a great deal on a Grayden Proline slip on exhaust for a 450R... i figured hey i have a set of torches and a welder so i can make it work on my 400EX :D.
I searched the forums and saw that it has been done before but i never found a wirte up on it.. so heres my little write up....
It didnt take a lot of work to make it fit.. matter of fact the only REAL modification i had to make was adding a bracket to the sub frame of my 400...the 450R apparantly has 2 support brackets holding the pipe up back there...
To make the Graydon slip on fit around my stock head pipe i had to expand the inner diameter of the slip on using a pipe expander i had from snap on... you could get creative and use an impact socket slightly larger than the I.D. along with a vice and lump hammer and make it work - although i dont recommend it but im sure it will work... i was able to slip the Graydon pipe on about an inch and a half with a thin bead of hondabond (as i do with all my exhaust joints just for security of no leaks) while using the factory 400ex support bracket on the sub frame...in the pics i still havent welded the second bracket as you can see..
Looking at the pic from the back you see where the baffle aims - towards the left.. that shows you how much i turned the pipe to keep it straight in line out the back without cutting anything up. I simply drilled out the rivits of the baffle aimed it where i wanted and re-rivited it. (not shown in pics) ill add new pics later..
Now the two brackets on the Graydon i had to bend about 45 degrees upward to to line up with the 400EX factory mount and my added mount.. next came a couple long bolts and some makeshift spacers made from black gas pipe :D..
any questions feel free to ask!! IDK HOW TO ADD MORE THAN ONE PIC! (DONT MIND MY RUSTY AXLE THE QUAD IS STILL UNDER CONSTRUCTION :) )
