I soo hate to see pipes with telescoping headpipes,header pipe,next is a larger pipe slid over the head pipe and so on,,PG,Leo vince,Technigas,etc. like this method cause its cheap,,works fine when the exhaust gas is going out,but what about the reflected returning mixture charge before the exhaust port closes?Kinda like a down hill skier on a stair well!Tapered head pipes are where its at,gotta have that smooth flow(in both directions) to have a decent pipe..A quiet pipe would be ideal for this ride,the Penton/KTM dirt bikes had the most simple set up kinda like this;  Ive used this baffle setup on many pipes and love it,doesnt hurt the power at all,but makes it nice and quiet.. You beat me to it! I was going to be asking about that exact silencer design, separate silencers are so much work. Thanks for the illustration!! |

I also decided to cut up my oem rack to see if I can make it alittle sleeker. It's kind of needed to put the bike on the center stand. It's not done yet just test fitting everything. If it looks like garbage I'll just trash the idea. First here is the original  Oem chopped up  Bent into shape  Mock up   Opinions?? |

Paint that sucker and bolt it on! Still kept lifting functionality, but got rid of the excess wire rack look.

It sure looks better without it, but I agree about functionality. You need something to grab to get it up in the center stand.

I'd ditch it altogether, and find something to cap the studs off with. It takes away from how clean your new tail light looks.

It has that retro feel to it. Kinda, sorta, a little bit reminds me of Vespa's and Lambretta's. Kinda. :/

For some reason I was thinking this morning that his cut out pieces were connected and that he rolled them up somehow. Looking at the thread again I see that he just has them close to each other. Blind persons optical illusion. :/

That's just how they made the template. That straight pipe won't fit s**t. You need to make many templates to work the angles. I made a mina horizontal which was easy compaired to this vertical. The head pipe didn't even make it to the bottom of the motor. My plan is to keep it tight to the fan shroud then close to the body panels in the rear. Silmilar to this but with an intergrated muffler.  |
