Open exhaust requires raising the exhaust port very high and a very high exhaust port is only good for competition drag racing. If your exhaust ports are not setup for open exhausts, the exhaust pulse will not leave the cylinder in the most efficient manner. Some motors will run better when ran without silencers and\or silencer packing, but these motors were built for this. If you wanted a loud quad, id recommend a 4 stroke, they are plain annoying they are so loud. When folks see someone on a loud 2 stroke its a sure sign he's a newbie to how motors' work. If removing the silencer packing would give you an inch of performance then all the pro's would do it.
Have you ever seen any professional MXer's, bikes or quads, race without any silencer ? Nope. Think indy car sound instead of Harley Davidson sound A ring-dinging 2 stroke motor sounds best when its pushin out a properly packed silencer.
III or, any other type of fuel processor. In fact, the guy from, says if all you do is add a stage 1 a/c and a set of pipes, the Xides will handle the lean condition with out remaping or a P.C. The exhaust pipe was designed to run best with a packed silencer.īesides, loud is not cool. You wont need to remap for slip ons, or removing the baffles from the stock pipes. Mabe I'm just getting older so loud noises grate on me more.Dont do it. Have I done it wrong or is it just that this sort of pipe is never going to be any quieter?
I was slightly dissappoint to find that it didn't make a massive different to the perceeved loudness. I bought some loose fill K-glass type packing and used both that and the old stull to completely re-fill. Then Installed these Baffles and the sound was much better, about 79-80 Db standing about 50 feet. Wow the sound was very loud and about 90-91 Db standing about 50 feet away. I needed about 6" worth of loosing packing wool to top the silencer up with. Then I took out the standard baffles that came with the Vance & Hines pipes. Once I added all the extra bits back in my pipe it then looked like this. So I've flipped the whole chunck of packing around thus putting the good end towards the back, and then pushed it down as far as it'd go. No doubt this cavity would then allow it to slowly remove the rest of the packing. So my tail pipe had made itself a nice little open chamber to resonate the exhaust gases in. Remove the baffles from a Cobra system and youve just voided the lifetime warranty that. You may have to twist a little or tap it with a rubber mallet to break it free. Remove those bolts, then grab the end of the baffle and pull it straight back and out. You will have to loosen the exhaust mounting bolts and pull the pipes outward to access the inner bolts. Packing laid out along side pipe to show how much wadding had been eaten away. Do your pipes have removable baffles I want it to be loud. Each has 2 4mm allen bolts 90 apart from each other. Then I noticed that the packing fell short a few inch's at the back of the can (or front depending on which way you think of it - the end nearest the engine). I was in slight disbelief though as my pipe seemed nosier for sure so I decided to drill out the 8 rivets that hold the other end on. The packing still looked pretty much the same. Well 2 years on and I'm sure my exhaust has been getting louder so I decided to take a look again. 2 years ago I drilled off the rivets to remove the end cap to see what my exhaust packing looked like, it was still almost new looking.
