rzr exhaust

[rocet23]

well ive noticed the restrictor and im going to cut it out.to do this the chamber has to be cut on the second last weld.inside there is a plate with two round sleeves going through the plate.these sleeves are about 10mm diameter.the exhaust gases go through these sleeves,so its very restricted.i had a chamber with this mod done on one side only and it sounds a lot better.this chamber also had a modded baffle.with this set up it sounds good but you now what cops are like so i ran the modded chamber with a full length baffle and its quiter.the restricter is welded in with 4 button welds witch you can see from the outside off the chamber. the pipes i have are the type with a alloy end can,standard for this rzr 250 1988 model. i also noticed ther is a restrictor in the air box under the top cover that just slides out.not sure if there is a gain with this mod,but i bet there is.
