Now that we’ve stressed on the proper way to go about installing your Slip-On Exhaust System Sound Level: Quiet By HMF Racing, lets talk about the 10-15% more horse power throughout the power curve that you’re going to be getting. You will also receive a huge amount of torque. The shell is stainless steel and is much lighter than the stock exhaust. This is durability at its best! The Polaris Ranger 800 XP EFI comes as a Slip-On System in the Titan exhaust. The Titan-QS can be louder than stock by 1 to 2 decibels while the Titan-XL goes up by another 4 to 6 decibels. You really do need to remember to Fuel Tune as the damage done can wreak havoc on both your exhaust system AND engine and you will not only void the warrant on your exhaust but run the risk of voiding the warranty on your machine too! Take care of the machine you love!
