DR.D Stainless Slip-On Exhaust With Spark Arrestor DR.D Stainless Slip-On Exhaust With Spark Arrestor DR.D Stainless Slip-On Exhaust With Spark Arrestor 2009KawaskaiKFX450R (Castle Rock, CO) Dr. D slip on "After first day of riding fibers from the muffler packing were exposed in the front and ..." "After first day of riding fibers from the muffler packing were exposed in the front and rear of the muffler. The muffler decal was discolored undoubtedly from heat but the muffler itself remains original aluminum color. Emailed Dr. D Tech and Sales with no response from either department. Of course, the slip on provides good power increase over the stock Kawasaki KFX450 muffler. It's never a good sign of a reputable company when they don't respond to a customer's concerns after one day of use. The only Kawasaki upgrades are to the air filter, Procomm ECU set to richest setting, and slip on muffler. This was not a case of running too lean but poor muffler packing and end seals. I want to add the head pipe but will there be a defect in the quality of their pipes also? Now I have to repack a brand new $300 muffler and attempt to improve a defective seal all because the company's quality control is significantly lacking. Truely disappointing."
