Screamin' Eagle Pro Torque Mufflers WHY? Sound and performance.  I read a recent survey that said that some 85% of Harley-Davidson motorcycle owners had modified or replaced their stock exhaust systems.  There's no denying that the V-twin exhaust note is a part of the Harley mystique, and replacing the restrictive exhaust is generally good for a few horsepower; while I don't care for loud exhaust on my bikes I'm always looking for a performance gain, so I set out looking for the right combination of sound and power.  The stock exhaust on the Softail utilizes a crossover tube that gives the dual-exhaust look favored by many owners while offering some of the advantages of a 2-into-1 exhaust system--generally better exhaust scavenging and improved low and mid-range torque.  For this reason I decided to look for slip-fit replacement mufflers that worked with the stock crossover tube.  I tried a pair of the highly-regarded Khrome Werks mufflers but found them to be just too loud for my taste; ditto with a set of H-D Screamin' Eagle II slip-ons.  I was about to abandon hope of finding any replacement performance mufflers when I read about the Screamin' Eagle Pro Torque mufflers (part #80388-01); they're designed to deliver low-end torque and they're quieter than the Screamin' Eagle II series.  After comparing prices I went back to my favorite online dealer, Zanotti's.  They had 'em listed for under $200 (list price $249) so I placed the order. SERVICE.  Excellent.  After ordering I received a confirmation email from Zanotti's parts department; the next day I received a notification that they had the item in stock and would ship immediately.  I received an email the next day notifying me that it had shipped.  The box arrived at my door via UPS ground four days later.  I've done a great deal of shopping online, and I believe that Zanotti's service is about as good as I've seen; other vendors would do well to take note.  The mufflers arrived well-packed and undamaged, with extra clamps and gaskets; installation instructions were not included. INSTALLATION. Even without instructions the average home mechanic should be able to handle this installation.  The most difficult part of the task was the removal of the stock mufflers from the headpipes; I saved myself some major gruntwork by squirting some penetrating oil on the junction where the muffler neck meets the header pipe.  After allowing it to sit for a few minutes I used a strap-type oil filter wrench to turn the muffler bodies and break loose the crud and corrosion; after that maneuver the mufflers slipped right off.  I slipped the new ones in place and tightened the clamps and mounting bolts.  Before starting the engine to check for leaks I was careful to use some Windex and a towel to clean grease and fingerprints from the chrome; once the muffler is hot they'll bake right on.  I installed the stock heat shield on the front muffler to provide protection from my boot, but I left the rear muffler as-is so that the "Screamin Eagle" script would be visible.  The entire process took me about 20 minutes.  Since I had installed a Screamin' Eagle Stage I Air Cleaner kit I took the bike to the dealership to have the ECU re-programmed before test-riding it.  You can read about that process here. RESULTS.  Tempting, but not a keeper.  Of all the mufflers I've heard these have the most beautiful sound; it's mellow and very low, not harsh and raspy like some others.  They are definitely louder than the stock exhaust, however, and are just a bit too rowdy for a middle-aged minister.  I like the appearance of these pipes because I've always liked the looks of the stock tapered mufflers; the chrome finish is flawless.  Since I made this change as part of the Stage 1 Upgrade it's hard to tell how much performance gain was due to the mufflers themselves, but the upgrade did make a significant difference in power. Worth the money?   Probably for most owners, but not for me.
