I finally decided to upgrade the exhaust on my k5 DL650. After much research, I decided on the stainless model from Scorpion. The reviews said it was not too loud, never needs repacking, and has a lifetime warranty. A quick check with my preferred farkle vendor, amotostuff.com, and I located what I needed for a very reasonable $287, free shipping and no sales tax :lol: . Like always, Adv. Moto Stuff was on the ball, I ordered Wed. afternoon, and the box via UPS was on my porch Friday afternoon (Reno to So. CA). The product looked to be of very high quality with a nice fit/finish and polishing.
The install is quite simple, and the instructions are limited to a diagram showing the parts. I like that "RACE ONLY" warning:
Ignore the two parts pictured below (#10 and #11), they will not be needed unless you find a reason to ever reattach the stock muffler. This is where the diagram could confuse some people.
First up, I quickly removed my Motech racks/panniers and the right side passenger peg mount. Then you need to remove the lower black plastic heat shield (3 allen bolts). Now the important part, measure 50 mm up from the center of the lower shield bracket. As Norm says "measure twice cut once", I used a set of calipers and a silver sharpie.
Then a couple of zip ties to mark the cut line and hopefully allow a straight cut:
You won't be able to get a full size hacksaw in there to cut the pipe, so I choose one of these:
It took about 15 minutes and a couple of kinked blades, but the cut came out just fine. A sawzall or air cutter would have been easier, just make sure to cover the brake line on the swingarm so you don't do any unintended cutting. I thought about using my dremel, but it would be a litle awkward in the tight confines.
Next, unbolt the two bolts that hold the stock muffler on and remove it. Now I figured I'd better fire up the strom just to "make sure" that no metal shavings remain in the open pipe :twisted: . Man did that 650 sound sweet with no muffler! Very loud, kind of like a top fuel v-8. I fought off the urge to drive around the neighborhood reaking havoc, and proceeded to the next step. From here, it's about a 10 minute job to fit the mid pipe, two clamps, the muffler, and the mounting strap. Everything fit perfectly! If you did a good job measuring that 50 mm, the stock heat shield bolts right back on using all three bolts, one of which comes on the new mid pipe.
The can looks really nice in stainless, too bad it will be hidden behind my Pelicans.
Still plenty of clearance between the new can and the SW motech racks:
Here's a before/after shot comparing the Scorpion with the stock can. The stock is at least twice the weight of the stainless Scorpion:
Now for the moment of truth, fire up the engine and listen to the very nice throaty growl of the v-twin. It sounds great, not too loud, but just the right amount of throaty growl to remind you that this is a motorcycle and not a sewing machine. I'm on Mr. Mom duty this weekend, so I have not had a chance to test it out yet, but my buddy did go for a quick ride and it sounded really good. Overall, I'm very pleased with the Scorpion product. The price was excellent, and everything fit perfectly. With a sawzall, this would have been a 20 minute install. :P [/img]
