• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage.

HowTo: 2019 RTL - RLS cat/primary muffler delete install with pics

As promised by Ricky (RLS Exhaust), my RLS cat delete arrived today. When UPS updated its delivery ETA from 1:00-3:00 to 3:00-7:00, when work stopped at 4:30, I figured I'd at least get the bike jacked up while taking my time about it, since I never had before.

Front tires: super simple, just ride up onto the ramps. The right one slid just about an inch, but I was firmly on the flats of both, so I figured I was good. (My garage concrete is finished, so there was a little bit of tire squeal, but nothing too scary.) I DID remember to turn my Pedalbox OFF before trying any of this.

After surveying the clearance with just the front wheels on the low-profile ramps, I figured it would help to get the back up a bit. I don't have a fancy lift, just my trusty small floor jack. So I got a block of wood and put it as far back under the center frame as possible (as shown) and jacked it up. To the newbies like me, this is a little unnerving, as the jack seems way too far forward. But since all the engine is in front of it, it works, as you are still behind the balance point of the bike. There was a very, very slight shift in the front wheels as some of the weight was lifted from them, but the rear wheel came up as expected.

So then I put a jack stand under the rear shock mount, protected by a rag. (pic) However, after examining things, I realized the jack stand would probably block me from pulling the cat front tines out of their rubber grommets in the frame. So I replaced the jack stand with the wood stack as shown.

After getting the jack out from under the bike, I gave the whole thing a pretty good shake back and forth and forward and back; and I was comfortable I was safe under the bike now.

Then I sprayed some liquid wrench on the muffler clamp bolt and let that set for a bit. When it still wouldn't break loose with my short 13mm, I used the rubber mallet to help persuade it to break loose a bit, then the rest was easy. Once the clamp was loose enough to move to the muffler side of the pipe, a whack with my hand broke the joint loose. Then I used a rubber block in between the tail of the muffler and the bike to keep the joint between the cat and muffler open a bit.

Then the tricky part. I knew RLS was sending a spring puller tool, but I wanted to get this thing off. So I used some thin nylon rope and a large dowel I had to loop through the end of the springs, and then used a boat-cleat style wrap on the dowel to lock the rope around it. Then I tried just simply pulling the spring off the hook. I think a stronger, younger man could have done it, but I could not one handed. However, I quickly figured out that I could wrap up enough rope slack and find something on the bike to wedge one end of the dowel against, and then I could use the dowel as a pry bar to pull the spring. Viola! All three springs removed quite easily.

Then a little 'heel of the palm' to the cat, forcing it straight towards the back wheel, while pulling down a bit, and the top prong pulled loose. Similar for the bottom prongs, and tada! The cat was out!

The next pic is of all the tools I used for the removal.

I wanted to see how much weight savings I would have, so I weighed it. 16.0 lbs flat.


As I was headed upstairs to post this while waiting for UPS, the doorbell rang, and my new toy arrived! Right on time! One hour has elapsed so far, and I was going very deliberately and slowly.

Next post is the install...

The install:

The new cat delete was very well wrapped in bubble wrap. Inside the box: The cat delete itself, the baffle, and the spring puller. But alas, no directions. (I think none should be needed, except maybe the baffle. See below.)

First, I weighed it. 5.0lbs flat. So 11 lbs of weight saving!

Then, I wasn't exactly sure how to install the optional baffle supplied. Since it supposedly helps with backpressure and noise abatement, I wanted to use it. A quick video search on youtube found Ricky's video explaining the cat and baffle and showing how to install the baffle into it. Come to find out, he ships it with the lockdown bolt reversed, which is what confused me. A few minutes later, the baffle was installed, and I was ready to install the cat delete. (Edit: I removed the baffle a while later at Spyderpop's suggestion. It didn't much noise difference.)

Then, I sprayed each of the three rubber grommets for the install tines with some glass cleaner (a youtube trick I learned while preparing for this project). And I got the bottom two started, then the top one. Easy enough to wiggle the whole thing into position and get it lined back up with the muffler pipe. It does seem that the exhaust pipe into the cat delete has a little more angle to it at the front joint than the OEM cat did, as I feel like that was a perfectly straight shot, but maybe not? I don't think it's too alarming, as it's only 1-2 degrees of angle now, and it seems sealed all around.

Then, I replaced the muffler clamp back where it was originally, using the "clean" section to tell me exactly where the clamp previously positioned. Then I tightened it down snug, but not tight.

Then the springs. This was the hardest part, but still not that hard. My biggest challenge is that I need pretty strong reading glasses to see anything closer than about 2-3 feet away, and I was much closer than that, and my glasses kept slipping down my sweaty nose. And the top spring (the one between the pipe and the bottom of the bike) had fallen completely off while I was moving the cat delete into place. However, I eventually was able to move my head far enough away, get my head and glasses positioned correctly, and also get the spring back onto the pipe by feel, and then found I could use the RLS puller with one hand to pull the springs far enough into place if I positioned myself right, and use the other hand to force the spring hook down over the metal loop. Easy enough!

Finally, I removed the block wedge I had holding the muffler away from the body a bit; and I jiggled everything to check for fitment. Then I cranked the muffler clamp bolt down until it was "tight enough" (ie. I couldn't hand crank anymore.)

Installed!

Total time, including 20-minute idle time afterwards, was less than two hours.

Update: I rode the bike a lot this weekend in 100 degree (F) heat in Texas. There were zero problems, and a very noticeable heat decrease on the legs and coming up through the bike at stops! Very happy about all that! However, while I think the pitch of the exhaust lowered a bit and got throatier, I really don't notice much if any of an overall volume change. (This wasn't my primary goal though, but I was looking forward to it.) And it seems like maybe I've lost just a little acceleration already, so I'm hesitant to take the baffle out to make it louder. I might start saving up for an exhaust next! I have a 5 day trip planned starting July 4th, and will provide any new updates noticed when I return.
