• 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. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Guys, guess who was playing with upgrades and recording videos??? RLS is on TheBeast and here is SOUND and PERFORMANCE test
unboxing and also Mounting with few "tips"
Tons of work done, and I have not said the last word yet... :)
 
I like the RLS with the akrapovic....if you notice there's no loss of torque power in 3rd gear with the RLS....I'm glad you're running it WITHOUT the added baffle...
 
will it hurt?

I'm with Martin, I run the RLS with the stock exhaust and no Baffler on my 2015 F3S and love it, my butt dyno noticed no decrease in performance and my mpg went up. Little video going through the tunnels on Angeles Crest Hwy.

I'm running the Exact same setup.. Akrapovic Sinister..RLS cat delete no baffle...and a Stage II remap...it sounds great.. a nice rich agressive sound...and the horse power to match.
 
For those who have stuck with the stock muffler, and just did the cat delete, do you notice more exhaust fumes? I ask, because I tried this scenario and my wife and I both noticed more fumes. I sold the delete pipe, put the cat back on, and then went with an RLS Punisher. Really like the sound now. Just curious what you've experienced with the delete pipe.
 
Yes I did note that issue and not sure why. All connections are tight and seems to seal. No Idea why
 
Kept the cat and replaced that gawd awful looking/sounding original muffler with a Two Brothers Racing S1R slip-on.

LOVE the looks and sound.

Thought about the cat delete, but went the easy way out and ended up with results I’m happy with.

Yes, we've had the same experience. Stock muffler, RLS cat delete, Monster stg 1. Smell the fumes at times around town. Wondering if the RLS substrate baffle would clean up the exhaust at the expense of performance? Haven't tried it yet, because I'm not too keen on drilling a mounting hole in the pipe for mounting.
 
OK....so we weren't crazy when we thought we smelled the exhaust fumes with the delete pipe on. I really wanna go back to the delete pipe for all the given reasons, but I don't wanna deal with the extra fumes. Maybe if RLS or Lamonster figure out how to eliminate the fumes, I'll jump back on the bandwagon. For now, we really like the sound of the RLS muffler and stock cat pipe.
 
I was at Ricky's house today getting a new RLS Exaust. Love it! Since Martin did his video, Ricky has been very busy.
The subject of Martins video came up and I made a comment that all the comparisons and none had the RLS cat delete with one of his Slip ons. He was very impressed with the video so don't be surprised if a Twin Kaos doesn't show up on your doorstep Martin. Just saying, You may have to redo your video soon.

hehehehe, i am happy for Ricky. what i have found out, that works the best is to be honest in your videos. I dont play games, I will not make a good video review about you just because you give me something for free. From Ricky I have bought the cat delete, coz he had explain me the situation of his smaller shop. so I am supper happy that good solution is visible now!!!
plus he owns me a beer for every one cat delete he sells because of my video :) - i am not sure he knows about this condition, but... maybe you can tell him :)

I have a Baldwin cat delete, and yup, I too also get the occasional fuel smell. Just think it's the nature of the beast when eliminating the cat :(
