    Default 998 cat delete results question

    Ok, so I tried searching through the various threads and my google-fu failed me.

    For those that have done the cat delete on the 998, what sort of heat improvement have you seen? If you had boiling gas, did it stop? What is the weight difference between stock and the delete pipe? Any performance improvement in acceleration?

    Trying to convince the better half that we need to do this...

    Thanks.

    Looked for the video that a forum member posted on the subject without luck.
    It showed him using a temp gun showing readings before and after Cat removal. Unfortunately can't locate it but the reading before Cat removal was 177°C and after Cat removal 77°C.
    Unfortunately can't help with other queries but am sure someone will jump in soon.

    When I remove my cat the gas smell almost went completely away I could actually park my spyder back in the garage after a long ride. When the cat was on the bike I had to park out side and let it cool off and air out because of the very strong gas smell.

    There was some good performance improvement and I also like the new sound.

    I had the cat removed and drove it about 1200 miles. I reinstalled the cat because I just traded it in on a new 2015. So I have the cat removal pipe for sale from my old 2012 RTL.

    (Trying to convince the better half that we need to do this ...) yes it was definitely worth doing. I asked Len from pitbull Powersports what's the downside and he says there is none and I replied yes the cost (but it was well worth it). I can definitely give you a good price on my if its the one you're need.

    The cat definitely weigh more than the removal pipe.

    Tom, I won't ask about your cat removal pipe but where would one purchase the same and what is involved in removing the cat and installing this pipe?

    The installation is not too bad but you need a hoist. If you do it yourself I highly recommend removing one extra bolt to remove the main muffler it makes it so much easier. On the website it's called muffler removal pipe I believe.

    It can be purchase at:

    Oh one more thing the pipe is stainless steel

    . The cat sits right under the fuel tank. Anything you can do to reduce heat on the fuel tank with the 998 engine is worth it. After I removed mine, I have never experienced boiling gas or smelled fumes again. I had previously wrapped the headers, which also resulted in less heat, but the greater reduction in heat was due to the cat removal. I also experienced greater low-end torque and the slightly deeper exhaust note, but I consider those advantages to be "minor perks" compared to the safety and comfort factors.

    I agree with you 100% I was also concerned about fire hazard from the excessive gas fumes it was well worth removing the cat

    Are you saying the engine needs to be lifted out of the frame to do this (the hoist comment)???

    No I used a hoist to lift the Spyder so I could work under it.

    Thanks for the replies everyone!

    Anyone know what the approximate weight difference is between the cat and the new pipe?

    Just weighed my CAT, it weighed in at 13 lbs. Just a guess but the bypass pipe probably weighed about 4lbs.

    NOW! The oem muffler weighed in at 22lbs. My carbon fiber Two Brothers probably weighed about 10lbs. Just a guess there also as I never weighed the Two Bothers, but it was considerably lighter.

    The surface temperature of my catalytic converter was 378 degree F and the surface temperature of the cat delete is 174 degrees F. That kind of temperature reduction from right under the gas tank sure as hell makes me feel better

    The shipping weight of the pipe that I took off of my 2012 RT is 10 pounds.

    Just had my Cat delete done at Spyderpops. 12 RT.
    better performance
    better sound
    getting about 2 more miles to gallon in fuel mileage
    haven't really noticed much temp difference. I'm surprised.
    Still glad I did it

    I removed the CAT on my 2013. Did nothing to subside the gas smell or any noticeable heat by the rider. It however sounded much better. The real culprit is the front exhaust that wraps around the left side and crosses just under the gas tank only 2-3 inches below. If you could wrap that pipe a lot I would think that would do more than the CAT removal for heat. The CAT is low and will contribute when stopped but once underway the heat is dispersed rearward with the air movement.

    I also removed my CAT (politically correct: primary muffler to make it sound less hot) on my 2014 more for some increase in sound.

    Would I do both Spyders again? YES

    In my experience removing the cat does little for heat (even with a wrap) and very little if any for performance. What it does do is create a lot of noise. I ran timed trials before and after (stop watch) and found no decernable change although the sound made be believe I had more power.

    I first added a Akrapavich muffler and was able to determine a small gain with that (about 1/2 a second in a quarter mile). I went further and installed a fuel controller but no gain. I got a small gain but the computer kept through codes with the entire system in place. The bikes computer seems to allow for the muffler but beyond that it wants to stay within its programed tolerances.

    I also tried adding the air filter upgrade but again, LOTS of noise but no decernable improvement.

    My bike was a 2011 RT and I started working toward power improvements/heat reduction around 18000 k. After repeated attemps I put everthing back to stock other than the muffler. I eliminated the heat through other methods and was very successful in that regard.

    What were the "other" methods to reduce heat?
