The problem with that is the sound comes out 360 deg. and it would be directed right back at you. I was thinking of running a j pipe and another j pipe so i could get it to come out under the middle of the tail lights. I would end up with a big long s between the cat and the supertrapp. I actually bought the pipe with the supertrapp I just haven't decided if I want to keep the cat. If I do this the O2 sensor on the in side of the cat needs to be moved to the first pipe on the header and the O2 sensor passed the cat needs to be moved to right before the supertrapp.

I imagine the O2 sensors are use to check the function of the cat and get different reading and the computer adjusts the fuel air mix accordingly. Losing any of set may effect the operation because the computer know what it wants. I would check with some experts before taking anything out.

From http://en.wikipedia.org/wiki/Catalytic_converter : In vehicles with OBD-II, a second oxygen sensor is fitted after the catalytic converter to monitor the O2 levels. The on-board computer makes comparisons between the readings of the two sensors. If both sensors give the same output, the catalytic converter is non-functioning, and must be replaced. It will also spot less serious damage to a catalytic converter, such as the use of leaded racing fuel in an on-road vehicle.

I talked to Clint at No Limits Power Sports and he said off the record of course to loose the cat. The locations for the O2 sensors I spoke of before is where he told me to put them. He said to get them as far apart as possible. The O2 before the cat should go in the farthest forward tube on the header the O2 sensor after the cat should go just before the muffler. This is what he said he would do.

Hey guys.... I had 2 of my customers use a 90 off the tail pipe, then a 16 or 18 in. glasspack. Like a cherry bomb.... swept behind the radiator , then another 90 to kick the noise out behind the machine. No loss in performance, and dropped the noise level to a nicer "note". Just an option. A.

I have a new muffler for mine, just have not had time to put it on. This last week-end while camping i looked at the cat and said what the hell. Took a socket stuck it on the end of a extension and let the hammer rip. Knocked the cat out with the cat still on the engine. It seemed to help the top end, had the engine against the rev limiter in high gear. It is louder now, but i think i might just put a baffle in the cat so it looks stock . It did not hurt the bottom-end, I think it made it better, but it is hard to tell because of the sound of the engine.

You know what, i think the fuel millage went upwith the cat out. The new fuel tank pick-up worked great. I had about 20 jeeps and i dont know how many other utvs watch me go up the side of this mountain. These things are like a billy goat on hard pact. no one else tried going up the hill.

      2021 Hisun Axis 500 No Start - Need Help Please
      By Hunterman22
      2021 Hisun Axis 500 UTV (From Lowes)
      Will NOT START
      MY apologies if this is to much info just wanted to give yal the most information possible for help.
      I'm a so called diyer. An Electrician by trade 21yrs. I got my S×S from my last job. The contractor purchased this S×S for this specific job brand new, from Lowes. They used it for hauling materials, tools, & a little bit of anything you can think of on an Industrial type job site. 
      I remember getting on the SxS one time & pushed the gas petal all the way to the floor & SxS had very little power. 
      So anyway ,when the job finished up back mid July this year (7/2024) , I asked the contractor what they was going to do with it. I was told to take it. Otherwise it would go to the contractors yard (storage yard) & most likely rust away. 
      Took it home washed it , it had a heavy coat of dust on it & in it dust was every where. My helper & I had to push it on the trailer to get it home.  After washing it throughly I let it sit & dry out for a good day and half, maybe 2 days. Before trying to start it. NO START. Will turn over & try to start but thats it. 
      So here's what I've purchased & installed. New Air Filter, new spark plug, new air idle control valve (AICV), new throttle position sensor, new throttle body, new oxygen sensor, new digital dash speedometer/fuel gauge/clock. 
      Also drained the old oil & gas & replaced with new oil & 93oct. gas. I should probably mention that I've changed the AICV twice. The 1st time I changed the AICV I was able to get the SxS started & let idle for at least 10-15min. Drove out of the garage, with very little power,  turned it around & barely got it back in the garage.That was the one & only time I've been able to start the SxS. I've also cleaned the Throttle Body and & intake with TB cleaner.  So after that the AICV was  making weird noise so I pulled it out & tried cleaning it, pretty sure I messed it up. So I purchased a Throttle Body that came with new AICV & TPS. Still NO START.  I've checked the fuel pump & the fuel injector.  I took the injector off still hooked up to wiring & turned the key over, the injector sprayed a lot of gas out kinda the size of a volleyball. I've also checked the clearance gap on the intake & exhaust valve. But today 11/2/2024 I'm going recheck spark plug gap & the valve gaps. And alot of other checking. Would the driver side seat belt have anything to do with it not starting?? I know the driver side seat belt has to be in gauged for full throttle "going fast". Thing is the drv. side seat belt will latch but feels like might be messed up inside of it. Tired opening it up but to no avail.  I've never had a S×S or 4wheeler so I was really excited when I got the S×S,not so much anymore.  I work on & fix my own vehicles usually no problems.  But this SxS is kicking my ass.
      So if possible & someone could help me with some ideas or tell me what Im doing wrong or did wrong, I would greatly appreciate it.  Thank you for reading thus far.

      Want a new work UTV; who and what should I look for?
      By FTG-05
      I want to ditch my Kubota RTV-XG850 and its moronic twitchy throttle design flaw, get rid of the problematic engine and the 40 mph purposely throttled speed.
      So far, I'm looking at the Honda Pioneer 1000 and the Polaris Ranger 1000, both of which have 1000-1500 lb payload bed capacity.
      What other makes and models should I be looking at?
       
      Thanks for the help!
