To the ones that have done it, does the 'cat delete' make that much difference in heat over a stock unaltered muffler?
Also I was wondering if something like the Desert Craft CVT Blaster II would be needed for my style of riding, I mostly ride Forest Service roads and the small gravel roads and not wide open but at a decent pace. Thanks for any info.

I think it makes a big difference in the heat generated.
I don't have any scientific proof but I don't think my fan comes on as often since i did the cat delete.
I also opened up the aluminum shield behind the muffler to let heat out.
I would never run again with a cat

185EZ..... I agree totally. I run the trinity stage 5. So I deleted the heat shield as well. I believe it’s a lot cooler than stock was.

Huge difference. Last weekend never topped 180 degrees during a 100 mile run. I’m not sure the fan ever came on. Now it was only 65 outside so I’m sure that also helped a ton.

There's a you tube video that shows just at idle for 10 min 32 degrees cooler at turbo 64 degrees cooler at muffler where the cat was. I gutted mine yesterday. I followed the video, instead of cutting the pipe I grinded the weld at the 90 and it slipped apart. Made it easier and stronger to weld. Took about an hour start to finish. I wish I would have done it when new.

I have watched all those videos and believe I'll do the cat delete today if I get time. I will see if I can do it like you did and grind the weld. Thanks guys for the info.

wrknman is correct. Take a little more time and grind off the weld. The pipe slips into the muffler.
I wish I would have known that when I did mine. I was grinding on the weld to smooth it out but didn't go far enough.
I've seen guys leave the muffler on and do all this but I took mine off to make sure I got most of the cat guts out.
I use a spark arrestor and it still had some debris in it after a ride.

I didn't think about it but I guess I should wait for the Warranty to run out before I do it.

I did mine with 3 years left on warranty. You could always look for a stock muffler later to change back if needed. I see them on the Craig or facepage for cheap

I did my 3 weeks ago. Notice the turbo fire red after a ride. Got scared since I’m new to this UTV world. I came across the cat delete. Video And so I did it. Cut it open and cleaned out the cat. Turbo seems to run more efficient and cooler and it doesn’t not get fire red like a formula one test engine anymore. You also slightly hear the turbo out if the exhaust And it’s not loud but. But better than stock. Saved myself from over priced exhausts.

I have a stock muffler and one with the cat deleted for xpt. But shipping would be outrageous. And I have no clue what one is worth.

My brother and I each just recently purchased new turboS's. I took the pussy out of my stock muffler asap and he still has his. On every ride my engine temps are always 10 degrees cooler.

I had 50 feet on the odometer when i made my first RZR turbo mod and threw away the cat. i knew i didn't need a muffler glowing red as well and could only help with getting heat out of the engine.
