Sounds like a logical place to start.  Thanks so much. Jon

My 2017 Challenger 550 recently started displaying the opposite blinker than dash switch shows.  If I turn R blinker paddle switch on it’s actually the L blinker that blinks and vice versa.  Any ideas?   Thanks.  Jon

My steering suddenly has gotten extremely hard to turn.   Any fuses, fluid etc that are logical to check first?    Thanks.   Jon

Yea mine has the same open rubber elbow.  I had posted a picture in one of my first posts asking if that my be my source of fumes.  No one seemed worried about it and asked if warm air is coming out which it is.   So I assume it’s normal.   Jon

Put in neutral before shifting to 4wd.  
 

johnny L did you get the Noico material installed?   I got mine delivered this week and will try to install tomorrow.  My exhaust gasket was lost in shipping so I reordered from Cub.  Jon

So I did find multiple leaks on my exhaust pipe, and muffler.  None were easy to see until pipe was removed.   I’ve epoxied them with high temp stuff and will try today to see if it’s taken care of the problem totally.  Parts seem hard to get.  I’d ordered exhaust manifold gasket from supplier on this forum, but it’s delayed delivery at least a week from projected delivery date.   Thanks for the replies.  Jon

In an effort to solve my cab noise and exhaust fume issue on my 2017 550, I’m trying to remove seat backs to apply sound dampening material.   Do the phillips screws from the back window hold them on?    Jon

Bolted. 

Let me know how it does.   After your post I researched youtube and went to 3 bigbox hardwares to get self sticking aluminum insulation roll but nobody had.   I do have an exhaust pipe gasket ordered to see if that cuts down exhaust smell.   Jon

So I ordered a new exhaust pipe metal gasket from the helpful link/parts schematic on this forum.   We’ll see if this helps with exhaust smell.   I’ll also try to insulate and sound dampen under seat between motor and cab.  

And did that seem to help with exhaust smell and/or noise?   I sure appreciate the info.  Jon

Yea I agree.   I thought it was uncomfortable to operate.   I took pedal out and drilled holes in it to attach metal plate that I shaped to extend the pedal.  That helped but I still ended up putting a board under pedal to rest my heel and elevate my heel and that’s helped more.  I’m not short, 6 ‘1/2” So I don’t understand who these are designed for.   Jon

Can you get them at auto parts store?

Nope not familiar with smoke test but will research.  Appreciate it.  Jon.  Does the exhaust manifold have a donut asbestos type gasket that would be easy to replace?   

I did tighten exhaust manifold bolts but didn’t remove to see if needs new gasket.  Think I will remove today and replace gasket.  I assume they are readily available at auto parts stores.  I visited a Cub Dealership yesterday hoping to look at other challengers to see if they had same problem.  But the dealership only had cub mowers.  I bought mine from private party.  Appreciate the replies.   

Here is a pic of rubber elbow not attached to exhaust.  I don’t see anywhere that it’s supposed to attach, warm air but not exhaust smell is expelled when running.  Don’t see obvious leak in exhaust or manifold but does have overwhelming exhaust smell.   Thanks Travis for responding.   Jon

Had this UTV 1 week now, previous owner had put windshield and back window on, has half doors but no windows.  Is there a simple fix for exhaust fumes in cab, tailpipe extension etc?    Thx so much.   Jon

Just bought this used 550 last week, complete newbie btw,  i find the gas pedal cumbersome to push down and hold.  Seems to be lots of clearance from floor and I can’t rest heel on floor.  I’ve seen pedal accessories for sale this this must not be a unique problem.   What have y’all done to improve?   Thx.  Jon
