I too have the Pro-Circuit slip on.

I was supprised to learn that it does hit the swing-arm. Mine has a very small dent in it way in the back / under.

You are going to have to get some very big air to do much damage to the pipe. I accidentially went off a dune once and flew about 35' with about a 15' drop. I am sure this is where it got bent. Luckily, I was able to land without falling off the quad. Sometimes luck is far better than skill.

I would go with the Pro-Circuit again but, would check out the Yoshi and the CT pipes first. The Pro-Circuit is less than $200 I would guess the Yoshi and the CT would be around $400-$500. Not worth the extra money to me IMO.

I think FMF makes a pipe that is approved for the Oregon Dunes (noise restricted.) If you are concerned about noise at all. It is the Q series. I am not sure if they make one for the DS yet.

Whatever you do make sure the pipe is USFS approved Spark Arrestor. A few pipes do not have the spark arrestor and you will not be able to ride in many areas without it.

 

I rode a DS with an HMF and it seemed strong.

 

don't worry about having the spark arrestistor, i ride in private places, there is no public riding areas around here

 

The Yosh is a ok pipe, customer service is very bad wish I did not have mine.

 

I've had good results with my Pro Circuit T4. Looks good, nice increase in lowend, sounds great, and doesn't cost that much (compared to some other pipes).

 

MadBaja819,

I read you purchased the 14" FMF Titanium-4, I really like that one but am worried about the noise level. Can you compare the noise of yours to any others? I hate to go to the 17" for noise level but loose on the power. Plus I really like the size of the 14", small, dosen't extend past the grab bar or hit the swingarm. I really like the looks also.

 

Bomb threat I have a procircuit t-4 also and it does hit the swing arm because you can see the dent and where the swing arm hit the pipe. it isnt a very big dent but just filling you in
