I want to replace the stock exhaust on my '01 Xplorer 400 4x4. I'm wondering what brand would be good to go with? Price is obviously important but the quality is more important. I want a muffler with a spark arrestor (removable if possible) and forestry approved. The only mods I've done currently are a K&N filter and a white Polaris primary spring. I'm more then likely going to be adding 3 grams of weight to the clutch and an HPD Violet secondary spring to compensate for the 26" tires I put on. I basically just want to open up the exhaust for better performance.

Thanks for your suggestions.

 

I ran the Aaen Torquer on my old 400 Sportsman and loved it.I dont know if Aaen has a spark arrestor silencer or not though.

 

pro circuit and big gun are really nice pipes, and both have removable spark arresters and quiet core inserts

 

I dont think these are for 2strokes are they?

 

oh my bad i thought it was a 4 stroke[img]i/expressions/face-icon-small-confused.gif[/img] they also make 2 stroke pipes.

 

i always thought that the fmf Gnarly pipe would be perfect for this quad its built for low end
but has good top end plus fmf suggests stock cluthing and jetting for the pipe thats what i used on my 400 sport for about a year and a half with no problems its also nice and quiet...

 

Thanks for the info everyone. I was looking at the FMF but I didn't know if it would be a good system or not plus I was seeing what else people were using.

 

So I've been looking around on FMF's website and on other websites for a Gnarly pipe and TurbineCore 2 muffler to fit my 2001 Xplorer 400 with no luck. I've emailed FMF a couple of times with no response. They show on their website that the Gnarly pipe and Turbine Core 2 will fit a 2001 Scrambler/Sport 400. Would the pipe and muffler for the Scrambler/Sport 400 bolt on to my Xplorer or not?

 

Would not fit they hook up differintly

 

Alright, thanks. I guess I'll keep looking for new exhaust.
