395xp muffler mod question

[Ambull]

I have a late model 395xp that is stock, and I would like to try and mod the muffler on it. The exhaust deflector has what appears to be a restrictor mounted to it. Does that have something to do with EPA? If not, what is it for? I guess the easiest mod would just be to cut that restrictor off. Also, any other tips would be greatly appreciated.

Also, I apologize in advance if this topic has already been covered. I did try to search for an answer before posting.

Here are some pics of the muffler:

No, it's bent forward if you look closely.

Carb tune?

Just tune it as you would normally.

Another thing you guy's could do is remove the base gasket and replace with some suitable sealer or copy paper. Not a difficult nor time consuming job.

Use the 288 deflecter

The part I ordered does not look like it will work it is 288 deflector part 503 58 99 01 and it is slightly curved on one side so it won't mount to a flat muffler, doesn't seem right or look like your pictures. Maybe the company sent the wrong part? I don't know let me know your thoughts if its wrong I will have to call npec and get it corrected, or do you guys just flatten the deflectors out before using them? Thanks

just flatten the deflector out and install
