I think I am going to just upgrade my 2005 Arctic cat 400 auto exhaust and would like to know if there is a direct fit after market exhaust out there. I believe the exhaust that fits the 2004 500 cats will also fit the 2005 400's. Any help with what will fit and best place to buy will be appreciated!!! I would also like to get a quiet core if possible!

Thanks!! RCAT400
