i was wondering if the muse 02 dump works good with my full AMS exhaust on my evo 9 (http://cgi.ebay.com/ebaymotors/Muse-...ht_1492wt_1165) also do i definetly need to replace the gaskets and if so which ones while changing?

 

bump!!

 

It sure will! It bolts right up to any exhaust that bolts up to them OEM o2 housing

Also includes the turbo to o2 housing gasket for the divided outlet. You may wanna pickup a new donut gasket for the downpipe if yours is worn out though.
