mtnbob Posted February 16, 2007 Share Posted February 16, 2007 1997 outback 2.5 auto 260,000 miles. i have a crack in my manifold, and figure I might as well replace it(been driving it like that for 40,000 miles). I see performance manifolds all over ebay and was wondering if they are ok, or i should stick with stock. They say they give more horsepower with a little more rumble coming out the back. Any suggestions would be greatly appreciated. mtnbob Quote Link to comment Share on other sites More sharing options...
