I just bought an m50 manifold from xsperf through the classifieds forum. haha, I think that's the first purchase our classifieds forum has organized.
I've talked to someone who installed an m50 manifold before and they said it was a very noticable mod, making a pretty big difference in power, but I've never heard any numbers.
What kind of gains could I expect (estimated of course until i dyno one day) from an m50 manifold? I know you lose some low end from it, but I have pulleys waiting to be installed also that will help that a bit.
