I say go with a ported stock manifold. As for the O2 that is up to you. IF you want the neighborhood to know when you are in boost then get an external dump. If you are looking for something a little more quiet yet effective then go with the megan or the invadia. I would lean toward the invadia if you plan on going to a red or black set-up.

 

the rev2 is an intake manifold not exhaust mani. I have the shearer tubular mani. lot more money but worth the results in my opinion. exspecially if your going to upgrade the turbo to an fp green, red, black in the future.

 

Sure about that? Its right in the URL. Rev2 is a title they have given to both intake and exhaust manifolds.

yeah, the ported exhaust mani is labelled PEM. Not rev 1,2,3. I have the rev3 intake mani. I didnt see exhaust mani's called rev2 or 3. Maybe they could chime in.

 

I also have the Rev3 intake manifold (my car is the one it was prototyped on actually) and I was present for the ported exhaust manifold prototype testing. Like I said, look right in the URL or the name across the top of your web browser. In the end though, I'm not going to get into a pissing match with some newb about the name of an exhaust manifold since its the only one MAP makes for the Evo 8/9 anyway.

 

yeah not worth it. been in my evo since 04 though, dont have too much time to play on the internet.

 

My apologies for calling you a newb then

 

I have the Megan manifold which I think is over looked and the map external o2 dump is the perfect balance of price and quality...and on sale for 264 shipped.

 

megan manny is crap it cracks etc but not getting into that

 

Here's a link to the Megan Racing manifold dyno->

For the price, you can't beat it. Just make sure your O2 housing is still mountable to it's bracket. There's also the weight reduction advantage.

 

full-race is the best when it comes to aftermarket tubular manifolds

 

The Megan is not the best on the market but I have had mine for 5 months in a harsh climate and have had no problems with it.

 

just wondering, how much it would cost to port out the stocker?

 

Thanks for the kind words guys! In regards to the nomenclature of our exhaust manifolds at one point we did refer to them as Rev2 (full porting without cutting / rewelding) but it was confusing my team and people were receiving intake manifolds when they paid for exhaust manifolds! lol Now they are just ported exhaust manifolds

In any case, for the OP I think your original plans to go with our manifold and O2 dump is a great combo. Plus, you can't beat our sale pricing on the O2 dumps

 

looks like ill be going with the MAP setup
