Wow...you don't know how wrong you are. Would you like to see dyno sheets proving a difference between a log manifold (same as a stock) vs. a tubular manifold?
S14life...Since the GT2871R is in theory the same external size as a Disco potato, and i believe the stock lines bolt up to that, then yes. I don't know since I have braided stainless lines.

Actually he's right. Considering a stock manifold is not a log manifold and a Megan manifold is not an equal length Full Race manifold, the thread you're about to [attempt] to prove your point on is useless (I'm guessing this was the thread). The same person that started that thread has said on numerous occasions that the gains on the stock replacement manifolds are minimal at best and recommends not using them. If I was wrong about the thread, I apologize.
And the Megan manifold IS a piece of crap. A friend of mine is a rep for them and when I asked him if they'll hold up, he told me they are like every other tubular stock replacement sr20det manifold on the market and they will fail at some point.
