why do most people on here prefer a tubular manifold to something like the inline or drag manifold
i have seen comparable manifolds from both sides posting similar numbers and was wondering what would be best for a street car. Which ones crack easier and spool up the turbo better.

tubulars tend to spool turbos quicker and have better flow but are known to crack unless you purchase something like like a full race manifold

The Tubular manifolds Offer an overall Better design suited for better Flow Characteristics. Some of the Cast Shortie manifolds Still work off of pressure as a simple log manifold would.
Tubular manifolds Depending on the design generally spool a bit later compared to the Cast/log manifolds but offer overall mid range and Top end power gains.
The lastest manifolds on the market Dont crack with the Thicker tubing craze.

What? Maybe you haven't seen the Full-Race dyno test comparing log vs their manifold where the turbo spooled about 500rpm later than with a log manifold. You should check it out. I always thought it was kind of funny seeing all the EL manifold makers charging $800+ on manifolds and never spending a few bucks to dyno test their product. Not only that but they make claims that later proved by their own testing was 100% false.
As for your cracking nonsense, when welded correctly, braced correctly, and constructed correctly a manifold will not crack. Thats the reason why your infamous honda-tech manifold makers dont have problems because most of them take pride in their construction and customer support. Its their product testing that needs work.
As for the reason why people chose a log manifold vs a EL manifold the answers are simple. Topping the list is price. Then second comes fitment ease. Third comes to the fact most people on this site want approx 250-300whp in their car and cannot justify buying a product that is basically made for serious "race" cars. Somehow they've found their way onto your average grocery getter which I never truely understood, but if it makes you happy who am I to say?
