If you are going to spend money on looks and performance why buy manifolds?

CMI E-Tops or Sport Tubes are headers with style and performance. Ask about the CMI Unitops as they are priced nearly the same as the other guy's manifolds.

Welded tube headers look the best but cost the most and have a history of developing cracks over time which results in water getting into the cylinders and then hydraulic lock engine damage if not diligently leak tested and repaired when the cracking occurs. CMI's are consistently mentioned as providing the most hp. You only get the rated hp improvement if you run them dry since wet exhaust increases back pressure.

I opted for the Dana Torque Flow exhaust manifolds which are roughly similar to the KE aluminum header dedsign approach ie extended individual internal runner length. The Dana's cost half that of CMI's and with them one does not have to worry about cracking and associated leak testing to monitor for same and repair. They do not provide quite the hp that a set of CMI's would but close enough given the other benefits.

My 0.02.

Because they actually last and don't cause you to spend more money on blown engines when the headers fail.
