Re: Headers Vs. HP Manifolds
Has anyone heard of these manifolds. I spoke with the manufacturer and was told they are aluminum, have individual runners, coated on the inside and will bolt right up to the factory risers. I have a 7.4 MPI looking for a little more low to mid range power. What do ya think?

The cutaway shows individual runners, but you would know better than I. Dennis told me they would improve power slightly but not drastically. I think the weight savings might be worth it. I added three extra Optima batteries and I am just trying to make up for the extra weight. Worth the money?

You may want to consider doing a search here in the tech section on Dennis Moore's manifolds. Someone on here bought some and the quality was lacking, missing harware, as well as poor customer service.

Re: Headers Vs. HP Manifolds
I appreciate the feedback. I think I am going to hold off and spend the extra money on a set of proven performance manifolds. I am not looking for a big gain but just a little better performance out of the hole. I have a 26' Envision open bow and it is very sluggish when full of people and coolers. I am not sure how much a set of manifolds will help the 7.4 mpi. All I have done to this point is a K&N filter. Who makes the best bang for the buck when it comes to manifolds.

I have always known the Stainless Marine exhaust system to be pretty reasonable, but there are several aftermarket systems available---even more than what I have listed. Maybe some of the other guys can chime in who have had experience with other manifolds.
