So i am upgrading minor pieces on my stock 454 mag mpi. i installed a Procharger M1 intercooled unit and will be running 5# of boost. fuel system is upgraded also.
my next question is manifolds... I know its not much but the more flow in the more flow out, i want to keep my silent choice exhaust and dont see much point in not as its only a 650ish hp build not a big motor at all. I am torn between EMI and Stainless marine, is there any real difference between the two for my application since i am restricted to a certain riser to maintain the silent choice? the EMI are about $500 less for same setup.

suggestions??

Go with Stainless Marine 5 year warranty !!

Call Scott at Speed and Custom Marine may have some scratch and dent s too

I have had the EMI and they are good for what you are looking for. Stainless has an impeccable reputation. I've used the Dana's with good results. I think you can save some gas money with the EMI's

stainless marine. call jerry in FL at stainless....

Stainless stands behind product go with them!

I have no experience with EMI but my Stainless Marines have been in my current boat since at least '96 they still clean up & look like new!!

I suggest the EMI. I have no complaints and have them for 3 years now. They have a 3.5 "inner pipe, better for higher hp motors. I have 2 sets on my fountain. They also come with a 5 year warranty.
