Our new tubular stock replacement exhaust manifold is made of high quality mandrel bent SUS304 stainless steel and electronically tig welded at all joints. This manifold was designed to retain your factory turbo orientation and is backed by a full one year warranty. The shorter length runners help to increase spool while still allowing for big power gains up top, you will not find a higher quality manifold for the price.

Limited time introductory pricing is $449.99 Shipped
(Advanced Ceramic Coating Options Are Available for $90)

I am using this on my FP Black setup and love it. Great piece at a great price!

Looks nice. How does it compare to the ported stock manifold in spool and peak power?

Do you have any installed pics sir? That would be great!

We brought two of these in for testing and before we could even get them installed on a test car they were sold! I would really like to know this answer as well, I'm expecting decent gains throughout the power band without a significant affect on spool

Yeah, I happen to be one of those guys that snagged up this beautiful piece of hardware before they hit the shelfs. Here is a pic after about 1500 miles on it. It turned an awesome multicolor like on many motorbikes. As far as how it compares to stock ported mani, I could not say but on my 2.3L that you guys at MAP built for me, my FPBlack seems to spool very fast right near how my FPgreen on my old 2.0 did with the stock manifold. I love it! I put down 510WHP on MAPs dynojet at only 26psi. I have to get may car back down there to get the final tune and turn up the boost now the motor's is broke in. I can not wait to see what she'll turn out!

Check out the Dyno and more of the build and pics here: https://www.evolutionm.net/forums/ev...o-build-2.html

This is a must buy for any stock frame turbo with the price/performance.

Good luck and happy sales!

Nice, definitely interested after some more before and after dyno sheets start popping up.

Wow, great work MAP. Very interested to see some results using this piece.

Affordable + gains = awesome!

I like it but how much is lost with not having equal length?

ChrisCarey

iTrader: (38)

There are differing opinions out there, but the general consensus is that on a twin scroll application equal length is of little importance as the companion cylinders fire 180 degrees apart negating the benefits. And if you notice the companion runners are of similar length so there should be little interference between the pulses.

Additionally, anyone that would be able to have some before and after dyno testing performed with this product please contact me as we are willing to offer a substantial discount for your efforts!

So the Equal Length is better but you wouldn't lose sleep over it?

ChrisCarey

iTrader: (38)

The purpose of equal length is to keep the exhaust pulses evenly spaced for the best performance. When dealing with a single scroll application you have to deal with 4 exhaust pulses potentially interfering with each other, while a twin scroll application only has two exhaust pulses per scroll that are 180 degrees apart. Until I see testing that proves otherwise I am sticking to my opinion that equal length manifolds on a twin scroll application are unnecessary.

I see a trend here!

The o2 housing is half the price of the manifold. I don't understand that.

I just changed the O2 housing price to $174.99

I would agree with this on a Stock VIII or IX turbo but not the bigger FP models. I bet the equal length units would help on topend as shown with the Full Race Unit.
