And after waiting for GAWD only knows how long .. us MSP's now have a choice between THREE new aftermarket exhaust manifolds!

Brought to you by Focus, this manifold IS NO LONGER IN PRODUCTION. It came with a few different options. The following info was copied and pasted from Focus's thread.

The manifold specs are as follows:
3/8" Turbo Flange (Steel)
1/2" Flange for head (Steel)
1 5/8" I.D. Tubing

Pricing:
Base Manifold Price: $439 USD with O2 Bung
EGR Tube option: Add $20
Ceramic coating: Add $55
Stainless steel option: Add $250

$100 deposit for the manifold is required, the rest is to be paid when the finished product is ready to be shipped out. A picture will be taken with the manifold and the shipping label as well.

| The Second |

From Thunder Exhaust-Muffler in cooperation with Protephile, it's a direct replacement for the stock manifold, including the O2 sensor and EGR. IT IS IN PRODUCTION. Everything that plugs into your (cracked) stock manny will hook right up to this one. There are no 'build options' -- all manifolds come as indicated.

The manifold specs are as follows:
Material: SUS 304 stainless, 2mm thick.
Chromed steel flanges.
EGR and O2 included, lined up correctly.
Tig-welded from the inside of the flanges and support welded on the outside as well.
Warranty.

**** Issues of cracked welds found in V1 of this manifold have been addressed for V2! Manifolds that are currently being produced have had NO reported problems!

Price is $400 shipped with 6-9 buyers. Price will drop to $375 shipped with 10 buyers. Please see the CURRENT GB thread listed below for further details.

First, thanks to Rush and her superior organizational skills.

In answer to a few of your questions:

This will not be a one-time only production run. However, I expect the initial
Group Buy will generate more units than subsequent Group Buys. I am basing your price on 15 presold units because I am pretty confident that number can be reached. I'd figure at least a 10-15% increase in price in the future.

The welded piece between runners one and two, which I did not notice initially, is to support the longer-length of runner number one so it won't
sag under stress and possibly crack the weld. Thunder has always been clever
about their designs.

If anyone else has any questions I'll be happy to answer them.
