Over the weekend I test fitted the new Stage II silencer with the Evo header on my race car. It fit almost perfect. The muffler only needed a minor tweak to the tailpipe for a better fit to the valence.
Today I finished installing the guts in the muffler.
I just have to do a sound test and get some dyno results to be completely satisfied that I have a winner.
Here's a look.

You are a craftsman.. look at the collection points on that thing.. what a spider!

Chris, I have to ask man... how much do you charge for a similar flare job, as what you have on your car? Ball park..

When it was on the right side everyone thought it was on the wrong side.
Now that its on the left side you think its the right side.
I live in a topsy-turvy (914) world.

Hows the search going Herb? or are you waiting for the severance to run out?

Chris: show a picture of the muffler/quiet can. Does everything bolt/fit into the stock location for the muffler?

I'll take a picture of the muffler later today, after I finish welding it. When I did the test fit it was just a hollow tube, that's why no pic yet.
The bracket is permanently attached to the muffler and bolts to the two studs on the back of the tranny. I believe that there is no (or minimal) interference with the stock heat shield.

VOW !! What a good looking system !!!

I would nearly like to say that, what a pity I have a six. I would love to have that kind of header & muffler.

100% Stainless, including the packing material.

Here's an install view, no valence this time.

One more look, from the end. It looks like there is NO interference with the stock heat shield. It just clears cutout in the the valence.

Nice..

Chris will you still make one of your phase 9 clones for we who dont drive 4s?

I mean just the muffler

You could probably talk me into it Tim.

I'm working on having the stainless pieces cut out by a local water jet company instead of me cutting them one at a time with my plasma cutter.

I've switched to flanged attachments for all my header/muffler connections.

V-band clamps work really well for exhausts, i know they also add a few buck to the bottom line

I'm adding this view of the header to help show clearance for anyone using a rear sway bar (especially Tarrett). It doesn't quite show clearly enough how the pipe drops down once it is behind the halfshaft. I think there is plenty of clearance though.
The header is kind of close to the trunk floor for a short distance, and I have to relocate my starter wires (which currently come in from the side) before I install it.

That's gotta be one of the craziest header systems ever! I LOVE IT!! Can't wait to buy mine.

Posted by: crash914 Jun 2 2005, 04:57 AM

Hmmmmmm....looks like adjusting valves will be fun....Can we get a nice heat shield to cover up all that stainless?

Just kidding...looks great!

Any idea of how the performance will compare to your current set up?

Valve adjustment is easy. The header does not interfere.
I just got through doing a valve adjustment on a '75 with stock HE's. That was a major PITA!
The only place I think a heat shield might be appropriate is between the trunk floor and the secondary collector where it is about an inch away. That is, only if you have anything perishable in that part of the trunk.

According to Jake Raby, who compared my original 912E header to my Evo Beetle header on a 2.3L with peak hp around 6000 rpm there was no performance difference. I expect that the higher the rpm peak the more my Evo header will outperform the old header, due to more equal length primaries and meeting the engineering design lengths within specified tolerances.
An Evo Upright Conversion (Beetle) header was used on the dyno runs of my new FP engine with impressive results.
