New header and exhaust
I picked the car up on Friday. What can say other then
. The new header/exhaust combo feels and sounds great. We have yet to put the new system on the dyno but my highly calibrated butt tells me it is working great.
The first cat back was to large and we were losing to much TQ down low. The high end was great but the sacrifice down low was unacceptable.
The new system starts off at 2" 1/2" coming out of the collector into a high flow cat then into a flex joint. It then runs down the tunnel were it go's into a 2 1/2" ID strait threw resonator. From there it runs into a Y collector that takes the 2 1/2" and splits it into two 2 1/4" pipes . From there it runs to each side of the car were it runs through a 2 1/4" strait threw muffler (one on each side). From there it comes out of the mufflers (still 2 1/4") and runs to the stock exit point.
The Milltek uses 2 1/2" and 1 3/4" so you can see how this system at 2 1/2" and 2 1/4" can flow more air.
The entire system is all mandrel bent stainless. I love the sound. it is deeper in tone then my OBX/Milltek. At cruising speed it is very mellow with out any drone. When you stuff the peddle to the floor it gets real aggressive and sounds amazing. from 5K to red line the sound is evil.
I will try to get some sound clips up ASAP.

Head Installed!!!
Woot!!!
...very nice torque and throttle response improvement that even my mushy butt can feel...Dr. Chad at DT pulled off another successfull installation without a hitch and I left a short time ago...unfortunatly in my haste, I forgot to tighten my plumbings and was only able to see 12psi...
:impatient I need to head back to DT with my SO to pick up my other ride and we'll try another report later...

Hope it's not the boost leak I had recently.
We (Harrison Motorsports here in Atlanta) had taken the front off to install the Exedy flywheel/clutch and a new condenser to replace the one that had been damaged in a small accident.
All the usual boost leak suspects were tested and found to be secure.
Somehow, after all was reinstalled, the little OEM plastic intake hose underneath everything had developed a hairline crack where it had been joined together.
Once we got a new one from MINI, no problems with boost.

Yes.
It's the cheesy little black plastic piece that nobody usually ever sees.
It had separated along its molded seams, but you couldn't really see it.
It apparently took the 10-15 or so lbs. of boost to cause it to leak.

Actually, I didn't describe it very well.
I just checked with Vince (lead mechanic) at Harrison.
It's the little hard plastic duct that comes off the supercharger that connects to the bypass valve.
This piece is made of brittle looking plastic.
The seams are not wondrous to behold, either.

I don't have access to an engine diagram.
I'd suppose that Chad would be familiar with it.
I've heard that this piece is experiencing a few failures. My car (my second MCS) only has 16,000 miles.

To read these...
numbers with circles are fasteners, shown in the lower right of the graphic. If a number points to lots of parts, that's usually an assembly designation.

Are you insinuating your "tuner" (and I use that terms loosely) is the "unmentioned one?"



. I wish I could have seen it in person. I have to live with a few pics
