T4 into T3 "bursch"/EMW/bugpack exhaust

Tacked this under the car last night, tucks up nice.
(Didn't think to take a pic on the car like a moron)

Why the flexpipe? Is there a hanger for the muffler side?
Looks great tho.

The flexpipe is to hopefully take the ~20 lbs the muffler weighs off the exhaust studs and allow for engine rocking.
There shouldn't be much if any rotation going on: Just as well as the flexpipe can't twist.
Muffler sits just under the rubber crossbar mount supported by a hanger.

I may yet add some support off the motor mounts for the headpipes, but just effectively ditching the large heavy thing at the end of a long lever should help.

Schweet!

You are in the same boat as myself-
Way Overdue for a Build Thread.

So, really, you kinda build the combo around the exhaust.
Esp. when it's an unobtanium combo like T4-T3...

Here, it seems like, due to the diameters of the primaries,
That 42 x 36 would be the limit on valve size?

No sense in putting in anything bigger,
Regardless of other parameters, right?

There's really no point going bigger than 44x38 in almost any case, based on Jakes/HAMs work, and 36 or even 34 may work better for various reasons.

1 1/2" primaries are fine for 99% of applications, and at least the Bursch is a quality piece.
(still not a fan of the EMW pipes QC, but they're workable...)

This setup should work on a bay bus just peachy too :

I'd consider 38s on a 1 1/2" pipe to possibly allow for faster blowdown at initial lift.

OT: I'm still trying to figure out if I can stick the bus tube gas heater over/by the trans... T1 trans went back in today, w/944 axles etc, the Bus trans fit but made the tin a PITA, and the engine/trans sat at an angle.

I should probably concern myself more with getting it running than the heater, its ~100 F here and I'm working outdoors.

Do you need to extend the EMW pipes to use the Sebring style exhaust too? I want to do something like this on my notch.

Probably.
(I only have a couple Bursch systems to check against)

As shown in the pic, the center of the header tucks up closely to the trans in a 914.

It would probably work great with upright cooling, but the Bursch at least will hit the stock fan shroud on a T4.

Adding the "extensions" took about 5 minutes and a sawzall BTW...
