This build is badass. Keep it coming.

for the proper exotic high pitched sound the exhaust converging air collector box should be equal to as close as 1.25x the total engine displacement as possible. this is how kreissieg does it and they make some of the highest pitched exotic sounding exhausts that i know of. cant find the source but i specifically remember the 1.25x specification. just my 2 cents. Also to simulate free air high pitched exhaust it helps to have the collector box as close to the engine as possible (but no less than about 50-80cm) and you get the best tone. here is an v8 with a kreissieg.

I really appreciate that information, because I have been trying to do some research into this, and there really isn't that many details or formula's available. I was going to leave the top of the box temporarily tack together to experiment with some baffling or dividing the box to see if there were any changes, but I was going to start off with both mufflers entering in opposite side of the box against each other, and see where I go from there..

This whole build has moved forward with by assumptions things were going to fit whether I an custom make it or alter it, and so far it has all really come together fairly smoothly with these being some of the last details to sort out..

Working on the muffler mock up until the Black Widow shorties make it in, so I figured if I made the longer Flowmasters fit in place, I will have more than enough clearance. The overall plan is to have both the Black Widow shorties mounted like it is pictured here, but then they will dump into a collector box between them, and it is this collector box that will have a cut out to exit at the back body panel. I am hoping this will change the over all exhaust tone to something a bit more exotic, along with taking the LS corvette sound out of it, because I want this car to sound unique. It is also being done this way because we don't want exhaust tips coming out of the body, and we are very tight for space if we want ground clearance by not mounting the muffler under the frame.

To help with heat and to separate the exhaust and fuel tank, I will be building a thick structural floor above the mufflers and also cutting away the bottom body work below then to give the mufflers plenty of air space and fresh air. The factory fuel tank was mounted where the mufflers are now, so it will really just be raised to a higher location, and it appears it may be better to relocate the fuel fill to the top center of the rear body work.

To help with the rear wing support, the rear of the body will be built like a boat transom and the whole rear will be beefed up, along with the inner side panels that it ties into it, plus there will be other brace supports that tie all of this into the chassis to.

wow... this is killer.

reminds me of a current sls amg gt3 combined with the old 300sl gullwing body lines and fenders

this thing is BOSS

ps. keep the round ford cortina tail lights. the square back models look so sad and droopy in the rear

Put the body back on the chassis for a what seems to be the hundredth time so far, but it comes off easy enough when needed, so it is best to be safe than sorry with fitment testing after each step. I am working out the rear muffler/fuel tank situation that has to all fit in the rear body work for space and design issues, and after this I am about home free with all the questionable have too's involved with this oddball project.

As you should be able to see in on of the rear view pics, I have great ground clearance overall by running the exhaust work through the chassis as much as I can, so that is why it is important for the Black Widow mufflers to be mounted transversely up inside the rear body work with a center exit exhaust coming out of the body work somewhere about the black painted area of the rear

The whole build and those body lines after widening....

Hell Yeah subbed for sure!
