I played around with a lot of ideas to keep the exhaust there.
louvers, to restrictive Remove the tank and route the pipes higher
and have a turndown through valance, looked real stupid no matter
how i cut them so i ended up in front of wheels.
On one Mustang that i built a exhaust system on that had fourlink and steamroller tires
coilovers etc with almost no room for the pipes. I went down from dual 3 inch to four pipes
with same area as 3 inch, dont remember the exact sice now to a "square" box in the place of the
licenceplate with a plate that directed the gasses down. I built the box out of stainless and painted
it black inside so you had to be close up to see inside the box.
But then he had to have the licence plate between tail lights, So i epoxie glued two magnets to
the plate so it was optional
