Exhaust System
What we wanted out of this little V-8 was an easy-breathing engine. So it was decided that we needed an equal length dual cat-back exhaust system. The head scratching and many trial fittings began as we tried to figure out how to achieve this in the space available. The only way we could get the system to fit and get proper flow was to lose the trunk well. The trunk well was cut away and a new floor was cut to shape, fitted and welded in.
We decided that it would look really cool to have the exhaust come out through centre of the rear belly pan. Once the design decisions had been made the fabrication of the exhaust began. We used off-the-shelf 2 1/2" mandrel bent tubes to snake our way through, under, between to get the pipes out the back end. From the header to the Aston Martin tips we used 2 1/2" pipe welded to Mandrel bent tubes.
To fit the exhaust from the front side of the engine we enlarged the stock notch in the engine cradle and reinforced the enlarged opening. This would allow us to have both pipes going through the same notch as seen in the pictures.
We routed the front pipe down and under the front of the oil pan, one of the cats was mounted here and then run through the modified cradle and into the Dynamax dual in, dual out muffler. The backside exhaust swung down and ran through the same enlarged reinforce notch in the cradle, then turned upward and the second cat was put in place above the muffler and then run into the muffler.
We came up with something the Ferrari guys might think came from one of theirs.
