My genius son Garrett fabricated a really trick and inexpensive exhaust modification for my 2006 FE Coupe. He was able to remove about 24 pounds of weight by eliminating the cross-over pipes that run below and behind the cock-pit. The mod has dropped weight, drastically reduced the cockpit interior temperatures, improved exhaust flow, improved throttle response, and even enhanced the sound to make it more "basso-profundo". With only $65 in parts he elimated the cross-over pipes pictured and got rid of 9 feet of piping and all the angles that the exhaust gases had to travel through to exit. Plus, the stainless tips that he custom fabricated look great matching the polished FE wheels.
