We have been working with an exhaust specialist who designs and manufacturers systems here in CA for many years. We've had them make the RACEpipe for the Lotus, our new Alfa 4CRpipe and now have handed them our Drakan to develop a track system. Chuck designs each system and has a keen ear for good sounding systems that don't drone. He started back in 1983 so has tremendous experience. Sound is tested on each car and then undesirable frequencies are tuned out. The Alfa system he developed for us is excellent as it kills the annoying drone that exists with the factory 'race' exhaust. Each system is built from T304 Stainless that is either MIG or TIG welded.
I dropped off the Drakan this week so they could develop a track oriented system that would delete the catalytic converters and add a more melodic/sporty sounding muffler. The Drakan is designed to use the eRod LS3 with the factory cats from GM along with a larger off the shelf muffler that is quiet enough to meet sound at Laguna Seca or Lime Rock. This new track system will be louder but we requested a sound that would also be a bit more exotic. The stock LS3 exhaust manifolds will be used to maintain reliability.
I snapped a bunch of random pictures. I was asked not to shoot everything as they produce exhausts for many tuners including some popular German-focused tuners.
