I dont know about the power of your cars but this car I am building there aint a show in hell with the Reynard chassis etc unless you put the exhaust down the transmission tunnel inside boiler lagging etc as I attemped with an eight into one design, I gave up and built a complete system stepped headers going into merge side pipe collectors, with stainless 3" inside diameter perforated tube rolled and welded myself plus to get it quiet for round town insert a length of 2" perf tube wrapped in stainless and glass sound deadening, very restrictive but reports that you can get down to 92db with a basic engine so my nascar engine should be under its requirement of 98db to get certified.
Undercar looks better as it shows the nice bodyline etc (I hate sidepipes) but with 675bhp I havent the room to even run a 3" diameter area oval tubes underneath and the worst problem is where to fit large capacity mufflers, sometimes wish I had built a GT40 as you can do anything with them behind the engine.

Took my 460ci powered car to Tubular Automotive in Mass and had racing headers built then sent them Jet Hot for ceramic coating.Stainless Specialties custom built the chambered mufflers,local muffler shop built the rest.Also had to use cable operated clutch to give the headers all the room they need.
