Decided on a new exhaust system while retaining the stock exhaust manifold. The 'double down' cast iron exhaust manifold provides excellent flow without the noise of a header. The early Volvo R team used the same setup on the racing Amazons. Coupled to this is a 2 inch stainless steel pipe to the muffler. The initial muffler used ended up being too noisy ( is there any such thing as too loud? ), so I ended up refitting another muffler with a bit less noise. This allows me to cruise with the over-drive engaged and still be able to hold a conversation with the passenger or listen to music. Overall its a bit more noisy than the stock setup but much better flow and power.
Picture shows the set-up with the rear IPD sway bar. The exhaust tip is also shown with a brushed stainless steel exit.
