Quick snap with the iPhone here at the Exhaust Shop (Carline Seven Hills – can’t recommend enough, Stephen there is a legend – ph 9838 9999/carline.com.au) Finally finished the exhaust with a 3” mandrel rear pipe and straight-through muffler and little dump.
Has a great growl now and doesn’t resonate really at all, so pretty happy with the result.
Going to show how effective a flowing exhaust is, this simple replacement of the stock (collapsing) muffler and rear section has resulted in about 12% reduction in the boost controller’s duty cycle and about a 35-40% reduction in the gain setting (Gizzmo EBCMS II) for the same boost (I aim for around 15.5psi)
