Hi,
This is my first post... I'm working on installing an RB30 engine and 5-speed manual gearbox into a VK Calais (my son's first car project). Can anyone please advise how we should go about modifying/installing the exhaust system?
In particular, where is the best place to locate the catalytic converter, assuming we're going to use a set of extractors in place of the stock cast iron RB30 headers. We're also thinking about a 2.5" inch exhaust system from the cat back.
I know the VL Commodore floor pan on the passenger side was modified to fit the stock cat, so I'm interested in how others may have fitted the cat into the VK... without taking a big hammer to the floor pan.
Example photos would be great, if available.
Thanks in anticipation.
Regards,
Nick
