Exhaust lenght
 

Is....

A classic downpipe equal in length to a newage downpipe + second cat?

Always wondered if a classic centre pipe + backbox would fit a newage ( ignoring hanger issue )

if your comparing the 'classic' to a Euro spec new-age then NO the parts are different

new-age 2pce d/pipe is longer with a shorter centre section than equivalent classic

if you use turbo back complete they swap

Bugger, thanks anyway.
