Just a quick off topic question John - you describe your 16V Veloce as a "G90" - what does this mean?

Hi,
What does this system sound like?
Is it the VERY VERY LOUD type or sporty tone like?
All the best

i think ANSA make proper engine heards, with a crossover pipe!! worth getting this if you are changing you exhaust!,
I run 2 1/4 inch off the headers!

Thanks but i have made afew headers in the past and fancy making my own for the ever present budget reasonsI used to use a Piper formula where the length was worked out on cam timing to place peak torque where you wanted it and the dia was to give twice the swept volume of a cylinder within this length. I thought somebody might have the figures and save my poor old brainbox from having to work it out . The 33 would be one of the easiest cars to fabricate on if you have access to a hoist which i have. I believe that reasonable gains can be had with a proper crossover system as the standard setup is more of a freeflow and doesnt use the firing order to extract.

Hi, not good about that,is it because of the 4-wheel drive system is in the way? because mine came off a j-reg series 3 16v,what's the difference apart from the drive chain.sorry about that, thought they where the same |

Guest,
Where did you get the exhaust from.
I'm always looking for a second hand performance backbox, but can never find any.
I've got a nearly new standard system, so I can't justify buying a new one.
