Hi Guys
Julian I had a look at my exhaust and your right again just over the back
axle there is a joint that is fairly rusted and other bits here and there.
So today I decided to look at exhausts on the web, well I will never look at
an exhaust again and see a steel pipe that just pumps out smoke.
Its amazing what this metal thing does or does not do in the case of the
stock exhausts. It would seem that to improve the power, torque, fuel you
would have to replace the manifold with a better one and then get a custom
made exhaust of stainless steel in a good grade steel. You would have to
ensure that no crimping of the exhaust happens at any of the bends. Which
means you need to ensure you get an axhaust that has been bent using the
mandrel system so as to ensure the pipe stays the same diameter all the way
even at bends. The way its better to have the correct bore size that having
it too big because this will result in in lose of tempreture along the pipe
and so cause problems in the pulses from the engine manifold. It also seems
important that the muffilers should not restrict the flow. Im sure there are
other things but wow it can be a lot of info especially when you want to
make the cruiser better. I sent off a few e-mails and I will let you know
what happens if anything.
Thanks
