THought it's time for an update... I removed the turbo silencer tube, I thought it was there to stop the whistle, but I actually noticed that it stopped the blow off sound when throttle is removed suddenly. I removed the intake system as the filter was hanging on with zip ties, the crankcase ventilation tube now goes straight into a 4" silicone pipe and put a pod filter at the other end.
The pod filter is temporary as I aim to run a pipe out the side fender (think NASCAR Brake Duct) then use an in-line filter. If this is dangerously incorrect please let me know. Shy of having a shopping bag fly in, it should be pretty good and cold.
The AC is fixed but not very cold. The guy said the pipes were icing over and its cold, but maybe the engine heat is overcoming it - is there any way to make it cooler, like insulating the pipe?
And looking for a comment on the flowmaster crossover and dump pipe. I can get them both for a reasonable price with delivery. Do they make much difference?
