Re: SL55 Y-Pipe Installed
For anyone considering the addition of a better inlet, I would suggest that you try this no cost test.
I removed the wye pipe and made a short run around the area, came home and cut a check for the needswings inlet. With 'no restriction' without the wye AS A TEST FOR A SHORT TIME you will get the wooly bully feel of what is available by reducing the inlet restriction.
My dyno and 60 times are testament to the better breathing I now have with the needwsings, gasket matching of intake and heads, and the muffler delete. It is an warm air engine and the more air that you can heat the more horsepower youll get. Woody
