I was reading in another forum that removing the Exhuast Pipe (some times call expansion chamber or tunner) inproves the WOT performance of these engines. Has anyone done this? |

Aren't you running a sst45 motor? It would already have the correct tuner length in it for your tunnel. What kind of rpm are you turning now? |

The idea regarding removing the tuner cam from some 45ss guys on Scream and Fly http://www.screamandfly.com/showthread. ... -amp-60-HP I re-read the post and it isnt clear. I was just wondering if those who favor "top end" or "mid-range" have tried this. |
