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.
