here is a chart showing the diference between closed and open exhaust on my truck. all i did was pull the exhaust apart after the y.

not a bad gain but a good cat back would reduce the diference.

Here is a sound clip, starts off closed then about 1/3 the way through I open the cut outs.. https://ls1tech.com/forums/showthrea...ighlight=tr236 I'll post a pre-cam track pass with the open cut outs after the new year. I'm not around my laptop that has the video until then..

Parish, was you graph supposed to show the difference between open/closed? It looks like it was just one pull (HP/TQ) and not an over lay being open and closed.
