Update tried a DP because I came across a free one and I just had to rebuild it, barely a noticeable improvement, so I went back to the vac sec. I have a front and rear Sidepipe baffles I drilled an 1.5” hole in the rear one and it made a very noticeable in seat of the pants power, the secondary’s are now opening 100% which before they were only about 80% open with the lightest spring, sound did increase a little but I think I am going to drill the front baffle also but I can only get an 1.25” hole saw up there. My pipes are 23 years old and ceramic is starting to rust so I am looking at a set of Gasn pipes, anyone have any input about those pipes?
