Well hopefully my last question as it pertains to exhaust. I am going to have new exhaust bent up and new mufflers, Magnaflow, installed and have a question about diameter of pipe. Will I see any difference in performance with my 390 going from 2.5" to 3" Is there any significant cost increase. Because if the answer is no then I will just go with 3". As you can see in my signature block a mild 390 never going to be a drag car but I like the lope and want it to sounf a little healthier.
Thanks as always Gurus of the FE world
Also thought I would show you my Moterey
