Okay i changed my exhaust a little took out 3 small 90 degree bends in the back and made a direct exit. before I was getting about 15 inches of vaccum at idle and full boost was about 21 PSI at 6K in 1st then went to about 19 in 2nd and about 18 in 3rd and same in 4th. since I changed there is no change in vaccum still at 15 but now in 1st it goes to about 19 PSI 2nd 18PSI 3rd and 4th goes to about 17.5 PSI what would cause this??? Nothing else was changed except I replaced the single 3 in inlet 3 inch outlet magnaflow with a single 3 in inlet dual 2 1/2 outlet super 40 flowmaster sounds sssssoooooo much better. I'm gunna see if my friend will video it and then I will post the new look and sound. It sounds just like a V8 low rumble and nice power sound!
