HEY guys i have a borla xr1 3" muffler with a full 3 inch system from header back, with a 14" /3" inlet resonator and a regular size 4-2-1 stainless headers, its on a b18b integra which will be soon a built h22a turbo, if your wondering why 3", i have 2 problem at 2700 rpm and only then it will have a raspy pitch for about 2 seconds, which between first and second is enough to drive me crazy, because "iam that guy right now". next problem is at high way cruising speeds it get extreamly, unbarelably loud, question, what do you guys think i need to get rid of the raspy and loudness, a good high flow cat, test pipe, or really good resonator, or a combo, let me know what you guys think, send me some brand names also, by the way, this muffler has a sick low growl before and after 2700 rpm, not ricey at all..
