Deep exhaust/ ZERO hiss

Buzzkill247

From what I have heard out there in order of Rib-and-Skull-Fracture to Dear-God-My-Ears-Are-Bleeding-Still-But-Damn-What-A-Beaut-Of-A-Tone:
Cat/TP - Berk R-TP, ARK Hemholtz HFC, FI R-HFC <<<This is what will net you low rasp and nice tone
Mid Pipe of choice to mate, but H for pop and X for growl/rawr
Tail/Muff - GT Haus Meisterschaft, AAM short tail, ARK GRiP, AAM Res Short, FI TDX, FI 12" TDX, FI 18" Res TDX <<<This is what will net you LOUD WOT but reasonable under DD without drone

IF I am close to thinking what you are thinking, and I think you know what I am thinking you think, but think my thinking may be not what you think .... alright enough of that... I underlined my personal suggestions - certainly not end all tops - but maybe go hit some youtube and see what you can find and at least try to get an idea. Call some manufactures. Maybe download an app for sound measurement and get an idea (best done 6-8ft from source) what dB you want while visiting carshows - use same app to guage sound freq of exhaust you like. then call the manufacturer and talk with them detailing what you are looking for in what tonal ranges and see what they say.
