I have headers, no cats , true duals, with Borla mufflers on my 90. It's a little too loud for me. Does anyone know if Dynomax Super Turbo's would be any quieter? What about Magnaflow?
Yeah, me too.
Here's what I'm thinking of doing: New front Y (no pre-cats), high/free flow main cat, Walker rear Y w/crossover balance tube, and Walker DynoMax mufflers. I want a system with the best flow, least back-presssure, no resonance, with the lowest amount of Decibels that I can get. It appears to be a good idea, but I have no way of comparing the various manufacturers' claims without hard numbers (Decibels @ x ft, cubic feet per minute, back pressure, etc.), and none of the mfrs. offer those numbers.
McSnagg, as a distributor, are you privy to these numbers, or do you know where I could obtain them or product comparison notes? I only want to buy these things once. I am not in the position of "trial-and-error" buying. Know what I mean?
