-- exhaust is same as VS, just w/ burnt tips
VS/VSR + stock front pipe: 86.0db
VS/VSR + Fujitsubo front pipe: 85.2db
VS/VSR + Berk catted front pipe: 86.9db
The front pipe was actually better than stock in terms of sound suppression when paired with certain types of aftermarket exhausts.
Next up will be Tomei UEL header and (hopefully) Fujitsubo catted header. Those tests will be done on my car once I get it back from the dealer.
