Yes... I am about to get that universal Carsound one put on my 2.25 inch piping Magnaflow muffler system at the local exhaust shop. I have a 1995 EX with AEM CAI, and am about to get a header in the near future. It will help, if you don't race then it probably isn't worth it though. But IMO no performance mods are worth it unless you race... or at least like to go fast.
