IMO they both suck. You spend all that money, and it BARELY sounds better than the stock exhaust.
You can spend the same amount, or less, and get a FAR better sound, and in some cases you can even get a performance boost.
ALL 2-into-2 will drop performance, but it's not a big hit. All 2-into-1 will get you a small gain.
How loud do you want? RPW Slash are shorter than the Victory Swept/SlashNESS pipes, so they are louder. Rippers as well. Conquest Customs Octanes and Ground Pounders are the sickest sounding & loudest. My next Victory build will have Conquest Customs pipes, no doubt.
