yeah..im gonna have to agree with 04kennebellGT, magnaflow does give you that old muscle car tone....and also...take into consideration....an h-pipe will help with that old muscle hollow tone....I wouldnt nessacarily say SLP has that hollow tone...lol...maybe if you wanted a really really pissed off muscle car tone, you could go with SLP..but your best bet would be with magnaflow or flowmaster...flowmasters sound really good with an h-pipe, and have the pipes dumped before the rear axle...sounds really good...hollow...deep!....well let us know what you do.
