Magnaflow is quality, not a $50 ebay CAT.
it remains to be proven either way. correct me if someone has already done dyno tests. sure the gains won't be much, but then again gains from the AEM
alternator pulley around the same price range is not much either, but everything helps, right? or should I say everything adds up.
yes, it could be better than our stock CATs. there are aftermarket exhausts better than our stock exhausts, and making 180 hp at the crank stock in a 1.8 L is pretty darn good.
