Has anyone had any experience with Midas " Ravin " performance exhaust? It is supposed to outflow Flowmaster 40 series mufflers by about 30 %. Anything on Midas at all? I am considering them because of the price and convenience. Crazy Horse Racing here in NJ wants $ 1500 to install a Bassini x pipe with cats, parts and labor. Is this too much? They say this includes everything.
