stick a cherry bomb in the exhaust tunnel right after the cat and then run piping out the stock location. you get a smooth looking rearend with no muffler hanging down and because of the placement of the muffler resonence does not become a problem.
i used this system on two of my cars and installed another on a prelude. it sounds awesome when you dig into it but at half throttle or less it's not horrible sounding, and not terribly loud.
best thing it you get minimum back pressure at a cost of no more than $75.
ask at the exhaust shop they'd be easily capable of putting it together for you, unless they are monroe or another franchise shop then they want to make money and will over charge you.
