get a stock turbo set up from the manifold back to start. no fart cans. if you want to experiment a little....... look at the end of he n/a header you'll see that it has 2 smaller pipes at the flange. what would a 1.5 inch staggered(the pipes run side by side)duels W/no cats and 2 small supertrapps do the car. might be cool.....or a waste of time and money but still it'd still look like a stock muffler from the back and the E-note might be pretty wicked too.
