that's all custom pipe from the turbo back- no clamps, all slip fittings with side-bolt flanges (nothing hanging off the pipe to catch) and the entire thing is bolted to the car, not hung. the thing about hollowing out the cat is you have expanding gasses that are cooling down and losing velocity and then being squeezed back into a smaller pipe, now moving at a slower speed. back-pressure. it's the removal of the muffler and cat that create crackle and that backfiring sound on throttle decel. with the 5th injector firing at wot, when we shift every once in a while you get some flame out the back. thanks, it is a pretty sweet car :)
