The only manufacturer of long tubes for the car is PPE Engineering and Fast Intentions. If you wanted to continue to run a catalytic converter without welding, use the Motordyne Y pipe and HFC option. HFC is from Motordyne as well. The rest of your exhaust would still be Stillen. Whether it's cheaper or more expensive to buy HFC's and get them welded on, idk. I'll break it down so hopefully you get a better understanding.

FACTORY: Headers/catalytic converters/Y pipe/stockexhaust
YOU CURRENTLY: stock Headers/stock catalytic converters/Stillen Y pipe/Stillen exhaust
YOU WANT: Long Tube Headers/HFC/Stillen exhaust

OPTION 1: PPE or F.I. long tube headers (stock cats removed)/ Motordyne Y pipe with High flow cat option/Stillen exhaust
OPTION 2: Same as above but you keep your Stillen Y pipe and weld HFC's on to your existing exhaust.
OPTION 3: Stick with stock headers and buy HFC's from Stillen as you prefer them anyways.

Hope this clears things up
