I am looking to do a complete upgrade on my exhaust. I am getting ready to order the JBA EVOL with the H-Pipe, also the JBA Headers. Being shorty headers my question is what can I do about the downpipes with the cats. I want to replace those with less restricting ones but I can't seem to find any at all. I may even just decide to get this as well:

It's the last option with the headers, pulley, SCT, and intake, as well as plug wires and throttle body spacer too, i believe.
Could somebody please help me with the cat/downpipe issue though. Thank You!

The Cats are not very restricting on the V6... If you want to remove the cats then go for it... But make sure that you leave the Pre-cats on the car... They will give back pressure, so you dont loose power... Shorty headers will not do much unless you have around 400 HP... TB spacers dont do anything... Pulley will free up HP as long as you dont have a 2000+ watt system... SCT will give about 10 HP or so... I would go to the Local Exhaust shop and have them build you an exhaust... true Dual exhause with flowmasters should run around $450 or so
