does anyone run cats with True duals? I know it almost defeats the purpose, but I dont have emmisions testing but they do require cats...and they will check...and will fail you if you dont have them.

I would really like a tsp setup but is it really worth it if I need to run cats? I am getting flp's so I can run cats when I need to get inspected or get harrased about it. Any suggestions on what I should do??

If you are really concerned, get some little bullet cats, then have 3 bolt flanges welded on the ends, and have the shop make you regular pipes with the same 3 bolt flanges on there, so you can take the cats on and off for emissions, simple as that.

Some have seen 15rwhp gains from removing the cats on modified cars.
