I have a 02 GMC dually and was thinking about removing the cat. Will I notice a power gain for towing my 29ft. toyhauler or is it worth the trouble. Any other mods needed for cat removel?? Thanks

Mabye not a big imporvement, but it will help more than hurt. All you need to do is find a complete down pipe from one that came without. I actually have a spare if you need it:D . | ||
