Thinking about adding exhaust and rims/tires.

Exhaust is currently stock. Thinking about adding a full exhaust system. Is there such a thing as a "performance" catalytic? Would like to run headers to out back, but street legal. Any recommendations appreciated.

How big can I go with tires/rims without a lift? Thinking 33's would be no problem. What about 35's? Again, any recommendations appreciated.

Thanks.

 

Hi sounds like a nice upgrade, i dont know about the exhaust, but i got 270 70 18 toyo MT's which are 33.5's on my stock 2007 4wd

 

For tire, you should be able to put a 285/65/18 or even a 33x12.50 if you have a 4x4.
Good options are BFG all-terrains, Michelin ltx ms/2, Firestone Desti A/T or even Procomp Xtreme all terrains, compare them here: 4Wheel Online Tires
It might rub a little so just add wheel spacer in the front.

 

Thanks for the replies. Big fan of Michelin tires. Had BFGs on my Tundra and they were good also.
