Ok I got two 2.5 dynomax bullets and tips but I have decided to get convertors two and I havent decided what kind I want for a reasonable price also my local exhaust shop is putting true duals on for 160 buxs is that a reasonable price also where do they move the O2 sensors to on the exhaust that goes in the middle of the old ones. Thanks

 

$160 is very reasonable.

What year is your truck? '97 - '08 I would imagine? Get Magnaflows part #94006 Hi-Flow Cat and have them installed and remove all the old ones. Leave the O2s where they are and make sure the rear O2s are the same distance they are from the new cats.

Enjoy the new sound.

 

O it is a 2005 it only has two cats but the o2 are in the side of the factory cats that why i was wondering where to put them back at
