hello,
i was wondering if you go from a single exhaust with a single o2 sensor, to a true dual would you have to have an o2 sensor on each side? or could you just keep the one

 

This is being talked about right new in this thread. If your truck is stock or near stock I would recommend just going with a 3 inch single exhaust. Thats what I have.

yeah my front end of the exhaust is all stock. with the 2 1/4 pipe going to the single cat. but after that it goes to a 2 1/2 exhaust. hows three inch work out for you? i just like the duals for the sound and looks

 

If you like the look of duals just get a single in dual out muffler. I have a Magnaflow on mine and love how it sounds. Mine goes from the factory Y pipe and has one cat then 3 inch pipe back to the muffler and then dual out the back.

 

thats awsome. now i have a flowmaster super 44 with the single. you have a nice setup. i think that would be a good way to go for me, thanks
