Exhaust Replacement
After installing a new industrial VP, my mpg was 21.6. Just installed the XZT+ and have it set to 35hp (fuel econ mode), response is good. Will follow-up in a few days regarding the mpg and performance.
What would a 4in exhaust do for my engine? I tow very little and I try (emphasis on try) to drive conservatively. Exhaust temps are from 600-700 (normal traffic) to low 900s on acceleration and climbing. From what I have read, larger exhaust will lower my exhaust temps, Question do I need to lower the exhaust temps given the above info?
What will I gain from swapping to 4in? Will there be a difference in performance? The reason I’m asking is that I have red threads that described very little increase in performance.

Which single exhaust do you recommended?

4 inch will sound bettdr EGT's and give a litlle gain in power maybe. I would reccomend a cheap one. I couldnt justify spending twice as much on an SS system when they really dont put out any condensation to rot it out.
Mine are about the same but I would like to be lower. It doesnt look like you are putting too much fuel to it so i guess you are fine there. I went aluminized. You can get a good aluminzed fit for around $275 or less if you shop around.

I runthe crap out of mine so I am not sure on Milage but i get descent miles still. It sounds awesome but I am getting ready to go to 5 inch. 5 inch sounds AWESOME. On a mosstly stock truck i would say 4" is your best bet.
