Tune before or after exhaust?

[Dinner]

Is there much difference if I get my truck tuned before or after I put exhaust on it?

Hopefully getting a local guy to tune my truck soon but don't plan on getting exhaust for awhile, when I do I'm going with a Corsa DB.

Just wondering if in my case where I only have a Airaid MIT that an exhaust will really benefit the truck that much with a tune done before or after the exhaust?

You getting full exhaust? Long tubes, deleted cats? If so doesn't really matter. You can run that stuff without a tune, or get tuned then exhaust and have it retuned. Considering they're free

 

[Jared]

Just do it after to get every bit you can, not that it will be a huge difference...

Ya my plan was just to get it tuned this month.

Cat-back Corsa system is in the works for later this year then after that I won't be doing any performance mods for awhile.

 

[JennaBear]

Exhaust swap provides little to no performance benefit, and there should be no tune changes.

 

[Fiesty]

Only reason for tuning after is if you're doing headers and need to delete the rear o2 sensors for no cats.

 

[Ginger]

Headers do provide much more gain than a cat back system.

Okay, thanks everyone!

no problem, the only part of the stock exhaust that is restrictive is the muffler, everything else is actually pretty good.
