Exhaust systems for 5.3's?

goatguy · August 4, 2003

Can anyone recommend a dual exhaust for the 5.3. I was looking for a exhaust kit that exits from behind each of the real tires. Also one that sound good.

Welcome to the site.

For exhaust check out TBYRNE.

In your post you didn't mention if your truck was a regcab or ext cab or what year it is.

Here are some kits for the 03 but you could chande the year model and do another search! Click here

There are also a lot of members here going with Magnaflow.

I put the American Thunder (exits behind rear wheels) system #17302 from Flowmaster on my 2000 Silverado X-Cab shortbox with the 5.3. I gained 1-2 mpg intown and 3-4 on the highway. The sound is awesome and looks great!!
