Know this is the forum for lifted and off roading, but curious about an exhaust upgrade. My muffler and part of my pipe are using out so I need to replace soon. I was thinking about a cat-back upgrade, but started wondering if it really would be worth the investment for a lifted Tahoe. Its not like I will be racing this vehicle, but wondering if an upgraded exhaust could help with HP and MPG any. Or if I should save my money and just replace with a regular system.

What have you guys done?
Is it worth doing an exhaust upgrade?

exhaust is more or less for sound, you "can" squeeze a couple pony's out of it with headers and a tune, etc.
but just changing to a catback really won't gain you much of anything other than some nice sound.
some systems might create unwanted "drone"
some of us like it loud, it's a personal choice.
being lifted or not makes no difference............

@gmartin1215 I had a Borla 40085 XR-1 3 inch wide muffler installed in place of my factory muffler. Sounds good, not too loud.

If you want performance gainz I would recommend headers and gut or delete the cats.

x2 on what @Doubeleive stated. Magnaflow, Corsa, Borla, and Gibson are favorites, though there are other brands, as well. There are also some clone knockoffs of these brand name mufflers, that sell at far lower prices and sound the same.

So, go to YouTube and listen to the various muffler sounds, and decide on which one meets your own personal tastes.

Any concern with losing too much back pressure by modifying the exhaust? Say, if I go with headers, cat delete, and a better muffler?

Not that I know of, but others on this Forum who have actually made these mods will chime in.
