Exhaust system
 

Looking at upgrading my 2015 LTZ Chev Suburban exhaust, want "great sound, mpg improvement and awesome look". should I look at headers all the way through? Lots of different information out there.
Thanks Jono

Put a Flowmaster 40 muffler on mine. Sounds good- not super aggressive. Throaty startup note and noticeable while driving. Drone isn’t awful at highway speed.

What engine do you have? There are several makes of headers avaiable. If you want to go with headers I would recommend ceramic coated ones to keep the underhood temps down, and once you commit to headers, you would have to commit to dual exhaust to get the maximum benefit. However, any improvement in gas mileage will probably not pay for cost of the headers. You might be better off just to stay with a muffler change and perhaps a cold air intake.
