Cat-Back System

I was really thinking about getting a Cat- Back System for my 03 Expy, but I looked at the size of my tailpipe, and rethought it. The reason I wanted the Cat-Back was more for a little performance not the extra sound, and if I wanted the better looks, I would just buy a stainless tip for the pipe. I put on a K&N Filtercharger system and did a notice a little performance improvement as well as a little better gas mileage. But mileage is just how you drive your truck, and if it is working properly...we all know that. How many have put on the Cat-Back and noticed a performance change? It's only about $350, but that is money I could put in for new rims, or sound system.

I have a K&N and a Gibson Dual Exhaust, I definitely got more power (and rumble) but expect worse MPG

I would expect a K&N filter and aftermarket exhaust to enhance your gas mileage, not hurt it? Better airflow into your intake and less back pressure in your exhaust system will help your mpg.
