Just redid my exhuast on my 04 z71 ecsb..

old exhaust: dynatech LT headers, hi flow cats into y pipe, single 3 inch to 14 inch magnaflow. outlet dual 2.5 inch to 3 inch tips

new exhaust: dynatech LT headers, hi flow cats, true dual 2.25 inch pipe into x pipe then to 2 dynomax bullets out to 3.5 inch tips.

exhaust is much deeper now and i felt an tremendous gain in power.. mainly low end. im not sure why?.. a tad quieter but not much.. but they say these bullits will break in and get louder

  Installed mine today. Wasn't bad at all, took about 15-20mins or so, had to get up off the ground and get a socket or two so that took some time. But yeah, not bad.

  They are more than decent and about to go out of production I'm hearing as they are in direct competition to some of the other 'names' within the Goodyear brand. They only annoying trait they have is not uncommon to many brands. If let to sit for weeks they take a set and feel out of balance for a few miles until they return to normal. My mega-dollar Pirelli Scorpions did the same thing. Driven every day you never notice. Starfire Solarus HT is what is on the Pickup. Speed rating T. Dizzy is at the shop and I don't remember which is on that one.

  Kenwood Excelon KFC-XP6902C Excelon Series 6"x9" component speaker system designed for select Chevrolet, Dodge, GMC, and Toyota vehicles at Crutchfield This set of Kenwood 6x9 components is just what you need. They come with any and every bracket, speaker and foam needed. They sounded great to me when I used the stock system. After I went all out and added a new head unit, amp they sounded even better. Simple install.
