Who has one on their pickup? Just bought a 2004 Silverado 1500 the other day as my new beater vehicle and I am thinking about putting a dual exhaust on it. Was looking at the Flowmaster American Thunder series. What kind do you guys have and how do you like it for power increase, MPG gained, sound, etc. My truck has the 4.8L in it, thats more than enough power for me since I dont have anything to tow. It already has a K&N 57 Series Air Intake kit on it so I figure I might as well add some new pipes

Tony..

a free flow exhaust does add to the mileage but guys with loud mufflers tend to have a heavy foot,so it's a moot point.

If you like a rumble,go for it !!

Tony just go to the muffler shop and put a flowmaster muffler on. No reason to replace the entire system unless you Have money to burn. They need just a rich less back pressure to do alot better.

BTW I'm not a K&N fan. 1,000,000 mile warranty on the filter not your engine if the filter fails.

Well the K&N system came with the truck so I am not gonna mess with that. I was going for the cat back for the added power since I will be going through the woods here and there and driving through the snow. I have been thinking about just the muffler though

Just the muffler will do the same thing for you.

The cheapest way...

hack off the muffler and let her rip..

It'll be loud and obnoxious...

True, but the truck was sold at a price I couldnt pass up. I know its not gonna be huge power gains with the add ons, just looking to squeeze a little extra out so its there if I would ever need it.

Sounds like the muffler bearings are wore out.

I hate when the muffler bearings go. I check those and the turn signal fluid often so I dont have too many problems.
