Headers and exhaust

I assume that you have a 4.7l? if so then the only thing that you may want to worry about is opening up your exhaust to much unless you plan on forced induction (turbo/supercharger). Try and find headers with the smallest primairy tubes. if you want good sound for cheap leave the stock y pipe and take off from the muffler back leaving that 20" intermideate pipe. however you you want full exhaust then still get small primary tubes on the headers and say 2.5 ypipe into single 3". this will keep the back pressure to maintain lowend power as well as fuel economy. if you want muffelers try it without first and you may be supprised....other than that don't go with flows they tend to make the 4.7s suck gas like it's noone's business!

ramhammer , we love ya man your always willing to give that advice , no matter what time what day , even off the friends phone , again (besides the point) to be honest headers will not do crap for noise level, and exhaust , if you get the right system , can sound real nice and bad a@@. go with exhaust first , please not the flowmasters , they are quite overated , get something that hammer recommends and for headers , i have the shortys , but if you want more performance get the longtubes. again ask hammer about those.

Thanks ramracing, always nice to hear when you are appreciated.
Now I'd do the Pacesetter Long Tubes in a heartbeat. I have them and researched it quite well. You'd have to spend more than twice as much for anything that dyno's much better, even with my custom ceramic coating done locally, I still paid half what the Dynatechs were and they were the only headers that showed any significant performance over the Pacesetters. Don't cheap out, buy the ceramic coated ones (inside & out) or have it done at a good coating shop.
If you have to or want to keep your cats (I did) it's a little tricky with the LT's, but do-able. As far as exhaust, many with 2wd's do the cutout/dumped deal and like it. But if your thinking muffler, I have the Flowmaster 50HD, which sounds great, especially with CAI & headers, but it doesn't perform well. I'm probably going to a Cherry Bomb Vortex when the FM starts to show signs of wear. The Cherry Bomb Extreme might also be worth a look/listen to you. Glasspack sound out of a muffler, will really **** off the neighbors!
