Re: hog exhaust
my friend has a turbo back on an 03 and it literally sounsd like a jet about to take off! some of the whine is because of the 03 turbo impeller wheel, but it is real loud. i would definitely opt for the the downpipe- they say its the most important part! intake and turbo back were the first 2 things i did to my truck, and it was significantly quicker. the turbo spools up a lot quicker and felt like it spikes higher. my truck ran dead even with my bros 03 f150 supercrew fx4(when i launched in 2wd), which ran between 10.5 and 10.8 at the 1/8 mile track. after intake and exhaust, my truck ran a 10.1 at 65mph thru the 1/8th mile...
