Straight Pipes?
I am thinking about putting straight pipes on my 99 4.6L. Does anyone have these on their 4.6? If so, does it sound good, or better do you have a sound file i can download. I have some friends with Z71s with straights, and they all sound good. Appreciate any help.

i have a custom exhaust on my truck with noy mufflers. they just cut my muffler off and y'ed off from there. its shouds great. if you are standing at the back of there truck when it is started you can feel the rumble then and while its ideling. i also had a 1997 5.4 L with the same exhaust. i am looking into getting a set of headers and maybe a set of high flow cats. i just hope then it is not to loud. i sometimes set off car alarms at times now. also be sure to get the 20 or 21 inch 3 and a half inch rond tips. be carefula bout what stainless tips you get if you do because they will yellow cause of the heat. if you have any more questions let me know.

re: exhaust
i also have dual exhaust on my truck, what i did was cut out the back cats on each side, i gutted them out, and than welded them back in place, i left the front cats alone, than i have a y pipe, and no mufflers, it is nice and loud, gets a little annoying though going past 70 mph.

For the record, I have no muffler and a single 2 1/2" pipe that exits in front of the passenger tire. It's a lot louder than the dual cat back system I had before, but performance wise I see no change.

when i took my cats off i did the same as Hausladen...cut out the back bigger two and left the front two alone....im sure it does make the check engine light come on but mine were already on...im not too worried about it.....i knew i'd have to put them back on for inspection, so i just clamped those pipes on and left enough room to weld the cats back on inspection time. it does get a little loud around 70 mph, but nothing that a good stereo system cant hide

Well I wasnt gonna get TRUE straight pipes, just no muffler. But I found out my county is part of some smog thing. I'm looking at the Flowmaster 40 Series, the High Performance Street series, not the Delta Flow one, any experinece with these?

what I have heared, by removing the cats in your truck or car you can burn a valve.
Without the back pressure from the cats and the recirculating gasses back into the engine..the engineers at Ford make it difficult in todays trucks to remove the cats, without burnng an aluminum valve.
