has anyone done this? ive heard it drops mpgs bad, drops 1 or 2 mpgs, and ive also heard it can even help you gain a few mpgs.

can someone give me some info on whether or not it would drop my mpgs or make me gain some? and would you recommend it?

i have an 07 screw XLT 4.6 v8... thanks

 

You will only lose MPG because you like the loud noise and keep hitting it. That being said, Unless you have a tuner going total straight pipe and removing the cats will set a check engine light. If you are leaving the cats you will still have a muffling effect and it wont sound too bad.

 

i straight piped my 05 lariat i left the cat in and it sounds amazing as for gas millage i really didnt notice a different but like was said before you lay into it alot more so you can hear that rumble it is sexy for sure i recomend it

 

anyone no what straight pipes would sound like with a 302 or 351 (i have the 302 but noing my luck im goin to have to replace a motor after i got it stuck a month ago and would like to put a 351 in it)

 

302 sounds good. i had cat running into y pipe and it sounded pretty good.

 

how much does it usually cost to straight pipe a truck?

 

15 bucks

 

How loud is it? Is it anoying loud?

 

thanks guys, might have to do this til i save up for a good exhaust.

 

got a sound clip of that
