i was wondering what getting bigger tips will do to the sound of my truck. The guy at the auto shop said since i have a Y-pipe then its not gunna get any louder. Is this true or will i get louder ?? And i have an 04 f150 5.4 L

 

It will get a little louder, I loved my 4" tips over the 3.5" when I had a si/do flowbastard.

 

Well when I got my truck dualed, the exhaust mechanic wanted me to come out and listen with no tips and a tip on...HUGE difference in tone. Really made the whole point of dualing an exhaust with big tips.

 

right now i got 2.5 inch tips and im gunna have them comin out at 45 degree angles cause they are straight out now i want it to be louder. I wish f150 were as loud as chevys with straight pipe DAMN those are loud lol.

 

If you take off two cats and make it like the 05 and up that only come with 2 then it will be. My truck is just as loud as the chevy's and dodges.

 

I just swapped out my 3" x 18" chrome slash cut tips for the same in 4"x24". Has a deeper tone at idle and a little louder when you get on it. Not enough to really matter.

Is your truck an auto or standard ??? I just listened to your sound clip and it sounds like you chirped second ???

 

takin the cats off is illegal here. i kinda want a meaner look and sound .

 

Its and auto, and your right it chirps second. My mods are superchips tuner, exhaust, and e-fans. Also I am on a 3.55 rear end and running 265/70/17 10ply tires that way 40lbs each on stock wheels.

You might check but i am prett sure you will pass emissions after taking it down to 2 cats.
