I have and '07 F150 Lariat. I originally added a flowmaster exhasut, but it wasn't near loud enough. So I changed the muffler to a 12" glass pack. (3" in, 2.5" out)
It sounds better, but I'm wanting it louder. I don't know much about exhasut so I'm just asking for suggestions. Thanks.

Iv got an 05 4.6 with y from the cat it's loud when you get on it and when it's cold idle it's mild loud

Is it the 5.4. On my 5.4 I did true dual straight pipes out the back with diagonal tips and it was 200 bucks. All 2.5 inch pipe. It's loud when you hit the gas hard but idles quiet and on the highway it's quiet unless you try to pass somebody. Haha. I just added an x pipe to make it not so raspy.

My Borla sounds great. Nice and juicy when you get on the gas and at idle its pretty throaty

Yeah it's the 5.4. I don't mind the sound I have now, I just want it a little louder.

to go louder you could go straight pipes (cheap) or go true duals with an X-pipe, 2 bullets/magnapacks, and high flow cats (not so cheap)

Just wondering what's so great about an x pipe

With the cats in these truck its not gonna get that loud they are not like the dodges I have had a 8 in glass pack 2.5" I/0 a cherry bomb extreme and a dynomax bullet the bullets and the 8" glass pack sound the best nice idle and screams going down the road but it takes a bit to. Brake in. If it were me I would do 8" glass pack cost effective and sounds good

remove the two rear cats, it'll be alot louder and sound mean as hell. you might throw a code though, its hit or miss
