yes I have read almost every thread in this section, I went to a local shop today and he reccomended 2 things, a flowmaster ko series because he is a huge fan of flowmasters... and another one that looks like a glass back but it wasnt hollow like it.

I am wanting to 45 them out the side, what would yall reccomend? I was smooth sounding but sounds really good and loud and doesnt affect my mpg or power

 

No mufflers at all if you are running 4 cats. If you are cutting the back 2 off I'd go with the dynomax bullets.

 

dynomax bullets or magnaflow magnapacks with 2.25" piping

 

okay so your saying no muffler since I have the 4 stock cats?

will that reduce power? screw with my gas mileage?

better yet, how will it sound?

 

no dont do that. it will sound like *** and wont perform as well as with mufflers. Some people and their advice...

 

okay haha, so KEEP all my cats


this guy says he cant do an x pipe because there wont be enough room and im like wtf? he says he does the h pipe thing

also, wouldnt the bullets make it quieter and they are like glass packs?

 

An H pipe will be louder than an X pipe. Both will fit. What year is your truck? Bullets are 1-2 decibels quieter than straights, but sound is muuuuch better on bullets.

 

its an 05 5.4l v8 supercrew cab

 

Well "sound" is a matter of opinion. If yours is like mine, just unbolt the stocker and see just how it sounds, that should give you a better idea. In my opinion it dosen't sound bad at all, nothing like the old school typical "neck" pickup sound. As far as performance goes, it seems that I read about 3 page sticky on exhausts and back pressure.........

 

You haven't explained yourself...


How loud do you want it?





Do you want an exhaust strictly for sound, or are you looking to get ever bit of power you can?

 

You can keep all 4 cats, remove the rear 2, or chop off all 4 and replace with high flows. Bullets or magnapacks on either of those

 

Bullets over straight ANY day!

 

I want a good mix between power and loud, nothin crazy loud like glass packs or straight pipes.

 

I would add true dual bullets or magnapacks, you decide. H pipe for a choppier sound and X pipe for a smooth sound. If you want it louder, you can deal with the cats.

 

Well... If you don't want loud, don't go with magnapacks or bullets...

start youtubing... Find a sound you like


If you don't want to hinder performance, stay away from chambered and turbo mufflers.

Thrush, Flowmaster certain Dynomaxs.. Cherrybombs.....etc..


You want a straight through for unrestricted flow and optimum velocity..


power loss won't be noticable, but it can get to ya mentally....


Borla is probably the best sounding muffler IMO. Deep and sounds good.
