I want let my 5.4L 330 CID motor be heard, but I don't want to wake up my neighbors, or blow my eardrums while driving.
I merely want to replace my stock muffler with something a little more throaty.
What aftermarket muffler is going to be my best bet?

 

Flowmaster Super44

 

That is up to you on what sound you are going for. The best sound from a muffler replacement usually will be a 12" bullet muffler, or a magnaflow magnapack, and sometimes a 14" oval magnaflow.

I have not yet heard a Borla replacement, it has to sound great too!

 

x2.

 

Magnaflow 14" oval body.

 

I have a maggy right now and I like it. It's quiet enough at cruising speeds, but will wake the neighbors if I jump on it. Flowmasters are for the chevy guys; I've never liked the sound of flows on these trucks. I'm putting on true duals with slp shotgun (loudmouth 1) resonators when I finish putting the new motor in. Check out youtube to get an idea of what the different ones may sound like

 

Thanks for all of the replies.

 

magnaflows. flowmasters rob too much power

 

14" oval maggie... good deep rumble once broken in.

 

Flowmaster 40 Series.

As someone that has had both a straight through (MBRP) and currently has a 40 series Flowmaster on the same truck I don't feel that the flowmaster has robbed too much of my power. And I would tell everybody if I did. I honestly feel very little difference. People can argue dynos all they want but all I have to go on is a real world comparison.

 

ive had 2 slp loudmouth 2s and changed them out for 2 40 series...and felt no difference in power...at all... theses trucks are not race cars...they are gonna be slow regardless...ha

 

^ I felt a little more power when put the 40's in the trash and installed some Borlas.

 

thats all i gots to go on is real world comparisons. ive went from flowmasters to straight pipes twice and gained a little torque and top end both times. i dont know much from stock to flowmaster change but i know they aint the best option for performance thats possible. but hey if ya like the sound of em aint nobody cuttin ya down on yer own opinion

 

Nor, did I think that anyone was cutting me down. Mine was only a differing opinion so people can make an informed decision. I'm used to people ripping Flowmaster, . Buttplugs, SlowMaster, etc. I've heard it all on here. It doesn't bother me. Like I said, in my experience the flowmaster hasn't robbed "too much of my power". Is it noticeable? Yes, but barely. And that's what I want any other reader to know. That way they can weigh their own variables and make an educated decision.

 

rllackey28- I listened to your truck, both setups.. both sound great.. which one do you like more on your truck?

I have 14 inch magnaflow now, I really like it, you can hear it of course but Im really thinkin of replacing it with something louder in deepness and aggression. I always hear people knock flowmaster but to me they have the best sound on just about everything, I really like the chambered sound they produce .. trying to figure out what I should try that would be louder than this Maggie maybe a Super44 3inch SI/SO?
