I dont have stock piping but I do have custom piping with a borla xr1 muffler and love it.

+1, also would like to know what size fits best in place of stock muffler

 

for a direct replacement I think either ther magnaflow 18" or 22" works well.

 

I'm running stock pipes up to my Flowmaster 40, then it's dumped after the muffler. Before I dumped it I did have the stock pipes running out the back in stock form, except I cut the stock pipe just after the last hanger. With stock pipes all the way I loved the sound at 2,000 rpm, with it dumped it sounds sweet @ 1500 RPM. I got the Flowmaster off ebay for $45 brand new in the box.

 

what model flowmaster you runnin? got any sound clips/vids?

 

Id say magnaflow 18 or 22 inch

 

Can't go wrong with the Magnaflow 40 series

 

I got the magnaflow 14", and I like that it has a more agressive sound than the 18" or 22". If you swap with a flowmaster, you will sound good, but not really much difference in performance over stock. The magnaflow offers slightly better performance, as it is a flow-through muffler. I paid around $150 installed for my muffler. I think the muffler itself was about $100 brand new. I also welded on a 12" stainless tip and got rid of the gay looking bent stock tip that came on my '05. That made quite a big difference in sound as well. I love the way my truck sounds now!

 

does anyone know for sure which maggy?? 18 or 22? does one have a deeper tone than the other?

 

The bigger the muffler, the quieter it is. 14" is loudest, then 18", and 22" is probably about equal to stock. My 14" magnaflow is plenty deep at low rpm and has an awesome growl when you raunch on it.

 

I just replaced my muffler with a 22inch glass pack.

 

i am planning on doing the 18 inch maggy on my truck after christmas a single 2.5 in and dual 2.25 out and turn it around to be dual in and single out. that should work perfect for an 07 or later titan with stock exhaust

 

I took the banks off last week and put on a 09 stock exhaust and ordered the 18" 2.25 dual in and 3" out part#12278 . The stock pipes brought back the lowend that the banks lost for shure. Magnaflow should be on early next month, got to do some othere dyno related stuff to the truck first.

 

2008.5 with stock pipes. 18" Magnaflow 2.5" dual-in/2.5" dual-out, part #12468. Wife is not too upset.

 

Did you dump it or go over the axle?

 

for sound clips, look through here

i had a single in/dual out fm 40 series with pipes and it was still pretty loud. a lot of drone at 1600-2000 rpms. i wanted a little more performance so i switched to the magnaflow 14" #12226 which is center in/offset out in the oval body. im still running all stock piping with it dumped after muffler. a MAJOR difference in sound. slightly louder then stock at idle, little drone, not annoying around town. but when you go wot, it gets real deep and sounds very good. paid about 80 bucks.

 

I have a flowmaster 50 series delta flow, love it I turn heads everwhere I go. It is deep no rasp and sounds like a monster truck show through the tunnels here in Seattle. I was told by the guy that welded it up that the 40 series is raspy on the titan at high rpm which bummed me out because I have had 40 series on my other rig. But I am so happy now that I went with the delta flow.

 

here is my cherry bomb single chamber single in/dual out...
in a word LOUD... No torque loss (stock Y) - no MPG gain noticed due to tires/lift, etc. Sound clips are in the link that htxtruck posted above.

 

I used to have a FM 40 with 3" piping from the muffler out the back, but a few months ago changed to a Dynomax Bullet "Race Magnum" muffler, dumped before the rear axle. It's the loudest I've heard; very deep, sounds awesome. My only complaint is that at WOT it's a bit poppy. Not a big deal, as I don't floor it everywhere. Got it cheap from Jegs.

 

I swapped the muffler out for a 70 series SUV flowmaster. it sounded good and I used a universal hanger and bolted it up to the cross-member. worked well and no welding.

I have a full stillen now.

I've got an '08 and my fiance surprised me last June with a magnaflow 18" dumped before axle
Its nice but its a little quite for my taste and pretty poppy with WOT.
I think it's a good muffler if you want to be able to hear your exhaust but not have resonance issues in the cab. Definatly not a head turner.
I'm looking for something a little beefier so I can actually hear my exhaust over my AEM air attack system.
My engine is MUCH louder than my exhaust which isn't necessarily a bad thing.
I like the sound of the borla xr1 muffler but I was doing some searching and found that they only carry 1 in 1 out. I need 2 in 1 out. Any ideas?
Took it to a muffler shop and the guy recommended putting an X-pipe before the muffler but I don't see that enhancing the sound all that much..

 

Do you know want number the magnaflow is?

 

I don't want to thread jack but I am also looking for an upgrade from stock. I initially wanted to go with the Banks Monster system, but from what I understand, I will lose the low-end power...which I definitely don't want. I'm looking for something that sounds deep, dual tips, and is a head turner. Possibly the Flowmaster 50 series Delta flow?

Thanks guys:redblob"

 

go for the 40 over the 50. I had the 50, wanted louder, swapped for 40 and I was happy for a while. Flowmaster is not the best performance-wise, though.

 

hey sorry quick question is it better to get the magnaflow 2.25 in 2.5 out or the 2.25 in 3 out? i am curious about the size of the stock tail pipe? i know the stock pipes in are a little under 2.25 in but what is it out?

 

The stock out ends up at 3" by the time dumps. After reading tons of posts and Shailey's dyno testing (Titan likes small pipes), I went with the smaller (2.5") out versus 3" out to help back pressure since I now have two outs. Just my decision. I am happy, but gas mileage is down due to my now heavier foot to hear the rumble...LOL
