Magnaflow 12469 resonated x pipe install--home built

[raycer]

Really? I was told the 11368 is nasibasicthe cj pony part murflmu without the piping they add? I already bought it so hopefully it fits otherwise I have to return it for the 12468. I hope replacing the double x pipe with this doesn't ruin the sound.

You could be right. I thought they used 12468. A good exhaust guy will get it to fit tight and high up.

Nice work!

I don't want to piss in your Cheerios, but the 12469 isn't an X, it's a double Y. Which means both pipes run into 1 single 3" pipe then back to 2. It may not make an HP difference but Magnaflow was'nt too keen on the idea for my application.

I only mention this because if anyone else is considering this mod you can get the 12468 which is the 2.5 inch version and a TruX.

so which one has better flow? the 12469 has 3in in and out, yes it does come down to a 3 inch when they cross at one point but is has holes all over the place, so it should breath???... the one you are talking about is 2.5 in and out... when I called the they said the 12469 had better flow that the 12468. I have cooks LT with green flow running in MF 19100 that is the three inch street... I am looking to quiet it down a pit. I am also running a whipple… What do you think I should go with ? I am also looking at the 14419, but I don't think it will do much to kill the noise...

I spoke with Magnaflow on this and they didn't recommend the 12469 for my application(similar to yours). Although others have used it and not had detrimental results. I could'nt wrap my head around necking my 3" exhaust down to 2.5" then back to 3" so I ended up using there bottle style resonators. Like so:

They won't quiet things down as much as the larger suitcase style units but they did the trick for me.

So no videos before and after with these?? :( Would love to hear them.

Your mind is working like mine... why doesn't someone make a true 3 inch suitcase resonator x-pipe…

Exactly! Magaflow does make one but its way to big for our cars

@BigBlue No before videos, these cars are just so hard to get a good recording of with a phone. This is my 4th and final exhaust set up. 3" cat deletes, Magnaflow 3" bullets, and Magnaflow mufflers welded into a MBRP cat back.

Not the best vid but you get the idea. It's tame during normal driving, with a hint of rasp at part throttle, really thunders at WOT. Sounds better in person!

Nice, sounds good!

Very nice!

I had a Magnaflow Resonated X pipe with 2.25” inlet and 2.5” outlet that went into Pypes Street Pro axle backs which are pretty tame touring mufflers. Was happy with sound and volume until I installed LTs. Not bad at idle or light throttle but too much volume when you roll into it for my taste. Just had Stainless Bros 12” straight through resonators added to collectors in place of the pipes that replaced the cats. Now car sounds even deeper with a nice smooth tone and volume is more manageable. Very pleased with results! I need to get a video and post.

Yep, a single 3" is way more restrictive than an X of 2.5" (and is also less cross section than the stock 2.25" catalyst outlet pipes combined). I noticed this when I was looking for resonated X-pipes. It certainly won't help with power, and is why I didn't get the 12469. It may be 3" in/out but there's definitely a bottleneck there now.

Any chance this Resonator would be better? would it fit?

Probably too wide to fit in the tunnel and the spacing between the inlets looks too wide. Not totally sure though.

Good find.... I’ll have to measure mine but that dynomax might work just fine

This is what I find when I look up the
MagnaFlow Performance Mufflers 12469
3inch in and out.
