Magnaflow Resonated X Pipe

13M5F10 · 11-22-2015, 11:50 AM

I recently installed Catless Downpipes that was coupled with the Turner Muffler Delete and stock resonators and I found the car had this very high pitched raspiness to it. The cabin drone was too loud and not tolerable for passengers so I went on a mission to find an exhaust system to replace my turner with but before doing that, I had this suspicion that my stock resonators may be the culprit to the high pitched raspiness so I decided to fit on a Magnaflow resonated X pipe and I am amazed. I got the idea from my ZL1 that when had aftermarket headers added, it was extremely loud and the MF R X pipe made a huge difference.

I will follow up with more videos but here are some comparisons.

In cabin noise is practically gone unless WOT and it's still very quiet and the noise is behind you rather than inside the cabin resonating. It sounds so much quieter than stock while cruising yet outside the car still sounds beastly. There is practically no drone compare do before. The noise now is much more deeper and refined compared to any other system I've heard. Hard to explain.

PN Magnaflow 11386 Stainless Steel 2.5" Oval Muffler - Fabrication had to be done to go 3" OEM piping to 2.5" and back out or use a 2.5 to 3" adapter. So far no performance issues.

MCarsFan drove my car yesterday and fell in love.

Another run I did. I need some rev and WOT.

Sounds good

13M5F10 · 11-22-2015, 12:36 PM

Cold starts are still loud but no longer high pitched. Just a deep rumble

Off topic but , Is your License Plate referring to your previous car (AMG?) or you are humiliating AMG drivers? LOL

Was that an amber euro turn signal I saw?

No, must be the camera. US spec here. I do always wonder why they don't do Amber here.

looks like you solved raspy exhaust problem.
Nice videos!

That and best part is no interior noise/drone while cruising and it's awesome when WOT. It's interesting since WOT the exhaust is pretty loud outside yet inside its comfortable.

Thunder43 · 11-22-2015, 07:08 PM

Sounds like you have it dialed in. Well done. Now if we could just code out that cold start!

Great job sounds perfect! Tune will get rid of the cold starts

Can you post where you bought it or model number? I am thinking about doing this

I'd love to do the same.
To get rid of the raspy sound. My cold start is gone (Thank god) tuned out!

Only draw back is I'll ruin my LXR mid-pipe for resell Value.
But I rather fix the sound and make it perfect as possible.

BTW I don't hear your waste gate rattle

You can probably sell that LXR but I agree wont be the same value as purchased.

I added the P/N to the first post.

As for waste gate rattle, it is definitely still there but I agree it isn't as loud as it used to be. Used to be very loud since I have intakes, catless DP, and straight pipes.

Awesome, Probably quieter because the donut gasket broke in more.

I noticed mine gets quieter every week.

Car sounds great, good work. I have actually had this same thought in my head for some time. The only difference is that I was thinking that a 3 X 3 Resonator would work better. I have the same thing in a larger Magnaflow setup. Now I am going to get under there and see if it works. Thanks.

Look at the size of the Resonated X pipe to compare with. It was a perfect fit.

The stock resonators are an issue and I recommend anyone doing muffler deletes or exhaust system to change them out to an aftermarket setup or delete. It has a high pitched raspiness to it.

bm5bullit · 11-24-2015, 02:48 PM

If is not too much and you haven't thrown away the stock resonators; what does the baffle inside look like? Any way you can take a pic of the inside? Thanks.

I never kept them. It was hollow of course and the inner walls had 1/2"-1" holes everywhere.

Interested in doing this myself. How does this effect back pressure? Loss of perfromace?
