MBRP fiesta st catback owners!

[TempeST]

I had one planned for this weekend. My pump gas tune is finished so I was going to make one this weekend and post it up. especially now that the muffler/resonators have been on for a while. Ill post the link in the thread when I do.

Awesome, looking forward to it and one last question. When you put the magnaflow where the mbrp muffler was did you have the shop or whoever did it cut the part off that connects to the downpipe from the mbrp and weld it onto the magnaflow?

 

[TempeST]

I had them redo the whole muffler piece. So they put a new flange small mandrel bend and pipe and muffler from the downpipe to the original Murphy section behind the muffler

 

[Koobs]

Cool man appreciate you sharing it. Probably the best exhaust setup I've heard! Cant wait for your video!

 

[TempeST]

Sweet man, I love the subtle rumble it has to it. Really sounds good! Any possibility of you making another vid? Thanks for the reply also!

Sorry, didn't get around to making the video last weekend. weather was pretty crappy. but this weekend looks good to make one.

I just recently installed a depo catless downpipe with this exhaust over the break. It sounds absolutely epic now. Lots of low deep tone rumbles plus you can hear the turbo whistling away now.

I Changed out my MBRP muffler with a MagnaPack and a Vibrant Resonator at the end with a new tip. so its not MBRP much at all except for the Stainless Piping. but heres a video of mine with my DHM EFR kit.

Was this the ultra quiet resonator or the "bottle" resonator?

 

[TempeST]

This was the smallest bottle style12" I wish I would have done the 18" or the bigger bottle style. But I loved the tone of this exhaust

How much drone did it cut down? And how much did it have before?

 

[TempeST]

I Never had it without the vibrant resonator. I replaced the MBRP muffler with a Magnaflow "magnapack" and put the 12" resonator on the exhaust all at the same time. I wish I would have gone with the Large body resonator though because the car was extremely loud with the DHM manifold, EFR, DHM catless downpipe, and that modified exhaust. with both the muffler and resonator on the exhaust it was louder than the MBRP Muffler. but although it was louder there was less drone than with the MBRP exhaust the way it was right out of the box. but my custom one still needed a bigger resonator.

Thanks for the quick response, love the way it car sounds btw. I need to go check the exhaust to see if mine is hitting anything but that drone from 3-4k is rediculous but it sounds soo good. Just trying to see if I need an ultra quiet of the bottle type

That rumble he has is amazing. Most likely from the DHM manifold

i had the same drone. Just put a chambered muffler on and it sounds great. Very deep and not over bearing at all.

Vs this one

I'm gonna assume the second one

 

[PIPLUP]

You were going to originally get an MBRP?

Thanks!! I love the way it sounds. The videos really don't do it justice. It's even deeper in person. Sounds almost like an equal length header subi.

Here is a thought for everyone with alot of drone. Do y'all have a upgraded RMM with stock DP? Mabye the upgraded RMM is causing extra noise to the exhaust because it's connected to the motor mount via that DP bracket?. I may try and unbolt the bracket and just go for a short drive to see if the drone goes away

any update?

Well I ended up adding the vibrant resonator which was the only thing that cut down the drone. Unfortunately I think it more has to do with how I drive and it was too droney for me while in boost. I ended up selling it local. Which is miss the noise and all the pops but at the same time I do love my quiet and only hearing the turbo intake noise while in boost. Even my fiance said it wasn't even loud while in boost so I think it's just preference. Mabye the 3" piping gets too close to the exhaust tunnel and the harmonics then vibrate through the car while under load because the exhaust is pretty quiet outside the car even at wot

I just removed my MBRP Cat-Back, couldn't stand the drone, very obnoxious. I couldn't talk to my daughter in the backseat, I'd almost be yelling and she still couldn't hear me at times.

I've uploaded a video of some in cabin time. The sound uploaded very low so crank it up if you want full effect.
