Performance gains Catback exhaust?

[Brichinelo]

I’m heavily leaning towards the mbrp Catback exhaust. I will just get the exhaust for now and will later probably add Jun bl downpipes. For those of you who have the mbrp is there minimal to no change performance wise? Also what is the biggest restriction in the exhaust for the stinger? The q50 rs I had the biggest restriction was the downpipes . You swap those and you already have a good start performance wise . Just trying to get a clear picture of the stinger exhaust in totality. Thanks

MBRP is a fantastic exhaust that is offered at a great price point. You won't see a ton of performance gains from a catback. To really notice a difference in the exhaust you are going to need to change the primary downpipe. The Ultimate Performance Downpipe Combo Kit (CLICK HERE) is going to give you the best bang for your buck in terms of sound and performance.

For what it's worth, my best 0-60 bone stock was 4.2s. After I did a BMS Intake and a Megan Racing catback, I'm consistently hitting 4.0s. No tune or any other mods at all. I only bought the intake and exhaust for sound, had no expectations or intention of any performance increases, but the results don't lie. Before the intake/exhaust and after were taken on the same road and just about the same temps.

Some data to back up your point I like . When I heard the Megan racing Catback it was almost like stock. Looking for a little noise from the exhaust. Those gains though can’t knock that. Have any sound clips of your Megan Catback ?

I’ve heard that kit causing overbooost issues so I’m staying clear of it for now. I’ll most likely just do the Jun bl downpipe for now or just wait until I tune later down the road with Lap3 to add this ultimate performance downpipe kit as the tune should compliment the exhaust as whole and prevent overshoot issues I hope

There's a thread up or down a few posts where I posted a soundclip of it. Here's a link to it. It's a little bit louder in person. If you watched the Megan Racing soundclip of it, it seems ultra quiet in their video because they filmed it with a gopro, which sucks for recording sound. The borla is definitely louder, but is almost 2x the price. The mbrp is probably a little louder than the Megan, but not by a whole lot. Can't go wrong either way though. I chose the Megan over the MBRP because of the price, sounds a little deeper, comes with fresh bolts and gaskets, and I've had good experiences with Megan products before on other cars. Like I said can't go wrong either way though. I also chose the Megan because its a somewhat new exhaust for the Stinger, so not a lot of people have it, so I wanted to be a little different and try that one out. Nothing but good things to say about it so far.

here is a sound bite on mine. Keep in mind the burbles/downshift pop were from my ecu. But it does make slight burbles without it aswell.

Not knocking Megan by any means at all. I was looking for something budget friendly and the mbrp is right there along with Megan as well. I’ll check out the sound clips if I can find them on the forum. I definitely feel you on being different with your stinger. I would like to go that route too and differentiate my stinger from the rest but the exhaust is pretty hard to get the sound your Looking for being the first one to try it you know but I’ll definitely look into the Megan racing Catback some more and see if I find someone in the stinger meetups who has one so I can hear it in person

Can’t go wrong with mbrp imo. I’m still leaning towards the mbrp but

@th3n4m31zd4n has me wanting to hear the Megan racing Catback now especially with no tune and just the exhaust and intakes​

Loving the sound of that Megan Catback. That’s a pretty nice and a smooth good tone with it not raspy. I agree it’s right on par with mbrp. I’m torn now between these two lol. I heard you mention drone around the 2k rpm. Tips will help like you said. This price point is definitely an exhaust you should consider. I wonder if you pair this with some downpipes how louder will it get ? I might take your route and give this a shot to differentiate myself from majority of other stingers. Thanks for the input bro

Gotcha man, whatever you end up going with definitely post up a soundclip or something! If you go the Megan route get it from kdmproject.com... They have it over a $100 cheaper than anyone else. With tax and shipping to your door it'll be right about $700 -+ a few bucks depending on where you live. Also if you go with the MBRP, I'd highly recommend spending a bit more and get the stainless steel version so it doesn't rust quickly. Especially if you plan on getting downpipes eventually too.

Downpipes coming either way. I’m very interested to see what the Megan will see sound like with Jun bl so this might be a good route to go as well . But for sure I’ll post a sound clip whatever I get it

I'm looking for some perspective on this discussion thread as it is recent and mentions both Ultimate Performance and MBRP Pro exhaust. I upgraded the UP Pipes first due to a timing on installation help. The install went great with no CEL, and massive power gains. Big thumbs up there. I just took the next step with installing the MBRP yesterday. The install went great, but it was a shock how it sounds at certain points. Everything is clamped down tight, but it feels like something is not right. In the video, the loud rasp at startup is consistent between 2000 and 3000 RPM just going down the road. Low end on the road is a good rumble and high end has an amazing roar, but that middle note is not a good sound.
Let me know what you all think.

Sorry about the cut up link below, the site says I'm too new to post it straight. Just add an h at the beginning of the link.

I agree bro that startup sound with mbrp and ultimate performance downpipe midpipe combo is not something I want. Not sure what may be the cause but I have heard ppl having overboost issues with the UP downpipe midpipe combo. Hoping someone else can chime in as I also wanted to know some real time info about the UP downpipe midpipe combo.

I called out to MBRP and Ultimate Performance for advice. It appears that aftermarket catback systems are designed for stock downpipes with stock cats. Changing the downpipes and cats are causing the tinny/farting sounds on the aftermarket catback systems. Real bummer, as that means it can only be corrected with a custom exhaust system. That's going to be some $$$$. Super disappointing, so going back to stock catback for now.

I have a megan racing catback that produces no such tinny/farting sounds on its own. it had some drone but aftermarket tips fixed that. It is not super loud though, I would describe it really as an OEM+ exhaust system with a bit of a volume bump normally, but it roars on WOT.

Edit - Im an idiot and did not read what you said correctly the first time. You can pretty much ignore this.

On my q50 rs i paired Megan racing downpipes with an aftermarket exhaust and it was fine so I don’t completely agree with that. I might be missing something though but as far as I know that combo should have worked . How would that sound get corrected if you wanted to go that route ?

How do you like your Megan Catback ? And sound clips ? And do you intend to pair it with a set of downpipes in the near future ? Possibly looking into getting the Megan

I love the sound of it, you will 100% need tips though cuz the drone with factory tips is very noticeable. I have a singular clip of some parked reving with the factory tips on it because its been pretty cold up until the last few weeks and my car is currently in the shop for warranty work.

I also just bought the overkill downpipe/midpipe combo that I eventually plan to install, but I have to get the car back and do some logging for Lozic before I put the pipes on so we can see if he has the tune dialed in before we make any more adjustments. I can link you the clip if you like but it only really shows up to the 5K park rev limiter. a fly by and actually driving the car is much different.

Best description I can find is OEM+ or even OEM++

Are your Megan downpipes both primary and secondary, with HFC on the primaries and cat deletes on the secondaries?

A possible fix might be additional resonators to dampen the sound. MBRP sells them, but then I would have to make cuts. If the sound is still not good afterwards then I can't return them and out the full cost rather than the penalty of a restock fee. Tough call...

There is another thread I found where other Stingers with Ultimate Performance primary and secondary downpipes are having the same sound issues with Borla and other cat systems. I have yet to find a tuned end-to-end system of primaries, secondaries, and catback sold as a single unit. Seems like that route is custom only.
