[Gekko]

I had a new cat-back, from a major maker, installed last week. On the way home, I could tell this would not do for me. MAJOR drone in the rpms my engine spends 90% of its time.

So now I have around $1100 invested in a system that I can't stand to hear as it is. The installing shop still has my stock system. I feel pressed for time to do something. What?

There's no refund available from the installing dealer or the manufacturer. Do I throw more money at it to try to correct the design deficiencies myself? Do I double my cost by trying another aftermarket system (that may also fail my needs)? Do I put the stock system back on and try to resell the (now used) system that I just had put on?

What would/did you do?

What do you do when something you buy doesn't meet the maker's advertising statements?

P.S. I did listen to videos and read reviews before I bought.

Dude, I've been through about every major catback maker out there. If you don't want drone, go with corsa. It's a unique exhaust note, but no drone. Mbrp, borla, magna flow (what I have now) slp, etc, all drone to a certain extent. Pm me with details if you want more help. I've seriously had 10 different exhaust setups over the past 3 years.

I seriously considered the Corsa, until I heard it, and read the threads by others who still got drone with that one too.

So, what did you do with the first 9 exhaust setups?

There's no drone with corsa. I've had multiple setups on many different cars including the challenger. There is no drone.

Since you have a Predator, Gekko, have you tried disabling the MDS feature and then drive the car?

 

[fhurricane1000]

You can try to use an exhaust wrap.

First, what make did you purchase? That may help the forum decide on a prudent step, and it'll "alert" potential buyers of that same system on what to expect.

Second, if you don't like it, sell it. You'll have to discount a bit, but you'll get most of your money back. Folks are always looking for catbacks and mods, used or not. Heck, I purchased my catback used!

Best of luck and fill in the details and lets see if someone can offer more suggestions.

One option is to re-install your OEM resonators. Their sole purpose is to eliminate drone. They have a straight-through design and should not decrease the effciency of your catback system.

If, for some reason you don't like the OEMs, you can buy good after market resonators. One good choice is the Flowmaster Hushpower II. See:

Major manufacture? Did they claim it was drone free like Corsa does?
Corsa is drone free, who experienced drone with Corsa?

If the manufacture claims no drone you have every right to get your money back and they should honor it. If it's not advertised as drone free, install the Corsa extream and put the exhaust up for sale and try and recoup your money. If its a major manufacture then it should be easy to sell.

To my knowledge Corsa is the only proved drone free exhaust, even the others that claim drone free haven't proved it yet.

I did several searches on exhaust, Corsa was the clear winner in the Drone category. The problem with Corsa was some people didn't like the exhaust note. The extream was a big improvement over the sport series.

I can honestly say the solo exhaust is drone free. That's what they market. That's what I tested. It's very inexpensive and I have not herd one complaint about it. But I have an srt. They put a dozen on cars at cf2 and with no drone issues. They have what they call j pipes that can be adjusted for drone. There customer service is the best and stand behind there product. I would consider selling what you have and get one of there's.

I have too agree, had Solo put on my R/T 6 speed at CF2 and I love it. Great sound and not very loud just cruising. There is no drone on my system at all. For the money you cant beat their exhaust. Great guys to deal with also.

 

[B-Digital]

I have Solo on my RT auto, little bit of drone while MDS is on and cruising at around 2000-2200 rpms, but I just need to adjust the "J" pipes to fix that. I havent had the time to adjust them yet

 

[Mark052]

Gekko, you have a Challenger with an auto tranny so that means the tone (buzzing sound) when MDS engages will drive you nuts when cruising with the majority of aftermarket systems. Which exhaust system do you currently have? Like others have said, there are some workarounds, depending on the system. You may have to sell it to offset the cost of a new system. If it makes you feel any better, the majority of us (me included) have juggled a couple of exhaust systems on our cars (though vtodd may hold the record, LOL) trying to find the right sound.

 

[vtodd]

I would turn the MDS off and then you will eliminate alot the problem with many of the catbacks. What does it save you anways...about 2mpg's or so??

 

[shhnappa]

I too did a lot of research prior to my cat back system as my #1 goal was to get a system that did not have ANY Drone. I finally decided to go with the Solo and must say it is exactly as advertised. No drone at all in all 6 gears. I was looking at Corsa, Borla, Zoomers, you name it, I looked at it. Now, if the system ran you $1100 or so, you can certainly sell it for close to what you paid considering it's relatively new and pick up the Solo for $925, and be out little to no cash and have what you want. Personally, the you can't go wrong with the Solo.

 

[Gekko]

OK, since you asked, the system is a Magnaflow 16513, the Street Series with two mufflers, two 'resonators', and two twin round tips. Note that from their description, it looks like their resonators are forward, and their mufflers are at the back.
MagnaFlow Exhaust Products - For Trucks, Suv's, American Muscle, Diesel, & Sport Compact Vehicles

They've been on over a week now and I can't find any rpm where they don't annoy me. I like the deeper note, but not the rumble and head pounding. Maybe someone else will. Tomorrow the stock system is going back on.

Check the Classified Section for a deal on these.

Thanks everyone for your input. Before I do this again, I'll check into returnability and try harder to check it out on someone else's car.

 

[Skarn]

Wow, that surprises me Gekko. I just put on that same catback in my 2010 SRT8 last week and LOVE it. I only get a slight drone when going slow at around 1800rpms...everything else is sweet! Did you do like the others suggested and disable MDS?? I have the SRT8 auto and don't have MDS...maybe that's the difference.

I'm EXTREMELY suprised to see you having anything beyond very minor drone with that system. I have the same setup except using the stock tips and the only drone, actually more of a blubbering note, is when the MDS kicks in. And it is very, very minor. I keep the MDS off 99% anyway. I will suggest that you put some miles on the system before you chunk it. After a couple thousand miles the sound will improve quite a bit. My only complaint is that I would like it to be a tad louder but maintain the current tone. BTW-Driving in auto-stick will also disable the MDS.

 

[Lashlarue]

My system is stealthy quiet, it has magnaflow mufflers that I have used in the past and were basically drone free .There are too many times when I don't want loud. loud attracts patrol cars.Loud is not fast.I LEFT MY RESONATORS IN PLACE.But with a predator tune my car picked up .6 seconds in the 1/8th. I came within .015 of running dead even against a 392 6 speed.Actually beat the same car when he allowed a friend to drive it.Heating up the F1 tire is a lesson in futility, you side step the clutch at any rpm other than idle and you will spin till the cows come home. If you let up cags will kick in and you will run close to a 12 second 1/8th. Stock Honda Civics will beat you.My R/T is not exceptionally fast, and I am probably a little worse than the average driver.But I win more than I lose. If you positively have to have noise invest in some electric cutouts. You can then drive your car to church on Sunday and not irritate your pastor.

Sorry to hear about your drone issue. Sound is very personal when it comes to volume and tone. Our ears are all sensitive to different frequencies so some thing that appears to have no drone to one person might make anothers molars rattle. I am putting Zoomers on next week so my fingers are crossed for no drone since I've only heard videos. I will post my experience. The cutouts seem interesting too, otherwise I've heard good things about Solo. Exhaust is a big subjective deal so no shame in not getting it right the first time although we all hate to spend the money and time doing something we aren't happy with. Good luck with the swap.
