MRT V2 ... Typical Drone Issue?
I know this is very subjective but I didn't think it's supposed to be this bad, is it?
Went to a reputable muffler shop here in Raleigh today, was actually recommended by another member. Had the MRT installed and I have so much drone that the vibration is rattling my dash. The shop welded the exhaust, I'm not sure what else they could have done or not do? but it's so bad that if I wasn't headed to work I would of had them take it off today! It sounds great on the outside but inside my car is ridiculous. I did buy the MagnaFlow X pipe when I bought the exhaust from Apex but its not magical is it? I wanted to try the exhaust by itself to see if it bothered me before installing the X Pipe but at this point I have serious doubts it will be the answer. Any ideas as to why I'm getting so much vibration? Last edited by RedHotRS; 05-25-2013 at 12:09 AM. |

Res X-pipe will help big time but also kill a lot of your volume. I would recommend to leave if as is for a little while and let them break in. They will settle down a little and you will also get a used to it. If you don't you could always look at doing J pipes to kill the drone

I had a Loudmouth 1 on my V6 Camaro. Much more drone then the MRT considering it doesnt have any mufflers. I for got a Magnaflow x-pipe. My god does that thing help with drone! The only down side is it made the whole exhaust quieter. But not too much. Still, its amazing now. If you want I can give you the part number and a link to my thread about drone.

Really? The X-Pipe IS magical? Lol
Wow, I would of thought something was wrong with my install or the exhaust itself. Never would of imagined it would be this bad. Does it really get that much quieter after break in? If the XPipe makes it that quiet than whats the sense? Is there any performance value to an axle back exhaust? Now I'm wondering how much louder it will be after my CAI is installed? Sorry if these questions seem stupid, obviously I have a lot to learn |

All of our MRT customers absolutely love their exhaust, despite initial concerns. We had a customer call wanting to return after it came out of the shop. We told him about the break-in period and if he was still unhappy in 1 week we would issue a full refund. He called back 3 days later just to praise the system.

I put a sub in my car a week ago and haven't had any issues whatsoever with rattles or vibrations. The sub had kicked ass till today, then it became almost non exsistent at 18-2k. I know it sounds fantastic outside and turned a lot of heads today but the vibrations throughout my car were crazy. Thanks for the optimism |

You should be fine... I put the MRT V2's on about 6 or 7 weeks ago, the first thing I did was to take the car on the freeway and drove it in clean traffic for about an hour. I ran the car between 60-85 mph, all the while I was watching the tachometer and getting bench marks for drone and other in cabin noise. As many have posted here, the first few minutes in the car can be startling anytime a performance mod has been made, CAI's TB's Exhaust, each bring a different perspective and driving experience to the table. There are a few reasons for this, however the most important to note in my opinion is that the car is so quiet from the factory, any cabin noise at all can seem abnormal. This is why you're reading a lot of posts which suggest that you give it some time and you'll get use to the noise level in the cabin. I 100% agree with this advice, in fact while driving in some conditions you'll forget the mod was even put on... until you jump on it a little bit, then your world will be as it should be again... it took me about 2 weeks of listening and watching where the drone kicked in, where I was in the RPM range and as it would start to fade away etc. I've been in engineering and construction for my entire adult life, so how things work is important to me, to be assured that they are working correctly is paramount.
So, having said all of this and I do apologize for the long read... After driving the car for almost two month with the MRT V2's, I really liked the sound, the drone was very minimal however, I do a lot of freeway driving and like my music as well. So for me personally, I decided to have the magnaflow x-pipe resonator put on. I did that just yesterday, May 24th. (Thank you Chase from Apex, for all your help and advice). I really like the results... there is no raspy sound at all, no drone at any speed or RPM range. I really can't tell the difference in sound, if there is any deterioration, I'm being very honest when I say my ears can't pick it up. What I did notice is that the X-Pipe itself brings a noticeable smoothness to the acceleration, not throttle response, the engine is breathing better and the exhaust is balanced out by the x-pipe. For what I was hoping to achieve, it was worth every dime. It cost me about 200 dollars to have both the MRT's and the X-Pipe installed, it took about 2 hours in total. I don't know if that price is good, bad or somewhere in the middle, however the shop that did it is a local ma and pa who have been in business for about 25 years and I prefer to give my money to the small shop owners whenever I can. At the end of the day, it comes down to preference, you'll hear that all over the place and it's true. Just give yourself sometime, magnaflow isn't going away tomorrow, you've got time to decide what is best for you. Good luck! |

Yeah I don't think I'm describing my problems very clearly. I don't have a problem with the "tone" of my exhaust, the tone sounds great!
What I do have a problem with is the vibrations that are rattling my interior. Most people report drone issues only around 70 mph, I have vibration running through my car at all speeds in the 15-2k range. I just drove to work and watched the tach, even at low speeds I got vibrations that ran through my entire car. Does everyone experience this in the beginning? 70 mph is one thing but I don't recall people having rattling dashboards even at slow speeds. Thanks everyone. |
