I have installed today the MBRP exhaust and I have mixed feelings about it. First of all, I can feel some improvements in the performance and the car feels more responsive than before. Second, At WOT I can't really tell how the exhaust sounds because the Arrington CAI on my car is really loud and it is almost all what I hear, though I can tell that the car is louder now somehow. Third, it wasn't a perfect fit and the mechanic had to do some adjustments to make sure that the tips won't touch the plastic piece on the sides of the tips. Also, the mechanic showed me that the pipes are very close to the differential which could be a problem if the the pipes rattle and hit the differential. Lastly, I made the decision to buy this system after I have learned that MBRP added resonators and fixed the drone issue. Unfortunately, after seeing some pics of the MBRP drone free system and comparing it to what I have I can see that there are no resonators on my car. I guess Marylandspeed.com sold me the old system and I kinda feel like I have been fooled. Although I have checked the part number and it matches the part number on MBRP website. I have already paid $150 for installation, will pay the same again for taking in it off and again for the new one. So thats $300 in case I wanted to return it back and get a new one. What I am trying to say here is that there is drone, very loud drone, Its not very big of a deal if that MBRP added some hp to the wheels but I was hoping for a drone free system. I have emailed marylandspeed.com and now waiting to see what they have to say about this issue.

I'd like to thank Marylandspeed for clearing this out for me. I agree It is confusing to tell which system is the drone free even on MBRP's website. I just assumed that since MBRP made the drone free system in july 2010, it replaced the standard one, obviously it was a wrong assumption. Also, I have emailed Marylandspeed a day before my purchase about this issue but I haven't gotten a response so I placed the order and took the risks. I am responsible for that.

The drone is not as bad as some people claimed. I am 26 and I usually crank up the volume to the max so I have no issues with loudness. I'm single and if there will ever be a wife she gotta marry the sound as well lol. As the title says I'm just writing my first impression since I see many people post questions about which exhaust system to buy. I hope that the standard will make up for the drone by adding more horses than the drone free!

@Lonestar: Thanks a lot for supporting me on this, obviously your suggestions are very appealing for me and I'd really love to work something out to get a drone free system with minimal losses for everyone.

@Marylandspeed: Thank you for your offer to help. I'm not sure how much I'll be paying for a discounted system and how much I will be getting out of selling the current exhaust. Though I encourage you to put this peace of information on the product you are selling to help the buyer in making his decision since there are significant differences between the two systems.

I guess I'll drive the car once again tomorrow and see how I feel about the drone. Its a lose situation for me anyway. as I said in the OP, removing and reinstalling a new system would cost me $300 alone! as far as other systems, I was interested in Corsa as a brand, but It was too quite for my taste. MBRP is high quality, great reputation for power increase, and the sound is exactly what the Challenger deserves. Once I read about the new drone free system I made the decision to go MBRP. If I'm taking it off I'm going back stock. I also need to know how much a 10 miles used MBRP worth before I consider any possible deal.

I think I'm starting to like it. I have driven the car for about 80 miles with the MBRPs on and its getting better the more I drive it. I'm really waiting to put my car on the dyne and see how much hp/tq it gained. The car definitely sounds meaner and feels faster than before. Though I got to say the quality of the product isn't that good specially for its $$$. It rattles and the mechanic had a hard time balancing the tips to make them fit in their designated place because the dimensions weren't 100% right on the car (both tips were touching the outer side of the exhaust holes on the rear bumper) I don't think I'll be spending more money on another exhaust. This was the first exhaust system I ever bought and I guess I've learned my lesson when it comes to buying parts online.

bottom line, I'm a big fan of the MBRP exhaust sound, Definitely not a fan of MBRP brand!

Sucks your having trouble with it. I bought my MBRP back in Dec of '08 from BMC(now speedlogix) and the fit&finish was great. Now I have over 45,000miles with them on and they are still holding up very well. We did the install ourselves and it only took about 1 hour to take off the stock exhaust and install the MBRP catback. Not hard at all, I'd suggest doing it yourself if you end up wanting to take it off.

Plus, go under the car yourself and you can easily adjust the MBRP so that its no longer touching the rear valence. I actually just had to do it to mine, got under the car because I heard a rattle(1st time ever) and noticed that one of the claps vibrated over to were it was touching the other pipe. Loosened the clamp and moved it to the oposite side, rattle stopped. But while moving it, I didnt notice that I had effected the rest of the catback doing so. So when I got out from under the car, the passenger side (side of the exhaust I was working on) tip was turned way out of wack. Got back under and adjusted the piping a bit more and voila! Back to being straight an centered.

Good luck, hope all your problems become a thing of the past. Let us know how it does on the dyno!
Thanks Chris, I think the quality of the product is the responsibility of the manufacturer not the retailer. I've read about this issue with MBRP in other threads. I know its not a big problem and can be fixed easily. I'm going to the shop on saturday. hopefully they'll fix it with no more issues.

The dyne is coming mid april, want to put some miles on it with the new exhaust before I go
