Well, thanks to a friendly member on this website, I was able to listen to the exhaust on his car before I decided to buy from him. He only had his Mopar performance exhaust, made by Borla, only on for 1k miles. The system looks brand new. He is selling his '09 R/T to get a GWE SRT so he is parting with items he had on his R/T.

Awesome awesome fit and finish. Beautiful construction and brilliantly polished tips. The installation was pop off of his car, pop on to my car. Tips lined up perfectly thanks to seller, who installed the system with great precision.

The sound is very clean, and extremely deep! It doesn't sound too much different from my stock 6spd during start up and idle. Driving around though I noticed more of a deeper, slightly louder tone. What I do love is that there is more of a drone.., yes I said it. I love that drone, especially when you downshift, or the engine winds down coming to a stop. To me that's how a muscle car should be sounding. There is no raspy sounds whatsoever. It has been wife tested and is not obnoxious or too intrusive. WOT the car sounds a lot better than stock. Has more of a clean sounding throatiness too it. Stock exhaust sounds like it has a cold, and is a bit stuffed up. I'm sure I freed up a nice bit of hp.

Overall I am very happy. I got a practically brand new Mopar performance exhaust for under $800, including the installation. Had to jump on that offer. Although I'd like the sound to be louder, I can remedy that with high flow cats and headers down the road.

I would recommend this exhaust for anyone that wants to retain that deep tone that these cars need. Also for anyone who wants to keep things tame, and not bring too much attention from others. It is expensive, but worth it if you can find a deal. I have always loved Borla products, and in my opinion they make some of the best systems out there. :bigthumb:

If you want something VERY loud, to bring attention to yourself, and to let your neighbors know that you are coming home at 2:00am, don't get this system. If you want loud get MBRP, Zoomers, Flowmaster American Thunder, SLP LMs, or Pypes Violators.

Will try to get a clip of it sometime soon.

Hate to be a party pooper but I installed the Mopar/Borla system and could not get the tail-pipes tips to line up to vehicle. The right one lined up pretty good but the left tip pointed about fifteen degrees more to the left...bad alignment
( incorrect bend in or something in left tailpipe)....never even fired it up....called Borla and they sent me 2 replacement tailpipes and new Mopar Tips....same alignment issue...wound up returning the system back to Ma Mopar.

Its ashame as I liked the look and quality of the parts....I still have the 2 extra tailpipes and Mopar Quad Tips.

That sucks that everything did not line up. Maybe you got a bad batch, but if they sent you more and it still didn't fit, I don't know what to say. I've always known Borla to have some of the best quality and fit. What exhaust do you have on now?

Fit was fine for me, and sound is deeper, but more drone. Not a big deal though, I think anytime you get a louder exhaust it will exentuate that drone. Heck, it had drone even OEM.

Thanks! I will definitely put up a sound clip by the end of the week. It really sounds like stock but deeper and louder. I would not classify it as an aggressive system though. People either hate/love drone, and this system has plenty of it. Doesn't bother me or the wife so much. WOT is wicked. :smokin:

I think the quality of the overall system, especially the amazing tips are the best features of the exhaust. It's good to know I picked a quality product, although I do wish it had more of an aggressive tone. I believe on the Borla site they have three different choices for the RT. There's the regular Borla catback, which I believe uses the same mufflers tips and piping as the Mopar catback. This is the most mild exhaust they have for our cars. Then the next step up is the S Type exhaust which is louder, and more aggressive, but still tame enough for everyday driving. Lastly there is the Borla ATAK, which is their most aggressive, loud, in your face exhaust. I think it would of been cool if the Mopar exhaust was the ATAK or Type S., however most car companies would endorse something that does not change the sound too drastically to where it was impractical for the average Joe wanting a Challenger.

I must stress that the standard Mopar/Borla exhaust is still loud enough where people hear you before they see you. :thumbsup:

After Mopar/Borla went back to Ma Mopar I purchased and installed a Flow-master Force II system with the super 44 mufflers and resonators that reuse the factory tips. T
he system fit fine,quality is very good and it sounds awesome. According to the Flow-master tech rep they actually fit these systems and dyno tune them to live vehicles at their (R&D)facility for maximum performance increases. He stated the Borla folks have a well made,quality system however they do not do live (R&D) fit and performance tuning at their facility. So you may get a good sound from Borla but the performance increases may not be as great as Flow-master.

I have the Borla on my R/T and the sound gets better after a few thousand miles, they seem to mellow out with time

Do you really think an R&D will make a huge difference between two exhausts that are the same pipe size? Both Flowmaster and Borla are 2.5" inch, Flowmaster uses chambered mufflers, Borla uses straight through. A catback on a stock car will give 5-10hp at the most. As for the companies Borla themselves claim that their exhaust will add 20hp and 24lbs on a SRT8. I believe MBRP is 24hp!!! Clever marketing on MBRP since a stock 376hp with their uber 24hp exhaust will already give you that magic 400hp number!

I got my catback for the sound, and longevity. If I really want more power from an exhaust I will add more air to the engine and get headers. :thumbsup:

The bottom line was the Mopar/Borla system did not align properly to my Challenger. I am not accepting a $1200 system with crooked tailpipes,you can that's your choice. Yes Borla has straight through mufflers vs Flowmaster chambered(so did the factory systems at the tailpipes)- the bottom line again is the bottom line torque is retained with Flowmaster ,that's where the chambered mufflers give a little back pressure to retain the low end torque...hp may be a we bit up with Borla but low end torque is reduced as they do not R&D the system so their claim for added HP and Torque is BS!

I thought the Mopar cat back was made by Corsa? I've read other posts saying this. Borla? Corsa? Does anyone have proof who makes it?

If you have an SRT8, Mopar is made by Corsa. If you have an R/T, it's made by Borla.

Mopar has now made a deal with Corsa to make a Mopar/Corsa with Corsa's anti-drone system for 5.7s.
I love them and definitely a kick in the backside noticed.
They don't drive the neighbors crazy but will really open up when you're on the throttle. Hardly any drone at all and made in the USA!!
