I've had the CBE for a few months now, it was the first mod I did to my car, and all I can say it I love it. Unless I decide to go single exit at some point I don't think I'll ever be getting rid of this exhaust. GO WITH THE NON RESONATED VERSION! It'll give you a much better sound and I wouldn't call it obnoxious at all, it has a very mature sound to it.
I searched long, hard, and patiently for the perfect exhaust. The stock exhaust was already louder than many stock exhausts out there for a passenger car. I wanted something that was louder but not that much louder. I’m a musician and i wanted something that SOUNDED good. I saw YouTubes of this exhaust and loved that it sounded rumbly. I emailed Corksport and asked all my questions. They responded quickly and were very helpful. I decided to take the $750 plunge. SO GLAD I DID. This exhaust is amazing. Especially with the windows down. Ahhhh it sounds so juicy. Don’t even play the radio anymore. It’s not ridiculously rumbly like a Subaru but still enough. Also, not loud on highway. Actually I hear it almost a little less when cruising. No drone whatsoever, less drone than stock. Surprisingly less annoying when engine braking at city speeds. My MS3 has >100k miles on it but I feel that it’s a new car now :D
This is a great product. I fitted the single exit CBE (which I don't see listed now) a year ago and it still looks like new. The sound is great, especially the occasional pop when changing up under hard acceleration. They even include my car in local autocross videos now where they never used to because the stock system sounds so boring. No problems fitting. Noticeable increase in performance, maybe partly due to the weight saving of the single pipe compared to twin.
Please read in full. I was very iffy in buying this exhaust because I wanted something loud and that would give me great performance. I at first did not think that the Corksport exhaust would do that for me, until I saw the reviews and a buddy told me I wouldn't regret it. So I bought it.... Not only does my turbo spool faster, and gen 2 speed3 have an increase in power, but it sounds sooooo freaking awesome!!!!! I seriously could not stop smiling or hitting the steering wheel out of excitement! I could drive for hours listening to this exhaust, and actually I love it so much that I forgot I had a radio lol. I am not one to give many reviews unless truly deserved but this deserves for than a 5 star rating and it was easy to install with my grandfathers help on a floor jack and 2 jack stands. So if you were iffy like me, all I have to say is don't be!
I got the cat-back with no resonators since in CA, I still need to pass smog I couldn't replace the factory cat. It's certainly much louder than stock, but it seems louder on the inside than out. Had a smile all the way home.
Purchased non resonated and I am more than impressed with the results! The sound is unbelievably amazing! Thanks for another quality upgrade Corksport!
Great exhaust....when I first installed it,the tips were uneven and had exhaust leaks. I contacted Kim and Vincent,they helped me with instructions for adjustments and resolving the leaks. These folks are GRADE A.....Great customer service.... they really care...quality products...Corksport's THE BEST!!
I purchased the version without the rear resonator, it sounds like a dream and my speed definitely seems faster with it installed. I was a little worried about it being too loud but it's just right, it's not too loud when just cruising. The removal and install was easy except for rusty bolts.

Always hesitant when it comes to buying a cat-back. Want something you can hear, but not obnoxious. This cat-back is perfect. Loud enough when you get on it to hear it but quiet and smooth while cruising. Thrilled to have this product on my car.
Just installed today! Great quality and awesome welds on every piece. Highly recommended for anyone looking for a great sounding CBE!!!

How much louder is the exhaust with the resonator deleted? I want a deep crisp sound and with the resonator sounded great. so with it being gone does it make it significanly louder as to bother others? or does it just have a more aggressive sound to it?

I Purchased the Axle Back Section a few years back and it was non-resonated/non-muffled at the time, i currently still have only the OEM Mid-pipe with the resonator in there. I have a suggestion for you guys at corksport, if you welded in a wireless controlled butterfly Valve to the driver side exhaust outlet then this can be marketed as a Valved exhaust system and would also be a great addition to your current lineup adding more robust exhaust system choices. Please let me know if this interests you!

I currently have a racepipe and a resonator delete on my MS3, with my resonator delete does it matter if I get resonated or non resonated? If I get the resonated version can I just take the pipe off and connect it straight to the racepipe with the resonator if I really wanted to?
