OK guys, I'm back from Oxnard, currently the proud owner of the world's only Borla catback exhaust for the 987.2. As I mentioned in previous posts, I volunteered my car (2009 Cayman S PDK) to Borla for fit testing of their new catback exhaust system, and recently the new fabricated unit arrived from manufacturing. Here's the prototype exhaust on the workbench:



And a quick photo of the installed unit, with 4" exhaust tips:



So, I have some good news and some not-so-good news.

Good news: the install was QUICK. Took Borla's mechanics about 30 minutes to remove the stock exhaust and replace it with the Borla. Fit is perfect, and IMO the 4" tips look just right in the rear bumper cutout. I would describe the exhaust note at idle as similar to the low rumble/gurgle you hear from a big American V-8 muscle car, but not too loud. Above 3000RPM, the sound is unbelieveable. I would have to agree with others here that it sounds very similar to a Ferrari engine at high revs. I can also feel the modest power increase the Borla gave, on the order of around +20hp (although I did not dyno my car). Standing starts feel quicker, acceleration from a roll is effortless.

Not so good news: The drone is still there, and it's pretty significant. From about 1800 to 2600RPM there's a very resonant drone that's much more pronounced when the windows are closed and the engine is lugging in this RPM range. I'm still getting used to it, and once I do, it probably won't be as bothersome. I find that running in Sport mode alleviates the problem as the engine will tend to run higher than 2500RPM in all gears.

More not so good news: there's no word out on when exactly this new 987.2 exhaust will be available. Since it's a completely new unit, Borla has to jump through legal as well as marketing hoops before it shows up on the market. In fact, this new exhaust has not even been assigned an inventory number yet. However, I let Chris know that there's a very loyal following of Borla enthusiasts here, and that even some people are waiting on making their aftermarket exhaust decision until Borla shows up to the party. If I were to give my best guess, expect to be able to buy this exhaust sometime early next year, in the first 6 months on 2010 - but don't quote me on it.

Chris @ Borla wants you all to know that Borla's very appreciative of the enthusiasm and support the people here have given their products, and they're going to make every effort to get this exhaust out on the market as quickly as possible, since there's an obvious demand for it. I will also be forwarding him URLs of the various threads here so he can personally respond to any questions or issues about the new exhaust.

Just wanted to express my thanks to Chris Higgins and David Borla for this experience, it was fun - and I'm enjoying this new exhaust so far.

Hope this helps, guys.

Thanks for the update. It's a shame Borla is taking so long to hit the market. Would you say the sound is near identical to the first gen?

That's difficult for me to say. However, the Gen II exhaust is simply a slightly modified Gen I exhaust, so I would guess that the sound signatures are very similar.

Thanks for the info. Interesting design. Does anyone have any audio clips yet of this oon your car? It would be nice to hear.

Thanks for the update.

With the PDK, what is the RPM range for highway cruising at 65-75 MPH in full auto mode?

This is definitely an issue. At 70-75mph in 7th gear, it's smack dab in the middle of the drone range, around 2200RPM. When you're cruising at speed with just a little throttle actuation, the drone is minimal. Under any kind of load, however, brings the drone on full force.

Downshifting to 6th at this speed brings the RPMs up to about 2800, so that fixes the issue.

The fix for any drone is to drive faster or simply put your windows down and enjoy the sound that is Borla :cheers:

The drone is a very personal thing and some (like me) will be fine with it, but there will be others who just cannot get on with it.

Enjoy your Borla Interpol :cheers:

I have not heard the Gen II system, but I imagine it is the same as my Gen I exhaust. Drone is a purely subjective question.

It doesn't bother me at all. I like it, actually. My car sounds like a sports car now. You need to drive/ride in a car with the exhaust and decide for yourself. I waited until after several long trips for work before I was absolutely certain that it didn't bother me at all.

I have said this before, but I see the difference being related to how you use your car. When I grab the keys to my Cayman, I am "going for a drive". Even if that means going to the store, or driving 350 miles for work. Every minute I am engaged and enjoying the driving experience. Some days, you are not in the mood to "drive" and you just want "transportation". I drive my SUV on those days. I can see how the quiet stock exhaust would be preferred if it was your only car and you drove it like it was an E class Mercedes at times. But even then, it just means you have to pick your gears to avoid the drone which only occurs when you accelerate hard from an RPM range that you would otherwise consider perfectly high enough to accelerate from without lugging the engine. It keeps you that much closer to the peak torque range, which I actually like.

I intentionally induced the worst drone the car can produce for a fellow 45 year old professional friend and he looked at me and said, "Cool!"

Find someone who has the exhaust or just take a chance. Life is short. I listened to Gator Bite's Youtube video on headphones and was sold...then I worried about the drone until I drove around for a couple of weeks...then I was puzzled by all of the fuss.

My car performs better and I get 1MPG better mileage on the highway. It give you a more satisfying driving experience even when observing speed limits around town and accelerating at a moderate pace because the sound gives you the sensation that you are going faster than you are. Same kind of thing I liked about my 2.7 Cayman. You would wind through the gears more than in the 3.4, which was fun.

Sorry for the long post...not meant to hijack the Gen II info. Happy Thanksgiving. ;)

Response from Borla

Interpol - I'm glad we were able to work with such a great R&D partner! It was a pleasure on both occasions to have you out to our facility. And most importantly, I'm glad you like your new pipes!

Thanks for the update. It's a shame Borla is taking so long to hit the market. Would you say the sound is near identical to the first gen?

Scottschoe - Thanks for your interest in our product! Along with our various other projects in the works, I'm keeping tabs on the two Cayman exhausts working their way through our release procedure. We will be offering 4" and 3.5" tip versions. While I can't say with any exact certainty when they'll you'll be able to place an order, we are shooting for around the first of the new year. Should we release it sooner, I'll be sure to pass along the update.

With regards to the sound, I would use your verbiage to best describe the differences between our gen I and II exhausts- near identical. Having heard and driven both gen Caymans with our exhaust, I still can't tell the difference. Thanks again for your feedback & let me know if you have any other questions.:D

Re: Response from Borla

As far as drone is concerned I think you will have it to some degree on any exhaust. An exhasut system is made up of compromises.

Re: Response from Borla

Can we see more pics please?

Would love to see how the 4 inch tips look on the car from far.

Kriggans: what gains can we expect out of the DFI engine?

HBFC, as DaveN007 says it is purely subjective, and there are many different opinions on it, and for me the drone is a non-issue as the sound and performance increase overrides it. I drive around the drone and always have done because I mostly drive in the higher end of the rev range

I can imagine it would be difficult to find other modified Caymans in NL to sit in and hear it for yourself. There's a company in Friesland called EPS (Welkom bij E.P.S. - de bekende uitlaatspecialist!) that did some work on my A3 and they made a great custom quad exhaust for my friends S8. If you are happy to not go with mainstream products and get something tuned and made to your requirements (looks wise and sound wise) then these are the guys to go to. They are very well known in tuning circles in Holland and can tweak the sound of the system to suit you and I recommend them.

A different exhaust on the Cayman is the best mod by far IMHO and unleashes the beast within :)

I will try to take more photos in the upcoming days. Currently it's rather cold and rainy in my neck of the woods, and I just returned from a vacation, so expect a slight delay.

Regarding drone: I hope nobody misinterprets my statements above. The more I have driven this car with this exhaust, the more thrilled I am with the upgrade. It's a whole new car. I have absolutely no regrets about getting the Borla installed and I am 100% sure it's going to stay on my car for as long as I own it.

I would describe the drone as a very loud, low-pitched hum. It's definitely caused by resonance in the RPM ranges I mentioned. However, this has become less of an issue the more I drive the car. The benefits definitely outweigh any disadvantages.

I'd be curious to know if drone is a non-issue on Boxsters. I know resonance is amplified by the solid cabin vibrating in harmony with the exhaust, so theoretically it should be much less with the soft top.

Another drone comment:

Over the weekend my wife and I took the Borla...I mean the Cayman...LOL...to "The City" for a dinner with friends. 120 miles each way. Cruising at 70ish MPH. Half way home, she said, "Honey, I love your car but it is kind of bouncy...not as comfortable as my minivan. Love my minivan for long trips."



Not one comment from my very sensitive wife about noise. Even when I accelerated hard. She expects the car to sound aggressive when I hit the gas, of course. I was thinking about the drone and actually downshifted to 5th a couple of times when speeds got below 100 kmh to avoid the drone upon acceleration in 6th gear at that speed. If the sound of the car at cruising speeds for 4 total hours doesn't bother my wife, that says a lot. This is not some 20ish girlfriend, thrilled to be riding in a Porsche. This is my 43 year old (smoking hot) wife who never drove the SL I bought for her because "All of my stuff is in my minivan." LOL.

She has no idea that I changed the exhaust. God, I love my wife. (and my garage) She just doesn't care about certain things and I am OK with that. My 6 year old daughter had to explain once that, yes, Daddy has a dirt bike. He got it when I was 5. It is yellow."

My wife said, "No honey, his ATV is green."

"No Mommy, he has a dirt bike AND an ATV." LOL

Noise, though...THAT would bother her. I was prepared for her being mildly irritated.

Yet another subjective reference, I know.

Borla is in Oxnard?

I ask because I live in Santa Barbara, about 30 minutes from there. I want to have a Borla exhaust put on. Do they happen to do any installations themselves for the general public? Just wondering because it would be fun to see their outfit and maybe save some money on shipping etc?

Unfortunately they don't do general installs. Borla HQ in Oxnard is strictly a R&D facility.

Interpol - Just had all four wisdom teeth out last week so I've been away from the boards for a few days. Thanks for stepping in :D


sicshift - While our Oxnard facility doesn't do installations, I would recommend a great local shop we've partnered with on several past projects: HP AutoWerks in Santa Barbara. Ask for Harold or Peter (get it - HP... he he he). They're friendly fellas & are quite knowledgeable at tuning Porches, BMW's, & Audis.

HP Autowerks Inc [or] 805-966-3200

Thanks for your interest!

Chris, I hope you have fully recovered! My car is stored for the winter now, but I anxiously await the introduction of the Borla exhaust for the 2009 pdk Cayman S!
