Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1Original post

Hey Everyone- We've just adopted a 2009 Boxster S from outside of California, and the little bugger came with a pretty bad a$$ Borla catback exhaust . It's pretty big and beefy and a little louder than stock but still fairly civilized. Now here's the rub. On the Borla site , Borla notes that this exhaust is for off-road use only. Since I will in the near future have to get this Boxster smogged and inspected, I expect this will be an issue. So this is what I'm thinking: If you are in the northern half of California and you want to swap your stock exhaust (or otherwise CARB drama-free exhaust), let me know. We could meet a shop somewhere mutually convenient and split the cost of the swap. I'll also buy you a beer/wine/martini while we wait, and Viola! You drive away with an awesome high-flow Borla exhaust with 4" tips, and I drive off with a proper stock (or not) exhaust that will not make the state inspection people take an unduly close look at my new-to-California Boxster. Please let me know if you're interested. Post here or PM me. Cheers!

POST 3Original post

Emissions will most likely NOT be an issue. On 987.2 cars there are no cats in the mufflers, they are in the headers . So, assuming your Boxster still has original headers (and as far as I know Borla does not make headers for our cars, but previous owner may have upgraded them to another manufacturer's cat-less version), you will pass emissions! So enjoy your exhaust

POST 4Original post

I'm in Santa Rosa, about an hour north of the Golden Gate. Thanks for the info on the cats. I'm pretty familiar with the 987.1 and just assumed that the set up for the cats was the same. I called a nearby smog shop, and the guy here told me that as long as the headers and cats are still factory then he doesn't care how loud the cars is, said I could even run without a muffler (going to pass on that idea, though). So my plan is to go get the smog test with the Borla mufflers, and then switch to a stock or close to stock muffler when convenient. I still like the stock sound. I guess I'm getting old. ?

POST 5Original post

Just a follow up. I did indeed pass smog and inspection with the Borla cat back system bolted to factory headers and cats. Cheers and thanks!

POST 6Original post

Just another follow up on the Borla exhaust ... after a nice weekend out (now that our city is no longer on fire #SonomaStrong), I'm not totally in love with the Borla exhaust on our 987.2 Boxster S . It sounds awesome in the upper half of the rev range, I mean seriously a beautiful automotive howl. The low end, however, is okay at best, and it drones at slow cruising speeds. So if you're looking for a great light weight track exhaust and don't too much care about road trips with the wife, let me know. I'm still game for a trade (or maybe a sale) for something a little bit less aggressive. Cheers, Scott

POST 7Original post

I might be interested! Would the 987.2 exhaust bolt up to a 987.1 S? I have an '07 with stock exhaust and I've been thinking about my options.

POST 8Original post

As I understand it, yes, the 987.1 and 987.2 will match up, but, and it's a big but (insert obvious joke here), the .2 exhaust systems do not have the second catalytic in the muffler anymore. Porsche moved the all the cats up into the headers . So while there are externally the same, the are different on the inside. For me, I'd prefer the .2 exhausts just because it feels quite silly to me to run a third set of cats (from both a restriction and weight viewpoint).

POST 9Original post

Never heard or anyone using a .2 catback exhaust on a .1 I know for sure they are manufactured by different companies. You may want to check with Carnewal ( Carnewal - Car parts and accesories ), as these guys are experts when it comes to Cayman exhausts.
