Exhaust recomendations for an 01 Boxster S?

Hi everyone. I just purchased a 2001 Boxster S and I would love to hear recomendations on Exhaust systems for it. I'm looking for a throaty sound and a few extra HP would be welcomed.

Jake Raby's dyno says that the standard setup is VERY difficult to top.
But if its sound you want, including the dreaded 3000rpm drone, there's a hundred different views on this site......
Search for Pedro's Garage exhaust mod which is relatively cheap compared to some.

It is true, the stock setup is hard to beat.

I have however changed the headers for some cheap Chinese ebay specials, exceptional for the price. I have also removed the catalysts and put 2" bypass pipes in their place.

More power? Maybe a little. Better sound? It is louder, more throaty and metallic like a Porsche should be, but without the drone like a ricer. This I attribute to the muffler remaining stock.

To be quite honest it was more trouble and cost than it was worth, for little benefit, but it was fun to tinker around with it.

I have headers, no cats and a modified stock muffler and I think it is the best setup for the money. I too would like a bit lower tone at low rpms but not at the cost of a droning exhaust. My current setup sounds stock until you put your foot in it and then it is plenty low and plenty loud.

2001 boxster S exhaust

Hi, I have installed a set of BB headers for a 2.5 with that cat system and a factory S sport mufler and rased fuel pressure about .3 bar. The dyno gain was 12hp peak and 17hp at 7200 . Note, I did have to extend the wires for the O2 sensors . The sound is very good , I enjoy driving my S with this setup.

Is there somewhere we can find this data? I've looked around and haven't been able to find his dyno results.

I doubt he has posted much on the subject

as all it will do is create controversy.

I will admit to talking to him while he was doing these tests ... he was looking for the best combination for a friend's car that would be both road and track. And he was expecting to find a brand he could recommend. His tests disqualified droning exhausts as they had to be driveable. He was surprised at the results of his tests as, of course, they contradicted all the advertising claims.

Your ears only have so many vibrations built into them .....

The dual canister FabSpeed setup (complete with secondary cat bypass pipes) sounds phenomenal with none of the dreaded drone just under 3000RPM.

On a serious note, there is an infinite number of after market cat-back exhausts out there, all of which claim to increase power and improve sound. I think that its fair to say that the prevailing reason why most of us upgrade our exhaust is to improve "sound".
Certain that it is, early on in your research, you will quickly learn that the mere mentioning of the word "sound" in the same context as "exhaust", will incite vigorous debate with regard to the best sounding product. I can tell you from experience, if you choose to upgrade your vehicle's headers and cats, it is no easy task designing a "system" that will result in both improved performance, as well as safety and reliability.
