Exhaust upgrade and options

[edevlin]

"I bought a 02 boxster S about 3 months ago, that already came with several upgrades (Carrera S wheels, PSS9 coilsovers, reprogrammed ECU etc).
Right now, I absolutely love the car, performance and looks-wise, and I get a huge grin every time I drive it."

Hi Alex, welcome to the club.... Desnorkeling will add some nice sounds as will a aftermarket intake. The big thing I would try to keep track of with intake/exhaust mods is your ECU tune. Most of the better ECU reprogramming tunes take into account the intake/exhaust situiation. They write software to take into account any modifications to the intake or exhaust, or if the car is stock. If your current chip is for a stock car, be aware that may change the performance of your chip.

I would keep the stock filter and airbox, and de-snorkle. Its a nice bump in intake noise, and avoids any issues you may run into with aftermarket filters or airboxes (there is no power to be had from changing either).

As to the exhaust, you have many options. I have had the GHL, and now have the FabSpeed. Both resonate, though the FabSpeed has less. This resonance refers to the dreaded 2200-2800RPM range where the exhaust noise literally resonates the structure of the car, its somewhat bad top down, but downright obnoxious top up. The conclusion I have come to, is that though I don't want to pay for it, the PSE is the thing to have. If you are looking for the PSE, get the 03-04 version as it is a much cleaner design and looks much better. The PSE sounds great in sport mode, still does not resonate, and can be nice and quick in normal mode.

Now, where I start to wonder....is that since the PSE only has bypass pipes that are switchable via vacuum powered butterflies, why can't one just incorporate these bypass pipes onto a stock exhaust? I've seen the exterior bypass pipes, but I love how Porsche engineered the internal bypass pipes of the 03-04 PSE.

Hmm, I see.. Then I guess, for people like me that can't take TOO MUCH noise from resonance, the PSE is the only option? How much does it cost anyway? Never got to ask, but I figured it would be more expensive than aftermarkets.
Also, is there a switch for normal and sport modes inside the car?

Can someone explain to me what desnorkle is so I can explain it to my mechanic? I live in Greece and he doesn't speak english...

Cheers!

I tried the Gemballa muffler and one of the Dansk Sausage-style mufflers, both of which gave that resonance, which, like for others, drove me nuts. I finally got one of the Dansk Sport mufflers that look like our stock mufflers. It has a higher flow rate (I think I picked up a few ft lbs of torque, but no hp with it), but none of the resonance issues.

I like the sound, but I suspect not everyone would because is has a raspy tone. If you can find the Dansk website they have sound clips of the muffler which do give the character of the sound. Even though it can be raspy when I was behind the car on the last dyno pull I did, its amazing to hear it screem at 7,000 rpm.
