Porsche Crest Boxster 97-04 - GHL SS Muffler?

Hi fellow Porsche brethren!

I am just about to purchase and fit a GHL SS Muffler (PEL-BOXRCB) to my '02 2.7L Boxster. Can anyone give me feedback on their experience of this muffler?

>>Is there a marked response improvement ?
>>Is there any HP/LB to be gained ?
>>Does it give a sweeter tone as you power off ?

In addition, are there any other simple (preferably inexpensive) mods to scoop up any HP?

Thank for your time!
Ade

There are no cheap, easy HP fixes for our cars. If you want to go faster in a straight line, get a Vette. If you want to go faster around turns, go to Driving school or attend DE's. Both of these are cheaper than trying to add speed. Either way have fun. Ed

Thanks for thoughts Ed, but my thread was misunderstood.

If you check the gallery for 'Carrera787' you will see I have a 986 Boxster and a 911 Carrera. I am a Porsche club member of substantial track time, in addition to being a pilot (Boeing), so thanks for your suggestion but I am an experienced European bred driver/pilot.

There is indeed no easy HP to be gained from a 986; else Porsche would have provided such. My comment was merely a good-humored examination of any recommended upgrades fellow Boxster owners have made.

Thanks for your time, and please have a great one…

Ps.
Some desire ¼ mile performance of a Vette, but mid engine poise and balance with performance are my goal.

I asked a similar performance question last year, and got blasted as well.

As I recall, I was accused of wanting to participate in the stoplight grand prix.

Welcome to the Boxster forum, don't take it personally, there are many very helpful people here.

I've done two inexpensive mods to my '02 S, which may not have increased HP, but improved drivability and sound. Besides my sport exhaust, I replaced the secondary cats with bypass pipes and removed the stock air box in favor of an Evo Hi-Flow unit. Both provide great sound and quick throttle response over stock. In fact, the hesitation on downshift throttle blips has been mostly eliminated, one thing that bugged me (even with e-gas). Being a track guy yourself, I'm sure you can appreciate this.

As far as "racer" comments and such, don't fret. I do not track my Box S, but have autocrossed it with my son. I made the mods because I wanted the sound and response I'm used to with my track 911. I've been a PCA instructor for years and have driven many P-cars of all shapes and sizes. That's actually how I got hooked on Boxsters, since you could consider me a "911" guy for life.

Set the car up the way you want it and enjoy it. As stated earlier, there's lots of helpful people out there. If you haven't checked before, take some time and look up www.986forum.com and www.renntech.org ...both very active Boxster websites.

JM,
As usual, you are spot-on with regards to your reasoning and 986 upgrades. We must have gone to different high schools together....

To all the fortunate new owners of 986/7 cars; any year, any model; the common wisdom really hasn't changed since my true gearhead days in the mid'60's. Cause the air to move through the engine in the most efficient manner, with regard to necessary backpressure (per cam timing), and intake flow (something to keep the low flying birds out). Porsche has done almost all of this work for you; you just need to clean up a few "appliances" that they had to include to keep others happy (regulatory agencies)....

These are pretty great cars right out of the box. Without spending cubic-dollars, the best you can achieve is: improved throttle response; incredible engine/mechanical sounds, and a steep curve on the Butt-Dyno chart. This will all make you smile. But in most cases, these cars already go way faster than we are able to drive them safely and efficiently, again, right out of the box.... So join your local PCA, and get some DE days in; learning to drive your car as it was engineered, is the best, fastest, and safest (for all of us) upgrade that can be done.... Thus Endeth the Sermon. Have a Great '09, everyone.
Andy
