2004 Boxster S dyno w/Fabspeed Cat Bypass Pipes - 986 Forum - The Community for Porsche Boxster & Cayman Owners

As you mentioned, the other benefit of the bypass pipes is removing considerable weight off the car. I was surprised at how much those cat/pipes weighed when I pulled them off. The real treat is the mid range sound produced by the bypass pipes...comes in full song at around 3800 rpm.

Yes, at SR. Please let me know what the 3.6 does on the dyno. Also, show them where to pick up the tach signal on yours for the dyno that way I won't have to next time.

None of my runs had the torque line on the print-out.

my attitude is given what these parts cost - if you need a dyno to detect the difference in power - the power gain wasn't worth it. if you like the sound - great. but if you can't FEEL more power - then it's not that much.

can you FEEL the power gain by the seat of your pants butt dyno?

i've modded quite a few cars, and many of htemods I did, produced such small gains that I honestly couldn't feel it - or could only feel it at upper upper high rpms....

on my 2.7L - not sure what kind of gains I'd get by doing cat bypass.... less than 8hp... i'm sure. i would probably wait until the dealer tells me my cats are clogged and I need new ones, then get these and just get rid of them altogether..

I'm very happy for you. Just think how much money you'll save on modifications!

So correct me if Iam wrong all this is only installing mid pipes right?

The mid-pipes did add a little exhaust sound for me, primarily in the 3800 and up rpm's. However, I would not describe it as dramatic. My exhaust didn't really come to life until I added a PSE.

Forgot to mention I have a Pedro (PSE) Sport Exhaust on my car. It's fairly loud when you get into the throttle, but cruises nicely with no resonance.

With all this talk of "cat bypass pipes" I visited the www.fabspeed.com web site. $495 for a pair of pipes? Wouldn't it be more cost effective to have a local muffler shop fabricate a pair for my car? Any draw backs?

ChrisZang · 12-21-2008, 08:20 AM

just picked up a brand-new pair of fabspeed bypass pipes for $230 (incl. shipping) on eBay

Jaxonalden · 12-21-2008, 08:32 AM

Chris,

One time good deal or do they have more? Was it from an individual or company?

I'm also interested in this answer. I have an 03 Boxster S with Fabspeed exhaust. Can I just go to a local muffler shop and have them fabricate a 2" pipe from the primary cat to the exhaust for cheaper?

It is highly unlikely that a muffler shop will fab you those pipes, ask me how I know. Due to Federal laws, they can get a hefty fine for doing so, eliminating any emission controlled part.

And since you are in Cal, you "may" not pass a visual inspection. YMMV
