20+ Horsepower from exhaust

[Automon]

There is now way your going to get 20hp out of an exhaust on a Boxster, maybe on other cars but not a Boxster. If there is an exhaust out there that will give me 20hp I will buy it tomorrow and sell my GHL system today

Yes you can, i have seen them.

WWW.FVD.DE offer a boxster one with 20bhp gain and many other stores.
This aint a scam. Its well known about the 20+ bhp for a mod boxster exhaust

Anyone interested in a used (5000 miles) GHL system sounds great but it will not give you 20hp. This is the system with the twin 5" cans

But not the zero. Show us some legit dyno scans from a reputable and neutral shop. You will sell many if this is the case. We have all heard and read from many tuners the world over that the oem system is hard to beat. Ruf says 2-3 h.p. with their system. Something seems fishy here. It's hard enough to get 20hp from intake exhaust and ecu (especially without headers and cats).
Show us the proof, we will be happy to review it!

i agree with fletch; there is zero chance of a 15% horsepower gain in a car as finely tuned as a porsche by simply bolting on a muffler. in most cases, without other changes in the intake / fuel maps, you will LOSE horsepower by bolting on a muffler.

for a comparison, FVD's tuning program for a 2.7L includes the following:

tuned headers
DME map
sport air filter

this yields 172kW, or about 230HP. this is an increas of a whopping thirteen horsepower from replacing the headers and reprogramming the whole computer. DME aside, even with upgrading cats, headers, muffler and intake, you'd be lucky to see 17HP in that car.

To get 20+ HP from this car you will need an exhaust, cats, headers, intake and an ECU reprogram. Then you will get close to 30HP more. Just a muffler? Never!

I just got my Dansk muffler and intend to install it over the next few days. My previous before/after showed 6+ bhp gain (at the wheels) from just the sports cat. I hope the muffler will yield about the same.

Look out for my report! I've not forgotten my intake kit. Just didn't have time to do it as the new year meant a lot of late nights for my line of work

all this talk about the 2.7... what, if anything, would this or any other mods do for the 3.2? dont get me wrong, i LOVE the ponies I got, but I always want more.

[Fletcher]

Richard you can expect very similar gains if not more with a 3.2.

Clubhead which cat's did you install? Which headers? Was this on a 2.7, what year do tell all please! I read over on PPBB that the dansk makes some power as well but it is extremely hard to pin anyone down with dyno results against baseline etc. I think we are starting to see some exciting stuff coming for the Boxsters tuning wise and the more choices the better
Every hp counts, my goal is 250. We will see what happens.

Anyone know much about the ignition on these cars? Just about everything can be improved on :dance:

05 is going to be a fun Year!!!!! :dance:
