Did you modify the exhaust when you installed the EVO/GIAC together? Like headers or removing the 2nd cats?

I am not an expert...however, I keep saying the same thing: Porsche has put millions into developing this car...do we really think we are going to improve this car through aerodynamic, engine or suspension changes? My vote is no...in my humble opinion of course!

Hi,
I've said it many times. Mildly Modding a Boxster Engine for performance is mostly a waste of time. The expense is tremendous and the gains (if any) are minimal at best, and usually only on the extreme end of the Tach and usually at the sacrifice of some usable power in the mid-ranges. But, there is a HUGE Marketing Effort by Aftermarket Suppliers to convince you otherwise. Almost ALL gains are Placebic.
Frankly, it's all a lot of Automotive Jewelry. The very best mods without Forced Induction yield maybe a 10% increase (this is really generous, and will still leave your Car feeling anemic compared to many others) and will cost you between $3500 and $5000, not a very good Trade.
There are no quick fixes in the Boxster M96 Engine. Either you go to full Forced Induction (several kits out there, each with it's own drawbacks), or you pursue the time-honored method of increasing the Bore/Stroke, Increase Valve Size and Lift (Headwork, new Valves/Cam), increase Fuel and Air Delivery (intake/injectors), along with a new Box to control it all. I don't know of anyone who's taken this approach because the task is Gargantuan and far exceeds the effort and expense of simply dropping in a 996 Engine.
A much better way to go would be to improve the suspension and put the Car on a Diet, so the stock power has less Mass to push around.
IMHO, anyone dissatisfied with the Boxsters performance simply bought the Wrong Car. Whatever you do to a Boxster, something else out there will Eat it for Lunch. These guys need to step up to a 996/997, Vette, Viper, or the like.
All considered, the Best Induction System for your Car is the one it Already has...
Happy Motoring!... Jim'99

If you really want to move with ALACRITY and DISPATCH...buy a top fuel dragster. Just don't turn any corners. That very point is what everyone is forgetting...you won't beat them in the quarter mile, but you will smoke them like a trout (write that down) in the twisties. TWISTIES PEOPLE...TWISTIES! That is why you bought this car! Say it with me...TWISTIES...Tuh-wih-s-tees.

The boxster is not a ricer and does not respond to modding very well.
I think enough of us have broken our ax on that point, costing us countless dollars and pain.

Which, actually in a way is kind of nice--it keeps us from having to spend money on that sort of thing.

Before I did the Evo kit, I already had the Dansk manifold, sports cat and muffer installed. The works as far as exhaust systems are concerned Dyno tests revealed gains for the manifold and cats but slight loss on the muffler. But I left that on anyway since I kinda like the sound and the torque/bhp loss is not that much...
