To de-snorkel or not to de-snorkel, that is the question.

I think a saw somewhere a post about 5hp gain dyno proven. Not sur if it was here or somewhere else. I need to find it back.

I think I will try it myself and see

Here it is. Finally: Dyno charts of de-snorked 986S!!!

I recently desnorkeled my stock 02 S after 3 months of ownership. I would say there is zero butt dyno difference. However, the sound is definitely more robust. That initial "gulp" of air as the throttle body opens is clearly audible now and overall volume at full throttle is increased. Off throttle and cruise throttle there is no discernible difference.

In hindsight I really should have taken my DB meter and done some tests.

The snorkel mod is a must. It seems like the earlier non-s boxster get more of an audible difference from what I've read. I would not recommend Pedro's hi flow intake mod, it definitely makes the car louder but mine lost a lot of the gargle(for lack of a better word) that it used to have. It just doesn't sound as exotic as it did before with just the snorkel delete.

I desnorkled, removed resonator box from intake and installed NHP Sport 2 muffler. There is a BIG difference in both the sound as well as the performance. This was verified by my shop as well as my driving it over the last few weeks. I installed the muffler over a week and a half ago and am very happy with it.

The growl is nice when the "happy pedal" is depressed more than usual
