boxster exhaust too quiet?

[mach schnell]

So my friend drove my 987 the other day and actually stalled it three times, exclaiming, "its so quiet." Now, I have not stalled my little jalopy, but will attest that compared to the 986 S's, Cayman S and 911's I've driven, my 987 is pretty quiet.

I think I choked not having the sport exhaust installed at the dealer at the time of purchase and unfortunately, can't spring for a whole new exhaust right now (although I'd quickly swap out the tips for something S-like). But, anyone know a little trick that can pulled on the stock exhaust to get a bit more bark out it?

Haha...the whole "its too quiet" was used when my dad stalled my car several times when he first drove it. Can you desnorkel a 987? I personally love the quiet approach of German exhuast compared to those tin cans on rice rockets and those American cars that all sound the same.

I agree, look into modifying the intake if possible (desnorkle or switch to high flow). It would probably be more noticable being right behind you anyway. Should make a nice growl for you.

Yeah, this might help turn on your Check Engine Light too!

De-Snorkling wouldn't effect the Check Engine Light, but adding a cone filter might. Just wanted to clarify that De-Snorkling is ok to do.

I am not aware of a Porsche Sport Exhaust option for the 987. Are you sure about this?

I haven't seen any posts on a 987 intake or a CEL problem... I know some of the 986's did have that problem.

[RandallNeighbour]

Too quiet? That's an easy fix.

Just get under it with a drill and a 1/4 inch bit and drill you some holes in your muffler. About a dozen will do real fine.

Then she'll make some noise and you'll know the engine is runnin'.

I prefer the 1/2" bit it really gives the rear bumper that black smoked look!

The only individual that I've read about who desnorkeled his 987 (an S)subsequently resnorkeled when his mpg was dramatically reduced. As 987 owners running 91 in CA will attest, range is not the Boxster's strong suit...not sure I'd personally reduce it further to get more exhaust noise.

I'd agree with bmussatti...from what I know, there is no sport exhaust yet available...sport tips yes, but I don't think that will improve the noise.

Hi,

I seriously doubt that CEL's or lower MPG was caused by desnorkelling. It's only function is to reduce Intake Noise to comply with European Noise Abatement Ordinances.

There's a lot of Urban Myth surrounding this innocuous ABS Tube.

It does not allow Cooler Air to enter the Engine, the difference isn't significant enough to alter the Engine performance.

It does not allow more air to enter the Intake because the Throttle Body controls this, so the DME does not demand more Fuel consumption.

It cannot trigger a CEL because nothing is affected by it's presence or absence except Sound Waves. Removing it may jostle a component or two (especially something as sensitive as a Hot Film MAF) causing them to trigger a CEL, but that's a function of one's removal technique rather than the absence of the Snorkle itself.

All reports to the contrary are TOTALLY Anecdotal, and people are seeing Cause & Effect where there simply is none...

Happy Motoring!... Jim'99

That's why I love my new exhaust.

The "drill into it" suggestion was not too far off the mark. Have a look at my post at

These posts should give you something to think about. I wasn't prepared to spend big $$ on a minor improvement in sound that resulted in no HP increase. Some of the aftermarkets systems are just way too loud. I was also not prepared to bypass the cat, as the boxster is a convirtable and i would have to cop all the ill fumes at traffic lights.

I have drilled my exhaust to bypass internal chambers somewhat. Externally you cant pick any modification to the exhaust. Its louder but not by much. If i want it louder i can just increase the size of the holes.

Im suprised more people have not done this.

I think i'm just going to make an audio recording of the carrera GT at top speed and just play it through a loud speaker affixed to the rear of the car!

Thanks for all the posts and heated debate.

I was certain that the techquipement for the boxster listed a sports exhaust - maybe a brain fart!

[steven]

You are correct.

There is a sports exhaust that operates to bypass chambers in the muffler at certain speeds and rpm (although most will hack it so its always open). There are 2 different types, the earlier (with the bypass pipes being external) and the later one (with most of the bypass plumbing in the muffler)

From what i heave read the porsche sports exhaust is much quieter than the aftermarket sports exhausts (but im sure someone can confirm this). Porsche exhaust, like everything porshe is also more expensive.

mach schnell, yes, Tequipment lists a PSE for the 986, NOT the 987. Interestingly though, the 2006 Order Guide for the 987 did list the PSE in the options section, but it was removed in a printing about 1 month later. I ordered it in my build, and then was told I can't get it. PCNA said the listing in the early printing was a typo.
