Aftermarket Exhaust / Mufflers
 

Did a search but surprisingly very little info posted. Who is using what and how does it sound? I'm looking for something a little louder but not over the top. I have to run my cats in my county, so removing them is not an option. I have heard that the Active brand by Vivid isn't quite loud enough. I have seen Beluga and Circuit Werks ads but have no sound clips.. Anyone shed some light?

I have this:

Perfect for the street. Sounds awesome, but not annoying on a cross-country trip.

You might want to to tell us what year and engine you have.

The real challenge is weight reduction.It is a massive weight at the wrong end of the car. Check the Racing Forum for ideas ?

Well.......
 

.....the issue with the 986/987 Boxster muffler is that it is a "tuned" part of the engine balance system. The muffler was "tuned" by the engineers to absorb vibration and harmonics in the powertrain. It acts as a vibration damper.

Soooooo, if you install a super light muffler, you will get wicked annoying drones and other vibrations in the cabin.

If you are just driving her like a regular car, out in the "Real World", then you will want to keep it as OEM as possible. That's where the FVD Brombacher "Sound Version" muffler I posted works. Great sound, zero down side.

Now, if you are racing this thing, then sure, you can drop a lot of dead weight and put on some super light muffler. But that will drive you batty off the track.

There's no real point in installing a super light muffler, unless you've stripped the interior, all the carpeting, and gone on a diet yourself.

Good luck.

I understand and weight loss is not really the plan, it's more about sound. I did the fister mod on my 996 and its about perfect, so something similar.. It's a '97 2.5. I just picked it up for REALLY cheap and I dont drive it much and certainly not on any long drives, I just basically scoot around town and will do some AX. A friend of mine went with the Active and he said it was way too quiet and I dont really want to spend as much as the one you posted.. I assume the Circuit Wekrs and Beluga are too loud and might cause the issues you mentioned?

I installed a Top Speed for better sounds and it sounds great!! Very similar if not identical to the Manzo and other made in china systems. We removed the 2nd set of cats too which are really only needed in California.

Shop Around for the best prices:

I have the Top Speed on my 97 2.5 along with their sport headers. Lots and LOTS of cabin resonance between 2-3k rpm. It's deafening when I must raise the top and windows to poke along in traffic (in the rain or sweltering Houston heat and humidity).

If it were not for the outrageous heat buildup in the trunk and the weight, I'd put the factory muffler back on. And I just might anyway. I've taken my car from stock to a full race suspension and exhaust and now almost back to stock. The Porsche engineers really knew what they were doing when they designed the Boxster.

Based on some of the feedback I read here, I put a beluga muffler (same as top speed, manzo, circuit werks, agency power etc) on my 04 S in the summer. I took it off the same day. It sounded great at high rpms but the drone around 3k was unbearable, to the point where it gave me a headache after 10-15 minutes. Mind you, I already had secondary cat deletes installed before I put the muffler on so your experience may vary. I currently have the cat deletes installed with the stock muffler and while I wouldn't mind if it was a bit louder, I'm alot happier than I was with the beluga. If I were to purchase a muffler now I would heavily lean towards something that provides a bit more sound but still retains the factory single chamber design (FVD, Dansk etc).

I like the idea of the bypass pipes. If you need the car to quiet down for a bit, you can stick in transom plugs and you're back to stock in a minute or two. When you want it louder, pop the plugs back out.
PSE would be nice, but cost and availability are prohibitive.

I like my Dansk sports exhaust a lot. No drone.

Hmmm, bypass pipes would be nice. Great idea. Keeping all the tuned portions on and just adding a small escape route. That's basically the same thing the 993/996/997, etc. fister mod is and I love it on my 911. To me its the perfect sound. I have no idea why i didnt think to try that on this car. lol.. And its SUPER cheap! (As in like $20.00!)

This is how it looks on those cars. Basically same thing.

OEM PSE (Porsche Sports Exhaust) are IMHO not loud enough. They look great and are OEM... but. I went from an OEM muffler modified by FDM FD Motorsports » Fister Exhaust – Boxster to the PSE. The FDM had a better note. I deleted my secondary cats to give it some additional sound.

So you liked the Fister sound over the PSE? What did you do with your old setup?? lol..

Liked the sound of the Fister and the looks of the PSE. Sold the Fister.

I would like to hear the results of this mod. It should give the flow and sound of a straight through but without drone and look stock.

Sport Exhaust
 

I have seen some cut away views of the stock exhaust but haven't seen one of the PSE. Has anyone opened up the muffler? I want to go a bit louder but cannot afford 2k plus on a good muffler and don't want the drone from the cheaper stuff.

Why would anyone cut open a factory PSE muffler? It already has the bypass valves, and you can basically see where the bypass pipes feed from the outside of the muffler. :) My Dansk exhaust sounds better than stock, there's no drone whatsoever that I can detect, and it's not anywhere near $2000. If I recall correctly, I got mine for $750. Or, you can have a muffler shop fabricate a PSE with 2 pipes, and it won't drone either (for much less money than a new exhaust).

I have the "Pedro Sport Exhaust" on my '98, and it sounds very nice, but it's a bit louder than I would like, particularly on longer drives. I'm considering putting the OEM muffler back on the car, but do like the "growl" the PSE exhaust provides.

It is way too quiet for me. That is why, unless someone nearby would like to trade.

What is way too quiet for you? Which exhaust do you have? What model year is yours?

I have an 02 S with the PSE. I hear more out of the intake vent than I do from the exhaust. I would also like to hear more "burble" at idle.

Bypass pipes fitted to mine. Cost me £130 all in.

Same camera (iPhone 6S), same distance, same car. Sounds perfect. No need to spend hundreds when this gives the sound of the original PSE :) you just don't get a switch, but why would you want to turn this off ;)

The after sounds great!

Maybe you can have your valves clamped to stay in the bypass position at all times, and also install cat bypass pipes? I have listened to a fellow Boxster owner's PSE with cat bypass pipes, and it sounded pretty good.

I was thinking that same thing, they had a pair of bypass pipes on Ebay for $200, then they went up to $1200. WTF? Anyway, I may see about having a local exhaust shop make some up.

Someone here sells muffler bypass pipes for $100.

Holy!!!! $500 for a couple of pipes with flanges?

If they fit on a Porsche, they're special pipes! ;)

Bypass pipes is one of the few things that you can be cheap about.

There is no engineering going in bypass pipes, unlike mufflers, so not many reason to pay an extra! Only reason I see is fitment.

/!\ before buying any bypass pipes, ask the seller to give you the bolt spacing for the flange. Some might only fit if you have headers.

I added a set of secondary bypass pipes last year. TopSpeed is a vendor on the board and sold them for $160 Shipped. Not sure if the price has gone up but it is worth checking out.

If you slll the PSE...
 

I'll take your factory PSE if your interested in selling. Of course I'll cover shipping too.

I have an 01 S looking for a factory PSE exhaust

Keep in mind that there is a lot more involved with installing a PSE than just swapping mufflers. ;)

That's if you want the button and all the connections, right? The valves are normally open so you could install the muffler and leave it in the open condition full time.

Yes, the valves are normally open.

However, if you're negating functionality, it would be a lot more cost effective to just buy the $100 bypass pipes and pay your local muffler shop $50-$100 to weld them on. PSE's are not cheap.

Theres a button? for what? where?

The thread below explains it. On early Boxsters with the PSE option from the factory, there was no interior switch to control the valves. The exhaust was wired such that when the car went faster, the valves would automatically open. The early PSE had exterior shiny "sebring" style pipes that you could easily see from the rear. If you didn't get this option from the factory, many would just use metal cable wire to keep the valves open all the time, and this is fine as I'm not sure why anyone would want to silence the muffler, as even in the loud position, it wasn't all that loud. The 03+ PSEs sound better than the previous ones, as it had more growl.

On later PSEs from the factory (03 onwards), they got rid of the shiny exterior pipes, and so it looked like a standard exhaust from the outside except that the underside had valves and small pipes that couldn't be seen from behind the car. On these, there was a button on the upper console (shown in the thread below) that could open and close the valves at will. Honestly, the PSE is hard to come by now, and they don't drone, unlike most any other aftermarket exhaust (except the Dansk that I have as well as the home made PSEs done at muffler shops using the OEM muffler). If it were me, I'd keep the PSE and just get cat bypass pipes, but up to you to explore. You can definitely get a better sounding and crackling exhaust, but it will most likely come at the price of drone. Can you deal with that?

Factory PSE, where's the switch? - Rennlist Discussion Forums

Thanks guys, I didn't mean to highjack this thread but it seemed the appropriate place for it. I am gonna try to wire the valves open and see if that satisfys me. I dont think it will but who knows.
