Exhaust sytems

[glenf]

Hello All,

I am a new proud owner of a 2001 Boxster Base model. Came across this forum and you all are a wealth of knowledge.

I have been investigating performance exhaust systems seems the Fabspeed is direction to go.

I just wanted to hear anyone's opinions on the Borla performance and sound etc.

Thanks again!

Thanks Dubaday

Welcome!

I did the Borla on mine, it does have drone but with NY/LI driving it never seems to hit that band much. Unless the highway is clear and I am at a constant cruise speed. I don't mind it and it doesn't bother me either. It is fairly loud with the top down, but that growl is awesome when you get it on it.

best bet is to listen to them and make the call yourself.

Thanks for that info. I cant seem to find any soundclips other then the "S" version

I have the Base 986

do you think it will sound significantly different then "S"

also what do you mean by drone? appreciate the feedback

Drone is the harmonics created by the exhaust valves that becomes more noticeable as the exhaust header material gets thinner. Most, if not all, aftermarket headers are made from thinner metal, usually aluminum, so they will have some degree of drone. You've probably noticed the OEM headers on your Box look like they came out of a Soviet submarine they are so thick and clunky looking but work very well and don't have drone. I've got the Fabspeed on my '99 and there is drone around 2.5K rpm but when it hits 3K rpm the exhaust note is a symphony. It is hard to describe drone you really have to hear it and it does drive some people crazy. Find a sound byte of it before you change out your headers so you know if you can handle it and buy a good set of headers that have a splitter in the junction box, smooth bends and cleaned up welds especially at the flange openings.

[glenf]

Much appreciated. However I was thinking strictly a cat back system without the header kit. What do you think?

The borla system and the eBay systems you see are pretty similar in design. There is no balance pipe between the two mufflers so drone is introduced. The fabspeeds has a pipe that connects the 2 mufflers and negates the drone.

I don't think the sound will differ between an S and non S.

If you are in LI/ Nassau county area I would be happy to catch up on a weekend morning and you can hear the borla for yourself.

So you just want to replace your muffler? Dansk makes mufflers for Porsche and they have several models that replace the stock. They are lighter, polished, give you twin pipes and sound great. I have the "sausage" sport version on my base '99.

I have one of these I've yet had a chance to test. From what I've read on here and youtube, it's not much louder than stock. It's also only 3 lbs lighter than a stock muffler. Sound is important to me too, but I want to loose that boat anchor muffler too. I'm half tempted to cut it open to see if there's any weight I can remove from it.

My 3.6 has headers, cat delete pipes and a GHL twin can muffler. Love the sound of the muffler but it is a little loud and does have drone at 2400 - 2800. I have been thinking about what to do as I don't want to quiet it down too much and don't want to add much weight. I finally decided to add two resonators ( one each side ) before the u-bends leading into the muffler. Took it to a local Porsche shop and they took some measurements and we're going with 12 " overall length Vibrant brand . They came in today I'm dropping off the car tomorrow morning. So I'll chime in tomorrow with the results but I think it will take off just enough edge/resonance to make my exhaust perfect.

It sounds much better and louder than stock unless you open the stock muffler up and cut a hole in the first baffles at the intakes. That allows the exhaust gases to go straight back to the outlet instead of winding through the other baffles. I had that done to my OEM and it was a toss up on sound but the Dansk looks much better and I like the dual tips instead of the whale blow hole.

I have gone from the stock 2001 S muffler that came on the car to a 2003 S muffler modified by FDM (FD Motorsports » Fister Exhaust – Boxster) to an OEM Porsche Sports Exhaust (PSE). The FDM had the best sound by far and I liked the larger tips. But, the PSE is special. I ended up deleting the secondary cats to get some sound out of the PSEs. No drone at all with the FDMs. The other two being stock also had no drone.

Chuck that PSE looks amazing! special indeed!
hopefully at some point you can put up a video for us with the PSE and secondary cats deleted, would love to hear that.

i just installed the Fister that you used to have on and i think it sounds amazing it's really making all the right noises BUT deleting the secondary cats is a MUST if you are to get any sound out of it. no drone is also very nice!
i highly recommend the Fister to anyone, a bit pricey but still under the more expensive high end aftermarket ones that sound.. aftermarket.. not that it's necessarily a bad thing but i prefer that Porsche dirty sound.. sounds like something is broken inside the engine and i LOVE IT!

i will try to upload a video of it soon.

What's the difference between the fister and Pedro sport exhaust? Are they basically the same thing or is there more to the fister? Better sound than Crios mod?

This is what you should listen to. Only exhaust system I can personally say has zero drone (other systems I rationalized for awhile, eventually drove me nuts with their drone) is from FD Motorsports.

I have the PSE (welded open) on my '01 S. I really prefer the look of the standard S and would like more sound. How does yours sound with the cat delete? Any negatives to installing them? I've been tempted to go the eBay route because they're cheap, have the OEM S look, and from what I've heard, actually sound decent.

Try to drive one with an "Ebay" exhaust if you can- before you buy. I installed a Beluga cat back and found the volume and drone offensive. After two weeks I reinstalled my Crios- modded stock one. Now I can hear my stereo and I'm not embarrassed to drive in my quiet neighborhood.

I installed the TopSpeed Cat Delete pipes. They were $160 shipped from TopSpeed. It improved the sound (IMHO) but still is not as good as the FDMs. The install was easy but I have heard that the cat delete pipes could cause heat issues to the drive shaft rubber boots.

I am not sure what you did when you "welded open" the PSEs. The default to the valve is open... the louder position. If you welded the valve open you may have set them to the quieter position.
