Szymon did it on his C4S last week. Prepare for the thunder and tickover like a V8.

Craig's car on here came with this setup when he bought it.

It's awful!! Completely loses the flat six sound and is just a horrible noise that will annoy your neighbours and anyone you overtake.

But sometimes it's best to experience stuff for ourselves so by all means give it a go.

Coincidentally Craig fitted Topgear X pipe cats and switchable boxes last year. This gave the option of quiet or louder.

He's recently added the Topgear manifolds too and it is a step too far.
On loud it now sounds like his old muffler delete setup. Hooligan loud and not very nice at all.

Good luck with finding the sound you're after though. Thumb

Indeed,it’s fine line between improving the noise and making it sound like your exhaust has fallen off!

My car currently has no backboxes while I wait for some bits to arrive. I had to start it up to move it back into the garage, I would assume that with no backboxes it's basically the same as having those bypasses.

It sounds awful. Contrary to the above, it doesn't sound like a V8, it just sounds rough. Like a knackered old tractor. And that was just at idle. I'd feel like an utter c**t driving anywhere making that kind of noise.

I had the muffler delete on my Cayenne, which IS a V8.

To be honest its too loud and at some point I will reverse it. The car sounds rough, because the resonance doesnt match. The gasses must be flowing around all over the place.

Sounds awesome on tickover though.

My 996 has PSE, which to me is the best sound.

On my 964 I have a G-pipe, and Cat delete. That sounds really good, but have to put the secondary muffler back on for track-days, as there is no way it would pass a noise meter test.

My AMG C55 is a 5.4 V8, but you'd never know anywhere below 4,000 rpm as it's so quiet - I'm somewhat torn on this one as I do like the sound, but also the character of the car rather suits the subtlety. I would fit a sports exhaust if there's an OEM one, but if it made the car drone at cruise or annoy the neighbours it'd come straight off again - this is the car I drive to Heathrow at 5am.

Hi Exel,

Its not so much how loud it is that was the issue, Porsche sound was not there at all, but more the noise it made on overrun.... When on full throttle its like thunder, but on lift off the noise make the car sound bloody awful. That's just my opinion obviously. Also, at 70/75mph the drone in the car is deafening !! so you either need to drive everywhere in 5th or faster.... choice is yours.... ha.

Hopefully they might be different on yours..... Good Luck Thumb

Craig

I bought my car last year, it has bypass pipes. I can confirm it not a good sound, it is very loud which some owners mistake for good but speaking from having had several cars over the years with many different exhaust options this is by far the poorest sound on any of the cars, it has none of the flat six sound and it just a poor facsimile of a lumpy 8 pot. If you ever embark on a journey where you have to maintain a steady 50-70 then take nerofen with you as you will have a headache by journeys end! The drone that resonates through the whole car is terrible. Anyway like most things it very personal to the individual and there will be some who love this sound.
I have now bought some very low mileage original mufflers which I have now had modified by Carnewal. My past experience with Gert’s modified exhausts have always been very positive, my 993 RS rep had the RSR boxes and they were fantastic. My wife’s Boxster S still has the original GT exhaust on it some 9 years after fitting (ours was the original test Boxster for the exhaust he sells, I approached him to consider making them and after 2 goes we got the sound right! So all the Cayman and Boxster owners with the GT exhaust fitted you can blame me if it’s not to your liking 😎)
So when I get the mufflers swapped over there will be a pair of delete pipes up for grabs, very shiny as they not had any use for reasons stated above.
As with everything it your choice and this just my opinion for what it’s worth.

All the best.

Do you guys that have tried bypass pipes think theres a difference if its a 3.4 ,3.6, 3.8 that its being done to.

if you have spare time have a look at this you tube vid I found of our recent trip to Dinslaken , the boxter in the final 5 was not the loudest but had a nice exhaust note best I have heard on a boxter . some nice exhaust notes all slightly different , and forgive the strange Englishman dressed as Batman lol

That Boxster sounds just like my wife’s car! It a world away from the stock muffler sound. But the good thing it is the stock muffler but with the secondary cat material and some sound deadening removed, definitely seemed to rev more freely compared to the original stock setup. If you Norfolk way anytime feel free to come listen/go for a spin to see what you think.
I just about to fit my 3rd Carnewal exhaust (3 different models) personally I like the sound, the fact you using the original super long lasting original muffler too (Boxster one been on the car for 9 years! Gone from 10k miles to 60K) still perfect!

Hi,

first to be clear I have removed my PSE to repair it....... some day, and for that time I have similar setup like from website for all £20, you can see picture in this post: http://911uk.com/viewtopic.php?t=127213&postdays=0&postorder=asc&start=40

now to consider:
1. you will notice drop in torque from start to about 4k then it pulls like a.....PORSCHE with more pony's
2. there is more bass on start up and overall more noise but I don't think is louder then PSE on, as on last meeting few members pay attention to start up and rev everyone was surprise how not LOUD this setup is ask ALEX,
3. sound wise..... somehow it sounds when idling like v8 this is crazy, between 2,5-3,5 rpm it screaming like F1 and it is noisy inside after 4k you are in comfort zone but on long trip I would not recommended as you will suffer from headache or very bad MPG Floor - I don't mind any problems above as my best MPG so far is 19 and barely use it 4th gear
4. if you do not push hard it is not louder then PSE on low rpm
5. some people like it some not, my wife dislike it and she is only one complain so for myself this only reason is enough to keep it without boxes Mr. Green . So far all told me to keep it without boxes.
6. as advert says "Significant weight saving"

As for today I was studding exhaust systems for last 3 weeks and if you would like to delete boxes you will have to do it differently for that reason I will do my own exhaust but need some more info.

I can only tell if you would like to remove boxes then you need to check CAT as if CAT-s falling apart it will make funny noise and you will not like it (mine do) I will be speaking next week with manufacturer about steel CAT-s for my car last longer and better flow win win, also this kit from website is not good same as mine to do it right should be long pipe from CAT bend it around in space where boxes are and to tail pipe by doing so you will not lose power and could gain some also should be different noise more refine as you have with front engine cars american V8-s (longer pipe), I have to visit my local specialist and speak with him about my plan and perhaps if money will be ok I will do long pipe to check my theory.

I will record tomorrow (today) with gopro startup on cold engine warm engine will rev it drive it fly it etc. so by tomorrow will be link to red tube Hand sorry youtube and today I attend sea bath at landudno so if you around find black 996 take a look on rear and wait for me Cool I'm off find my swimming shorts Bandit

2 types of drivers.

1) muf delete drivers, hard drivers, love speed, love mods, love driving porchse how it should be driven.

2) those that like it stock, quite flat six, that go out once a week to the store and back before they get dirt on it.

As for the assumption on types of drivers, that a little erm... incorrect! It’s an assumption that because somebody who dislikes the sound something makes that they then opposed to speed, mods, driving a Porsche properly. Perhaps read the comments I made especially about assisting the development of an exhaust sound on a modified exhaust that sells pretty well!
Like I said it’s all individual opinion to what sound is, what is good and what is not. But don’t mistake the fact I and others happen to dislike the noise the muffler delete pipes make and the fact it resonates through the whole car with someone who dislikes mods, does not like to drive fast, and doesn’t drive a Porsche how it should be driven.
I now on my 14th Porsche, I have have driven many of them all over Europe, vmax’d my tuned 997TT in Germany recording 212mph,
Have done numerous track days in Porsche’s and my Clio Cup race car, driven several F1 cars in the past at F1 experience in the South of France and U.K. so I think that ticks the speed box! As for a hard driver, what is that? Someone who has big guns, beats anyone up who disagrees with them, someone with no mechanical sympathy? Or just drives fast?

Porsche’s are different things to different people, one person’s daily is the nexts concours entry, some are rallied and never washed some are kept pristine but don’t make an assumption that anyone type of owner is better, superior or more a Porsche fan than the next one I certainly don’t

I happen to dislike the sound of delete pipes for reasons in my original post, but don’t Jump to any assumptions as to the type of Porsche owner I am or anybody else as without knowing them how can you possibly be right.

I totally happy for anyone who wants to fit bypass pipes, if that floats your boat go for it. Like I said I got a nice shiny set someone can have once I get my MODIFIED original mufflers onto my car.

Enjoy your Porsche this Sunday, whether it flat out on a road or with the wash mitt!
