I Straight Piped My Porsche 911 and It Sounds Insane

[@jamesurban2348]

Tried this on my gt3 a number of years back. Absolutely kills the low end torque. Ended up modding the mufflers by welding in a bypass pipe. Improved the exhaust note slightly but had no negative effect on torque.

[@cyber_person]

Your gt3 is turbo’d? I thought all Gt3s were NA.

[@jamesurban2348]

[@michaels3897]

Sounds great, but $500 is a lot of money for 2 pieces of bent stainless steel. Leaving the cats means it's not straight piped, just muffler delete. Still, you're the one who needs to be pleased, and you are.

Yea, not straight piped. Center muffler is still in place as well as the cats.

[@Rick2010100]

Now you have to reset the ECU to teach-in the new exhaust conditions, otherways the engine is not running optimal. To reset the ECU you just have to disconnect the battery (negative terminal from battery) for 10-15 minutes. All data (air/fuel ratio, ignition, valve timing and control, idle speed) will now be new measured, processed and optimized.

You don’t have to do that, especially if you have a tune loaded that supports the exhaust

Even at a muffler shop at a shitty muffler shop that is cost hundreds couldn’t imagine for a Porsche as well straight piping (muffler resonator delete) in my 2009 535i cost 250 with a 20$ tip & the welds were horrible & used hideous pipes. Always go for a catback exhaust & modify that

[@bobohara3974]

Tried multiple configurations on my 997.2 C2S, this one as well. Had the local shop bend up some pipe. Hated the sound. Tried Gundo hack didn't like that. Then tried Gundo with center muffler delete (each side completely isolated) no bueno either. Finally settled on the FVD Brombacher side mufflers (no valves) with their center muffler delete (X pipe that connects both sides). Not cheap but sounds great! Quiet at cruise, almost a flat plane V8 sound at light load lower rpms, no droning, and a pissed off GT3 sound at full throttle.

[@jarrodc5455]

Note often in small high revvving 6 cyls this leads to greater peak HP but dramatically reduced torque. You should dyno.

[@brandonwade5035]

It’s a great mod. I went the eBay route and it was a good decision. I paid $120 I think and the fitment was legit as was the chrome on the tips. I love my fapspeed carbon intake but I couldn’t do $600 for the tips. Don’t forget the 2 1/8” exhaust clamps. The sound is bananas.

[@slimeade6021]

Such a fun mod. I have muffler deletes on my Subaru and I’m about to do the same to my 911. There’s little to no performance gain beyond the weight savings, but definitely worth it.

[@mferrarorace]

My neighbors and their neighbors hate me for the muffler delete on my 993TT. Fabspeed told me there is little to no drone. Well, I have never experienced more drone in my life. Is ridiculous. I expected some increase in drone but this is crazy. Gut your own mufflers and reinstall them RS stlye. Cold start in my car is freaking loud popping and growling waking up people in the am, then coming down the street at 2 or 3 am knowing you just woke everybody up is not so cool. Is fing loud, even through the turbos and cats. I coast at idle not to piss everyone off on my street, but they can already here me coming a block away. Lol. Sounds like a giant fart machine when you step on the throttle, I don't like it at all.

[@sondao8495]

I like how you walked that Prius after getting it straight piped lmao

[@ltsgarage7780]

Sounds Terrible if you ask me!!! One thing I’m surprised you did. That’s paying 500.00 dollars for two pieces of 90degree bent pipe. Why not go on the old interweb and buy a piece of stainless pipe that is bent to 180 degrees. Cut it right in the middle and call it good????

[@judihenshaw4568]

[@keithatwood5648]

I hole sawed the down pipe section of my mufflers, 45 degrees toward the ground. Only took me 2 beers. Good sound, good back pressure

[@davem5333]

Anytime you work on exhaust systems you have to expect broken bolts. The the bolts are generally not high quality but low quality with high iron content. So couple with moisture from the air and heat, the bolts and deteriorate. And they rust BIG TIME. Use a penetrating solvent like PB-BLAST or DeepCreep.

[@Engineerboy100]

You were cracking me up, you has so much fun, it was more interesting watching your reaction than listening to what you had to say about the muffler delete lol nice video.

[@Steviee8]

Very nice. I had ordered the same pipe system from fabspeed but they screwed up my order and I got a downpipe for a bmw m3. So I canceled the order and sent my mufflers to Fister and had the mod done and a beautiful polished ceramic coating done. They look great and sound is ok on throttle and not noticeable on cruising at all. Which is nice when I need to be relaxed. I still think I may do the fabspeed pipe and get it louder. I don’t care if it’s loud. It’s a Porsche and it’s meant to be heard. I think I need to compare both in person. Sometimes video clips don’t really translate the sound like being there in person. Sometimes I feel like the noise I’m hearing inside the cabin is too whimpy but I know it’s not like that outside of the car. Thx for the video.

[@richardstamper5630]

Well I have to agree with the bulk of the replies - it now sounds like a cheap car, gone is the discreet nature of the 911, welcome to the boy racer. I replaced my standard system as the original had rotted out. To be honest I was rather pleased as it allowed me to find a decent sports exhaust. I finally went for a system which came from Design 911 here in the UK. Fitting was frustrated by rusting bolts but worst of all was the manifold studs which broke at the first turn. I ended up drilling out the bolts and fitting Timeserts, these are so much better than other things such as Helicoils. I found it easier to remove the rear bumper to gain access which in itself is an easy task. The end result is extremely pleasing. Muted enough not to disturb my neighbors but loud enough when pushed through the gears. In fact it comes with the most perfect bark at high revs along with the occasional pop and bang on deceleration. Personally I couldn't drive your car without the mufflers, OK for a laugh but that's where it ends - put the mufflers back on, if only to hear that amazing air intake. Rich

[@Bazlightyear007]

Exhaust noise would be a problem in residential areas. Might even be illegal too. On a rear engined rear wheeled car, the more weight you have over the wheels, the better. You may have also negatively affected the handling/traction.

[@jamesajanda]

I bought a '99 911 Carerra that had the same thing done. The previous owner gave me the old mufflers and I just tossed them out. My car sounds AWESOME!

[@shughes911]

Back when you bought this did you do a PPI? thx

[@TinHatRanch]

I have these pipes. They are WAY too loud for the character of the car. They aren’t the loudest thing out there; straight piped Harley’s are louder, muscle cars with dumps are louder, etc. Also, they sound like garbage below 3,000 RPMS. I too wanted something louder and looked at the price of these exhausts and thought they were ridiculously expensive and took the cheap route. In the end, I took my stock mufflers and had the “Fister” mod done by a local shop.

[@Hulley29]

What's the Fister mod?

[@mellyoller]

Hulley29 it’s like a sugma mod

[@mikerinaldi4836]

My 04 Carrera S, I did the Fister mod .. I had guys who spent thousands on their exhaust envy me because my Fister sounded way better.

[@KosmicHRTRacingTeam]

How does the fister mod (which I already have) sound compared to the fabspeed?

[@TinHatRanch]

KosmicHaynerRacingTeam it is an order of magnitude less loud, but still surprisingly loud when you get on it. The sound is similar to the deletes at full tilt. Idle is a bit louder and more pronounced. The biggest difference is at part throttle, it totally gets rid of the deletes worst attributes. I experienced the deletes set off a car alarm backing out of a parking space. With the mod it isn’t much different than stock. Also, the deletes just plain sounded like a junk car with no exhaust at part throttle and low RPM. The mod totally mitigates this effect. In all but full racing applications the mod is way better.

[@Chitown388]

Would the loud sound make this car illegal for street use?

[@EatSleepDrive]

Not where I live at least. Would reallydepend on your local laws

[@prodrivebrasil]

That is the same question I had. Where I live, it is illegal :/

[@paull3179]

That car had to have a resonator installed in the intake to meet Euro noise standards as it was too loud in stock form. Mine is quite loud in stock form.

[@teinspringz]

Doesn't matter, as long as Harley Davidson bikes making more noise than this, you can make your car noisier. It's only fair.

[@Count.Zer0]

teinspringz that's pure idiotic mammal reasoning. Lemme guess, you're from USA lol

[@skrads]

If it makes you happy with this mod then mission accomplished and enjoy it! However, speaking from my own experience, you may regret this modification in the near future, but maybe not. Drone can be bad to your health, usually headaches after a short or long ride. I think the stock sound as designed by Porsche is better in my opinion. Good luck either way. Your passion for cars is great.

[@BourneAccident]

When you have rusted bolts, heat the bolt with a small torch and melt some candle wax into the rusted threads. The wax sucks right in and they come apart no problem. BTW - Porsche cat back stock exhaust systems suck big time. First thing to replace on every Porsche.

How much low end torque did you lose? Any noticeable stuff? How bad is drone at 3K cruising speed now? Can you hear the radio without high volume? Any problems with complaints or cops? I am holding off installation of straight pipes on my Cayman S because the forums say I will lose some power in the usable range. I’m thinking of putting on small race mufflers. What do you think?

[@EatSleepDrive]

It is a complete fallacy that open exhausts lose low end torque. This is a myth from old hot rodding days and there is plenty of proof showing you don't need back pressure. The car feels no different down low but feels more alive up top. It does drone when you put a load on it or light throttle. Constant state constant speed it actually doesn't really sound any different, that is until you give it even a little throttle and it really opens up. It's loud and not for everyone, if you're concerned about drone I would go another route. But as far as the torque goes, do your own research and see that torque is unaffected. www.motortrendondemand.com/detail/the-power-of-2-5-vs-3-inch-exhaust/0_y75vplrp/

[@gregoryrobins7725]

I’m referring to forum posts of 987 owners who straight piped and half complained about about the torque though It’s unclear if they deleted both main and secondary cats. I message them but never get a reply or reply on the forum. I really want to delete the secondaries but again the forum guys complain about volume. I think everyone has different tolerances. You just changed yours so you can make a fresh comparison. I was on the fence but I think I will do it now. Exhaust systems for our cars are crazy expensive. I wanted to know if the drone was overblown since it’s my daily and my commute is very long. Any problems with neighbors or cops?

[@EatSleepDrive]

I don't think I would recommend this as a daily. I haven't had any issues yet with neighbors or cops but they're sort of used to me driving loud cars lol.

[@gregoryrobins7725]

In that case I’ve been thinking one option is to put a set of small mufflers in or a set of 200 cell cats. The stock setup is so boring and really want that Porsche crackling note so I’m pretty jealous.

[@Big_M_T]

Absolutely sounds incredible. Btw, I’ve watched a lot videos with cold start ups, “I straight piped” my whatever etc., but, what I have come to find is that the only real way to tell how loud a car is is by how much you can hear your voice OVER the sound of the exhaust. Just my two cent observation. Anyone have thoughts on this?

[@EatSleepDrive]

I understand what you're saying, because there is really no frame of reference. Even with someone talking, there is a lot of variables but I think you're on to something there especially with where the mic is positioned and what not.
