Been leaning somewhat towards Capristo (ave $) and Akraporic (high $) exhausts and wonder how they compare with the 6-speed popular Europipe and Tubi?.
I guess these all have 200 cell cats. I know Akraporic has a 400 cell cat, but can't find a sound clip for the 400, their 100 cell unit is loud. Anyone know how the Capristo compares to Tubi in sound....these two units run about the same price.
I like the low price of Capristo and for $1100, you get a remote to regulate exhaust sound from high-sport to near stock.

 

John,

Another option is our AWE Tuning system. We use a 200 cell HJS cat, stainless steel, tig welded, and most of all, they are made right here in the U.S.

Being made here in the U.S. means that you will not end up paying the costs to import a system. Those fees can drive up the retail price on items made overseas.

Unfortunately the same holds true for us if you live outside the U.S. and want our products...

Agree with you, but really have been searching for a remote to soften the exhaust when a lady is present or businesss reps, and then harden the exhaust otherwise. I found a mechanical switch that I aborted because of making a hole somewhere in in my baby's shell.

 

Akrapovic 100cpsi setup is not loud at all. The center muffler provides very good sound suppression on a car. As an example, on 997.2 the 200cpsi catalytic converters make the car too quiet.

 

Forget about soundclips - in Florida you can probably find an example of one of every type sold - you need to listen in person both outside and inside.

 

I wish that was reallyb true .... I think that can be true only if you live near a popular installer or at least near a big city like maybe Atlanta size.

 

But if sound is really that important to you, you'll want to hear in person.

 

I agree, you certainly shouldn't spend the kind of money that an exhaust goes for unless you hear them in person. The akrapovic sounds wonderful to my ears.

 

Innotech has many variable exhausts setup in SS and Ti but may be on the loud side (no cats).

 

That's why i want the remote
control for different level of sound/resonance.
Impossible in area where i live to
track down a turbo less one
upgraded exhaust and even less chance
to find one i prefer out of
>40 exh- systems out there. Remotr gives best chance a screw up occurred or you get tired of too deep/loud sound and need a break. That can always happen.

 

Where in Florida are you?

Also, you are not asking anything completely out of the ordinary. Everyone wants something subtle during highway cruising, but ear shredding when you are alone and go wide open throttle.

Don't be fooled. You can have both!

We have found that perfect balance.

We design and make our products with discerning clients in mind that don't want to attract the wrong attention. Many users might have spouses and clients in the car and want to be able to carry on a conversation. I am sure you will probably want to hear the radio and speak on your cell as well, right? You might have to tip-toe out of your gated community earlier in the morning on the way to work...

All of these things are taken into consideration. This is not a racecar and does not need to sound like one.

I will say it again. You can have both.

Call or email if you want me to go into further detail.

 

We have our World Challenge GT sport exhaust for the 997TT and many members have them system on there car.
GMG was also the first company to pioneer the now copied X pipe design - years ago.
A proven performer- with great sound and proven power gains!

Not to hijack the thread but I have always been curious if an expert could give the pros and cons of some of the more popular systems in certain price ranges...i.e sound quality, resonance in3K range, 4-5K range etc...
There are so many choices.

 

For those interested in various sound options, especially a quiet level which is difficult to source....Our 997TT cross-flow system is available in several sound options including quiet, moderate or loud levels and is very flexible in terms of changing the sound after the purchase should you desire a change in sound. Due to the modular design, we can always supply a single component to swap out, which can totally change the sound to your liking.

The SpeedTech 997TT X-cellerator cross-flow exhaust system is a fully modular system with V-flange couplings for quick and easy changes between components. Optional cat bypass pipes and muffler bypass pipes are available, making this a very flexible system for a variety of uses...street or track use, it only takes minutes to swap to a different configuration. Our standard system is a 100 cell Hi-Flow cat “street” version, which re-uses the OEM tips. The 100 cell, 130mm european hi-flow cats enable extremely quick turbo spool. A catless “race” version is optional, as are mirror polished finishing, ceramic coating, twin tips and true dual, full 3” outlet tips.

The 997TT X-cellerator is available in four sound levels to suit a variety of tastes.

2.5 quiet (conversation, phone calls, radio are all very comfortable, yet still provides a great GT3 type sound on the exterior) - the perfect daily driver exhaust! No drone - fantastic sound.

2.5 sport (a little louder than the quiet, also a good daily driver for those desiring a little more aggressive note, but nothing too dramatic)

3.0 moderate (aggressive cross-flow tuned sound, not over the top, but getting louder...)

3.0 loud (full 3” system—screams at WOT. The exhaust is definitely being heard in the cabin! Sounds awesome / very aggressive both inside and out. Trademark GT3-like cross-flow sound). Super sounding system, but too loud for regular cell phone use.

This system features a cross-flow muffler design that produces our trademark exotic cross-flow sound, which is held in very high regard by many Porsche enthusiats. For those unfamiliar with this type of exhaust, the cross-flow design emits a very exotic, high end, tuned sound—a lot like a Porsche GT3, which is great news for Porsche turbo owners, as this normally aspirated, highly desired sound is very difficult to achieve on a turbo car. There is a video link below if you wish to hear it for yourself.

High quality materials and construction, ease of installation, weight savings, user friendly options and exceptional sound were our design goals for this system and we feel we have exceeded even our highest expectations.

The SpeedTech X-cellerator exhaust is a top of the line, no compromise system for the discriminating Porsche enthusiast and very fitting of a 997 turbo. Not only does it offer just about any option one could desire in an exhaust system, it is relatively quick and easy to swap between power and sound levels. For instance, the switch from a full cross-flow muffler configuration to straight pipes can be done in 5-10 minutes and then switched back again in the same amount of time.

We offer special 6speed member pricing on all systems. There are several component and sound options, including a full 4-way system bundle (all modular piping options purchased at one time), full 3” tips, cat delete, etc. Please PM or email for pricing.

The SpeedTech X-cellerator is constructed of 100% stainless steel and made in the USA.

Please take a moment and view the video below. We look forward to hearing from you with any questions you may have…

There are many good exhausts. The new awe crosspipe looks interesting. As far as euro exhausts, look no further than EP. Tubi no longer makes the single can system, the multi-piece system will drone. If you can find a early tubi, that would be good, pm brownan, he might have one.
The Ak has a CEL issue that needs to be resolved. The Cristo one has some rough looking tips, I wouldn't go with either. FVD, TA and 9ff also have switchable exhausts.
