Well, I have been contemplating my new AH pipes since they were installed two weeks ago. The car sounds like a f-car, and I loved the sound when I was by myself. HOWEVER....I could tell my date was not thrilled with the race car sound last night So, it is time to trade to something more date friendly.

Besides the PSE, are there any other systems that are controlled via valves? I know the SpeedArt 997.2 system is available. Anything for the 997.1? If AH was controlled via valves, that would be a sick system!

Also, let me know if anyone wants to swap 997 mufflers. If you want a more aggressive sound, you won't beat the AH.

Find another date. Quick.

 

Seems like there's money to be made by building a valve set that can be adapted to all the muffler systems out there. RF controlled (like the new coilover lifts) or dash switch. Geez, I wish I was just a bit handier...

 

Nah, she just had to talk a little bit louder!

 

Nice.

 

How would a valve work without a bypass set up built into the cans? It seems to me the mufflers would need to be designed to accomadate a valve allowing a mild to wild sound variation.

 

On this note, what you really need is a PSE system adapted to full bypass in sport mode, and full muffler in non sport. Shouldn't be too difficult. My wife and I really like the bypass pipes, so we ditched the PSE altogether to save weight.

However, if PSE in Sport mode did offer full bypass, it would be worth the weight (almost) to keep it in. It's just that in our opinions, PSE Sport mode was not loud enough.

I think this would be something a muffler shop could do for you. PSE in non sport mode is definitely conversation friendly.

 

I saw an ad in Excellence Magazine for a Tubi system that had the same valve as the PSE, I haven't seen much about it since. Try their website.

 

A valve setup would never work with the AH setup..it's basically 2 small glass packs welded in place.

Yes, I was referring to the valve concept....quite/loud on demand.

Nick I sent you a PM in regards to your exhaust.

 

Muffler shops can usually install the bypass valves, but they are not good at on/off switches (electronic, RF, etc.)... You should talk to someone qualified that has done the switches, unless you want to crawl under & manually switch the valves on/off. As for the loudness of the current AH pipes, it's all just foot controlled

 

My PSE combined with X51 headers and AWE 200 cell cats sounds very aggressive in sport mode and very tame when in "normal" mode. However I have the plug which controls the vacuum unplugged so it is in loud mode all of the time. Can easily go between plugged and unplugged though.

 

Bypass valves won't work n the AH setup because there are no chambers. With a bypass valve you can convert the muffer form a 2 chamber to a 3 chamber. With the AH setup...here's a pick.




The quiet mode will be the original configuration. If you bypass those small expansion chambers it would basically be a complete muffler bypassmaking them even louder.

Nick,
how much r u letting them go 4? Remember she absolutely HATED the sound. U better move quickly or the only hummmm u will be feeling is the hummm of the mufflers
