I'm thinking about the Tubi street system for my 997TT. Has anyone had any codes popping up with the 200 cell cats that come on this system? Also, will my stock tips fit the system? One last question....where is the best place to purchase?
Thanks much

 

Stock tips will fit, there are a couple of sets in the fs section at considerable savings. I never had a single CEL issue in a yr.

 

Thanks for the info. I'm having a problem with the new classified section. Typed in Tubi exhaust, selected engine/exhaust, hit search and.....nothing!!

 

Tried again to search exhaust in classified. I don't like the new classified. Nothing came up. What gives?????????

 

The Tubi Street is a great system! We've had no issues with CEL's in any of the systems we've installed, and there's been quite a few. IMO it's one of the best sounding systems out there! I had one posted in the classifieds but it just sold, so if you see that ad, it's unfortunately not available anymore.

If you're interested in pricing on a new system, let me know if I can help.

 

Tom...that would be great.

 

If you just scroll down the pages you'll see a couple of sets, bottom page 8 for ex. Sorry, don't know how to paste the link.

Thanks Chris. I finally got in!!

 

Hello Dave29, I bought the tubi system from tom/Justin at rennsportone. They were wonderful to work with. I have put about 800 miles since the install on my car with no cel's, just a great sound.

 

I knew you'd love it!

 

No drone here with the SPI setup, check out these videos, although they really do not do it much justice

Rambo, feel free to give me a call or an e-mail, would love to hear from you!

If you get Toronto area enquiries I am more than pleased to give a demonstration of your system.
At our Saturday morning meet the local Porsche boys were quite impressed with the look and sounds from your system.

The switzer sounds great, what's the fitment like?

Thanks for the various offers and good suggestions (Webtool1 thanks for the offer to listen to the Switzer). If I make the change, I'll end up going with the Tubi Street version. If anyone happens to know someone with a Tubi Street on a TT in the greater Toronto area, I'd love to be able to hear.

Thanks.

 

Hi Rambo and welcome to the forum. I too think the Tubi is a good choice for Convertible, but if at all possible, listen first before making a decision! This is an extremely subjective choice and auditioning in person therefore is critical (web sounds clip are NOT reliable!), as well as educational and fun. Anyone who offers you an audition in your area, I think it's a good idea to take a listen. You might fall in love with something that you didn't plan on at all -- I did with my Cargraphic. Also, the convertible has vastly less sound proofing than a coupe (the reason why Tubi is an excellent choice for Turbo Cab-- relatively, it is more quiet and has less low frequency component/noise), so make sure you audition the "right" car.

As for resonance -- hope to help here with a few of my observations, from having listened to several exhaust systems in multiple cars. And as have been mentioned multiple times, please trust me when it comes to sound as I still listen to music using a turntable and tube components.

1. It is a very subjective description and means different things to different people. To me it is an increase in noise level, and in the case of the Turbo, this is most frequently in the 2500-2800 rpm range or so, and almost always in the higher gear, from 3rd and up.

2. Even the stock exhaust Turbo has a mild version of this. Heard in 3rd gear and up as a mild and louder hum, almost like the engine lugging noise. It disappears definitely by 3000. In fact, all resonance in the Turbo, regardless of exhaust system, should disappear by 3000. If not, you have a problem.

3. If you search the forums enough, you will see that the word "resonance" is mentioned with nearly every single after-market exhaust out there.

4. That said, in my experience, the noise is louder the louder a particular exhaust is, and the more low frequency it has. This is a fact of life: If you want a loud exhaust with a nice low frequency rumbling (things I LOVE), it's going to be louder across the range. Also important to keep in mind, the mods you put in your car, like stiffer suspension components and ECU tune, could increase the noise level and could make the resonance worse.

5. In the end, why is it not a problem with a majority of exhausts people are using? The way we drive and the way we adapt our driving. The Turbo power kicks in at 3000, so most of the times, the shift, if you are a "good" driver , is done at above 3000. Basically, you do go through 2500 rpm in first gear, but here because it's low gear, there is no resonance, then from then on you will hardly see 2500 again until cruising level.
And if you are a good Turbo driver, you don't cruise at 2500.
