Other than being louder are there any drawbacks to installing Fabspeed

[solihull]

Just wondering if there are any issues with installing bypass pipes (I know they are louder).

Hi Solihull,

I had the bypass pipes on my 996, they are not loud they are V.LOUD! only really suitable for fun :D

Aswell as annoying the neighbours they attract unwanted attention; boy racers and police are a particular problem.

If you want to know what you car will sound like take the mufflers off. Sounds awesome but becomes intolerable for any length of time. I've returned to the stock mufflers and have ordered a PSE system, anyone who wants the bypass pipes let me know.

One of the drawbacks I've noticed is a reduction in acceleration at low speeds. They are fine for racing as there is a little more top end power, problem is you won't be allowed to race as you will exceed the noise regulations at the track ;)

Cheers.

Well in my humble opinion, going straight thru is not going to buy you anything but a lot of noise. The only way to take advantage of bolt on mods is to have a custom tune done, that matches your configuration Putting on mods such as free flowing exhaust could decrease your performance. It's an endless cycle that we get caught up into. One mod leads to another in order to take advantage of the previous one installed.

I know you mentioned noise, but there have been studies done relating to driver fatigue vs. noise. The studies seem to point to driver fatigue increases over longer distances with higher than normal exhaust noise.

It's insanely loud. Sound like a boat on idle. I would'nt recommend bypass exhaust. I have one and I took it off after a couple of weeks.

Hi kevinmac, did you mean to quote me? If you did I'm not sure if you are agreeing/disagreeing with me.

I stated that the exhaust is too loud, reduces power at low rpm, is intolerable for extended use, not allowed on track days and attracts unwanted attention.

Porsche_911 would you really recommend this modification?

Could you clarify your points?

Cheers

I corrected my post. It's a TYPO, I forgot to add the "nt" in the word "would". I wouldNT recommend it. I agree with that response.

Just agreed with your recommendation to not do it!
