hi guys,

i am considering to do a secondary bypass for the gts rather than to buy the fabspeed option

To be honest, rather than cost factors, I prefer if I can do it right away at the exhaust shop.

Can someone tell me if this is a safe route?

I have done custom bypass pipes before and they work fine but thats on another car.

 

As long as the shop you take it to can fab it up, have no leaks when it's all done it will be fine. It made a big difference when I had my 04 CTT.

 

If time is of the essence, we can ship a set out to you right away! Let me know.

 

Hi , I have actually thought of doing it locally already but pmed me the pricing and delivery timing thanks

 

Hi, thanks for your message.

I think so too.

I always wonder the difference in material used by custom shops and the Superior fabspeed ones.

I wonder if it makes much of a difference.

 

I went to a local exhaust shop here in the UK yesterday and they said it needed 3 hours per side of labour to get the old ones off and new ones in, including fit up for assembly, needless to say it because expensive, twice the price of the pipes themselves @ £160 for the parts £320 for the labour, is it really 6 hours to remove and install?

 

There is a sharkwerks bypass set for sale in the classifieds here.

 

Suncoast had my Fabspeeds installed in about 2 hours on MY2014 TTS

 

Should be easily do able at a reputable shop. There really is nothing to do it.

 

Great to see some discussion going on.

Specifically talking about the 958 GTS here but I guess the idea is similar.

So I guess going to a custom shop is safe enough.

If theres anything I should be converned of, let me know

 

Well, I would just install what is available for the car (which I did) from known and reputable exhaust companies. I wouldn't just let someone fabricate those pipes and install them in my car, especially around here .There is always a chance for things to go wrong, which is fine since you're doing this from scratch. But, is it really worth it? and your doing this to a new Porsche?

 

thanks for all the various comments.

Anyway have estimate on the price to custom fabricate these pipes?

 

do all GTS with secondary bypass make "the burble" sound? mine is a S with bypass and PSE but doesnt make it no mater what i do :S

 

M3- I like to know that as well.

In fact thats the main reason behind this over the quicker Turbo

The burble sound is really nice, I am really curious what it would sound like with a secondary cat bypass.

 

Been busy lately and had no time to update my progress.

I have gotten the customize pipes done.

Heres to share my experience:

-Custom Pipes work just fine ( 3 hours hammering+1 hour sourcing material parts)
-Cost about $300USD
- the sound is exactly the same but x 3 times louder
-Cold Start is Very Loud and will be with or without sportsmode
-If sports mode or exhaust button is off, the crusing noise is almost as quiet as before.

Only thing I wonder is there is a lot of burbling when you let go the throttle in sports mode/exhaust valve open

I do like the cracking noise but just wanted to know whats causing this noise.
