Fabryce+Ryne,
Just installed the world challenge downpipes in my S5, the car sounds awesome. I'm very satisfied and it is the best setup I've tried thus far.

Any update on the air intake + ecu?

 

Alwin!

Thanks for the kind words!

Ecu should be ready in about 2 weeks, GIAC has had my car for a week now and they are re-writting the software.

As soon as its available I will post up!

The intake will take a little longer but the software will be available shortly.


Thanks again!

 

Are the mufflers thermal coated black, also? Or can you order the system w/the mufflers coated? I'm not a big fan of seeing the polished mufflers under the rear valence.

 

Hey Fabryce,
Will you be developing high flow cats for the S5?

 

Won't be cost-effective. Too much labor involved since you have to drop the engine to get access to those components.

 

Gentleman,

1. You can order the exhaust system to have the tips thermal coated or the mufflers and tips coated.
2. I am going to build some down pipes with hjigh flow cats for my car and see what kind of performance increase we see.

If there is enough demand we may build a limited # of sets.

There is a bit of labor to install the downpipes but no more than there has been on a B5 s4 2.7t.

Stay tuned!

 

Now, now, lets get that intake and ECU stuff wrapped up before you get distracted by all the other cool stuff you can do with our cars.

 

Software should be ready in a week or two.
