What made you choose this particular product?
Best price for an all stainless full 2.5" catback for the S4.
What were you trying to accomplish by adding this product?
Better sound with the top down and was listed as a requirement with the JHM ECU tune.
Was it easy install? Any installation tips that will help others?
Fairly easy. Previous notes outlune the changes needed to adapt this to an S4 Cabriolet, when it was designed for the RS4.
Once you’ve had a chance to use the product, did it meet your expectations?
More than met expectations.
Any additional comments?
All S4's need an exhaust. They all make this car sound so much better!
