I put a TFX header and exhaust on mine about 3 years ago. I did not have the cash for the stainless Borla. The throttle response is much better, plus it sounds very throaty. It was only around $350 for the entire exhaust and worth every penny! Pain in the butt to install the header. It was not a perfect fit with the intake manifold. Minor fabrication was needed, so you may want to spend the extra $$ and go with the Borla if that fits perfectly.
