By eliminating the factory catalytic converters, STILLEN has successfully improved flow, creating power gains as well as dramatically improving sound. Catalytic converters are not only very restrictive to the exhaust flow and performance, but they also act as mufflers, greatly reducing the sound that enthusiasts desire.
These Cat-Delete Y-Pipe Systems are TIG welded and constructed out of 304 stainless steel with laser-cut and CNC machined 304 stainless steel flanges.
Quality is not comparable with Y-Pipes from other brands like HKS, Tanabe or Fujitsubo! But the price is much lower and you will get a PnP Pipe with acceptable quality!
