NEW DESIGN! The Hyperflow Exhaust Down Pipe with a high flow catalytic converter uses a massive cast 304 Stainless Steel Bellmouth that tapers to 3.0 inch piping where it connects to the mid-pipe. Unlike previous designs, the new downpipe will bolt to any stock or 3 inch aftermarket catback exhaust system.

Features:

• Two-piece design:
  • Reduced shipping costs
  • Delete the catalytic converter without having to buy a whole new downpipe (Catless Race Pipe WS02-RP sold separately)
  • Easier installation
• Cast 304 Stainless Steel Bellmouth upper section for maximum exhaust gas flow
• 3.5 inch diameter 304 Stainless Steel pipe tapering smoothly to 3.0 inch
• Spare wideband oxygen sensor bung included
• Modified pipe path to provide more ground clearance for lowered cars than previous design
• Hand TIG welded polished to a show quality finish

Vehicle Fitment:

• Subaru WRX 01-07 (Manual)
• Subaru STI 01-07 (Manual)
